What benefits, if any, do you gain from completely shutting down your computer?
From a software perspective, an operating system and the programs you run on it tend to accumulate all sorts of cruft over extended periods of use â€" temporary files, disk caches, page files, open file descriptors, pipes, sockets, zombie processes, memory leaks, etc. etc. etc. All that stuff can slow down the computer, but it all goes away when you shut down or restart the system. So shutting down your computer every once in a while â€" and I do mean actually shutting down, not just hibernating or putting it to sleep â€" can give it a “fresh start†of sorts and make it seem nice and zippy again.

solenoid
"A solenoid (from the French solénoïde, derived in turn from the Greek solen ""pipe, channel"" + combining form of Greek eidos ""form, shape""[1]) is a coil wound into a tightly packed helix. The term was invented by French physicist André-Marie Ampère to designate a helical coil.[2] In physics, the term refers specifically to a long, thin loop of wire, often wrapped around a metallic core, which produces a uniform magnetic field in a volume of space (where some experiment might be carried out) when an electric current is passed through it. Solenoids are important because they can create controlled magnetic fields and can be used as electromagnets. In engineering, the term may also refer to a variety of transducer devices that convert energy into linear motion. The term is also often used to refer to a solenoid valve, which is an integrated device containing an electromechanical solenoid which actuates either a pneumatic or hydraulic valve, or a solenoid switch, which is a specific type of relay that internally uses an electromechanical solenoid to operate an electrical switch; for example, an automobile starter solenoid, or a linear solenoid, which is an electromechanical solenoid."

Which of the following utilities enables a Windows 7 user to edit a file offline, and then automatically update the changes when the user returns back to the office? A. Sync Center B. Windows Aero C. Windows Defender D. HomeGroup
"A. The Sync Center is a feature of Windows that enables you to keep information synchronized between your computer and network servers. You can still access the files and modify them even if you don't have physical access to the the server; in this case they are modified ""offline"" and are synchronized automatically when you return to the network. Some mobile devices are also compatible with Sync Center. The Sync Center can be configured within the Control Panel. Windows Aero is the premium visual experience included in some versions of Windows Vista and Windows 7. Windows Defender is the free Microsoft antimalware program. HomeGroup is meant to quickly and easily share printers and media between Windows 7 computers in a home network."

Remove then re-insert the card. C. Blow on the end of the card to clear out dust. D. Pull up on the tab on the left side of the card.
"D. Some SD cards have a write-protect tab within the notch on the left side of the card. Sliding the tab down ""locks"" the card so that it can be read from but not written to."
DAC
"DAC discretionary access control In computer security, discretionary access control (DAC) is a type of access control defined by the Trusted Computer System Evaluation Criteria[1] ""as a means of restricting access to objects based on the identity of subjects and/or groups to which they belong. The controls are discretionary in the sense that a subject with a certain access permission is capable of passing that permission (perhaps indirectly) on to any other subject (unless restrained by mandatory access control)""."
[4.3.1] What is a name of a memory for dynamically allocated objects in C++? How to access this memory?
"Either ""free store"" or ""heap"". Access is done by using C-style ""malloc"" and ""free"" functions or C++-style ""new"" and ""delete"" expressions."
Baud
"In telecommunication and electronics, baud (/ˈbÉ"Ëd/, unit symbol ""Bd"") is synonymous to symbols per second or pulses per second. It is the unit of symbol rate, also known as baud or modulation rate; the number of distinct symbol changes (signalling events) made to the transmission medium per second in a digitally modulated signal or a line code. Baud is related to but should not be confused with gross bit rate expressed in bit/s. However, though technically incorrect, in the case of modem manufacturers baud commonly refers to bits per second. They make a distinction by also using the term characters per second (CPS). In these anomalous cases, refer to the modem manufacturers documentation to ensure an understanding of their use of the term ""baud"". An example would be the 1996 User's guide for the U.S. Robotics Sportster modem, which includes these definitions."
"Is this code correct? char target[6+1+6+1], *source1 = ""Hello,"", *source2 = ""World!""; strncpy(target, source1, 6); strncat(target, "" "", 1); strncat(target, source2, 6);"
"No, because we have to remember about NULL character while invoking strn* functions. Correct sequence is: strncpy(target, source1, 7); strncat(target, "" "", 2); strncat(target, source2, 7);"
Is the following situation legal? //file1.cpp const int counter = 10; //file2.cpp extern int counter; int counter2 = counter;
"No, the program is illegal. It should be as below: //file1.cpp extern const int counter = 10; //file2.cpp extern const int counter; int counter2 = counter; Any variable, that is used in more than one file requires declarations that are separate from the variable's definition. Nonconst variables are extern by default. That's because if is that so, then we can use const in headers. And the rule ""one definition, many declarations"" is then not broken. But const variables declared at global scope are local to the file in which the object is defined. So that variable cannot be accessed from other files. We can make a const object accessible throughout the program by specifying that it's extern."
What does ESX stand for?
"Officially, nothing. Unofficially, it stands for ""Elastic Sky."""
What is a dynamically typed language?
"Something that allows this: employeeName = 9 employeeName = ""Steve Ferg"""
"In C, I can do like this: char s[]=""hello""; or char *s =""hello""; So I wonder what is the difference? I want to know what actually happens in memory allocation during compile time and run time."
"The difference here is that char *s = ""Hello world""; will place Hello world in the read-only parts of the memory and making s a pointer to that, making any writing operation on this memory illegal. While doing: char s[] = ""Hello world""; puts the literal string in read-only memory and copies the string to newly allocated memory on the stack. Thus making s[0] = 'J'; legal."
extern declaration keyword
"The storage for the variable is created elsewhere, used to export datga to other cimpilation units This keyword is a way to tell the compiler ""the variable exists, but it's in another 'external' location"". Typically this means that one .c file is going to use a variable that's been defined in another .c file."
What escape sequence is used to print a double quote character?
"\"" aka the double quote escape sequence."
What are escape sequences defined by the language?

ATAPI
"advanced technology attachment packet interface ATA Packet Interface (ATAPI) is a protocol that has been applied to ATA that allows a greater variety of devices to be connected to a computer than ATA would allow. ATA was originally designed for, and worked only with hard disks and devices that could emulate them. The introduction of ATAPI (ATA Packet Interface) by a group called the Small Form Factor committee (SFF) allowed ATA to be used for a variety of other devices that require functions beyond those necessary for hard disks. For example, any removable media device needs a ""media eject"" command, and a way for the host to determine whether the media is present, and these were not provided in the ATA protocol."
MAID
"an architecture using hundreds to thousands of hard drives for providing nearline storage of data, primarily designed for ""Write Once, Read Occasionally"" (WORO) applications, where increased storage density and decreased cost are traded for increased latency and decreased redundancy."
ATM
"asynchronous transfer mode Asynchronous Transfer Mode (ATM) is, according to the ATM Forum, ""a telecommunications concept defined by ANSI and ITU (formerly CCITT) standards for carriage of a complete range of user traffic, including voice, data, and video signals"". ATM was developed to meet the needs of the Broadband Integrated Services Digital Network, as defined in the late 1980s, and designed to unify telecommunication and computer networks. It was designed for a network that must handle both traditional high-throughput data traffic (e.g., file transfers), and real-time, low-latency content such as voice and video. The reference model for ATM approximately maps to the three lowest layers of the ISO-OSI reference model: network layer, data link layer, and physical layer. ATM is a core protocol used over the SONET/SDH backbone of the public switched telephone network (PSTN) and Integrated Services Digital Network (ISDN), but its use is declining in favour of all IP."

In a given code: size_t n = get_size(); int *p = new int[n]; for(int *q =p; q != p + n; ++q) {
//array processing } what will happen when get_size() returns 0? "Then code will be still valid. The language specifies, that using ""new"" to allocate an array of zero size (which otherwise is impossible), it will return valid, nonzero pointer which will be distinct from any other pointer returned by ""new"". Such pointer cannot be dereferenced (because it has no elements) but can be used in comparizons. So if ""n"" is 0 then body of the loop is not executed."
What can be a problem with the following code? if(val == true) {

A technician is attempting to backup 5 GB of data to an external hard drive that has been formatted as FAT32; however the backup keeps failing. What is the best way to solve the problem? A. Reformat the drive as NTFS. B. Replace the drive. C. Back up the data to a USB drive. D. Back up to CD-ROM.
A. If the backup keeps failing, you should look at the file system used on both drives. If the drive where the data is backed up to uses FAT32, and there is currently no data on the drive, it should be reformatted as NTFS. NTFS is the superior choice for a variety of reasons, plus it is more common than FAT32. Always try to reformat the drive before you incur the cost of replacement. From the scenario, you don't know the original type of backup drive. It might already be a USB drive, but who knows? Many USB flash drives are preformatted as FAT32. Regardless of all this, before trying another drive, try reformatting to NTFS first. A CD-ROM does not have enough storage space for the amount of data you need to backup. Plus, optical media is good for long-term backups that won't be used often. But if the technician in the scenario is trying to back up to hard disk, then it can be assumed that the data will be needed more often, and requires a faster solution such as SATA, or at least USB, either of which should be formatted as NTFS.

One of the tape drives in the server room is reporting errors. What should you do first to maintenance the tape drive? A. Use the included cleaning tape for the drive. B. Uninstall the backup software and reinstall it. C. Install a new IDE cable. D. Replace the tape with a new one.
A. If the tape drive reports errors, the first thing you should do is use the included cleaning tape. You must remove the current tape and insert the cleaning tape; then run through the cleaning process. Finally, replace the original tape to see if it works without the tape drive reporting errors. If there is a problem with the backup software, the backup software usually displays an error, not the tape drive. It is more likely that the tape drive needs a simple cleaning than the backup software needing to be reinstalled. It's more common for a tape drive to use a SCSI cable as opposed to an IDE cable. You don't want to replace the tape because that tape may have information that you need. Try cleaning the drive first, and if the tape has failed, make sure you back up the original data to a new tape.

What Is The Only NASA Asset Named After A Living Person? A. The Colbert Treadmill B. The James Webb Space Telescope C. The Hubble Telescope D. The Ames Research Facility
A. NASA has a long history of naming assets after influential astronomers, scientists, and other individual that have both worked directly for NASA or simply contributed greatly to related fields of study. Most of the time the names are selected from a pool of famous but deceased contributors (most likely in a bid to avoid bruising the egos of the living). The Hubble Telescope is a famous example of this: it was named after Edwin Hubble, a scientist who played a crucial role in establishing the field of extra-galactic astronomy. Hubble died in 1953 and the telescope bearing his name was launched in 1990. The only current exception to this rule is that of the Colbert Treadmill. In 2009 NASA held an online poll to encourage the public to help name the newest module of the International Space Station. Comedian and television host Stephen Colbert urged viewers of his show, The Colbert Report, to write in “Colbert†as their suggested name for the module. Although Colbert ended up being the most popular name in the polls, NASA ultimately declined to use it and instead went with the less popular nomination “Tranquilityâ€. In a nod to Colbert, however, they renamed their new space treadmill the COLBERT (Combined Operational Load Bearing External Resistance Treadmill)â€"making it the only NASA asset that bears the name of a living person.

ARP
Address Resolution Protocol
ASLR
Address Space Layout Randomization a security feature that causes a program’s data locations to be randomly arranged in memory. Before ASLR, a program’s data locations in memory could be predictable, which made attacks on a program much easier. With ASLR, an attacker has to guess the correct location in memory when trying to exploit a vulnerability in a program. An incorrect guess may result in the program crashing, so the attacker won’t be able to try again. This security feature is also used on 32-bit versions of Windows and other operating systems, but it’s much more powerful on 64-bit versions of Windows. A 64-bit system has a much larger address space than a 32-bit system, making ASLR that much more effective.

Advanced host controller interface The Advanced Host Controller Interface (AHCI) is a technical standard defined by Intel that specifies the operation of Serial ATA (SATA) host bus adapters in a non-implementation-specific manner. The specification describes a system memory structure for computer hardware vendors to exchange data between host system memory and attached storage devices. AHCI gives software developers and hardware designers a standard method for detecting, configuring, and programming SATA/AHCI adapters. AHCI is separate from the SATA 3 Gbit/s standard, although it exposes SATA's advanced capabilities (such as hot swapping and native command queuing) such that host systems can utilize them.

Obfuscator
An obfuscator is a program designed to make it difficult to understand or reverse engineer source code. The obfuscator takes the clean human-readable source code the programmer has created and does a thorough job shuffling it around, changing simple variables to confusing ones, and otherwise making it difficult for another person to sit down and read the original clean copy (but all while still maintaining the functionality of the source code). Obfuscators are particularly valuable for interpreted languages (such as JavaScript) where the end user can open and inspect the code; without obfuscation it would be trivially easy for someone to lift the code from any interpreted language source code.

A laptop you are troubleshooting will not display any video through the laptop's screen or through external monitors. What should you replace? A. Inverter B. Video card C. LCD D. Drivers
B. If the laptop can't display on the LCD or on an external monitor, that tells you that the video card is most likely faulty. The laptop would need to be opened to replace this. In some cases, it is integrated inot the motherboard, requiring an entire motherboard replacement. If the inverter fails you would see a dim display, but the external monitor should work fine. If the LCD fails, you would not see anything on the display (which can be aided by using a flashlight) and the external monitor would work fine. If the LCD fails, you would not see anything on the display, but the external monitor again would funcition fine. Incorrect drivers can give a variety of problems such as unattainable maximum resolutions, or a garbled screen. However, the display should show something in that case, and should work fine in Safe Mode, where new drivers could be installed.

A customer reports to you that he can no longer open any .tiff files. What is the most likely cause? A. The .tiff files are corrupted B. File associations have been removed C. There is no photo-editing program available D. File extension is not a commonly used type
B. If users were able to open .tiff files, but can no longer do so, then the most likely cause is that the file associations for .tiff (and possibly .tif) have been removed. Programs such as Photoshop, Fireworks and SnagIt can save and open files with the .tiff and/or .tif extension. When a program such as Photoshop is installed, a file association between that program and .tiff files is automatically created. This can be removed on purpose in the OS, by associating the file type with another program, or inadvertently by installing another program. When the person boes to open the file, a message should display, asking to open the file automatically, or select a program to use to open it. Chances are that multiple .tiff files will not have been corrupted at the same time. If it were one file, that would be a differend story, but that the user cannot open any .tiff files should be an indicator of an application issue. If the person were able to open files previously, then there should still be a photo-editing program such as Photoshop loaded on the computer. .tiff and .tif are common lossless file formats for storing images.

C. Automatic Private IP Addressing (APIPA) is a method of automatically assigning an IP address to a device when no other option is available. If a local address is not assigned and a DHCP server is not available, an IP address will be assigned to a device that allows communication across a local subnet. Although communication outside of the subnet isn't possible, the ability to communicate to some devices is more useful than no communication at all. APIPA addresses are reserved to be between 169.254.1.0 through 169.254.254.255.
Which of the following answers can be the cause of a blue screen error? A. Rogue DHCP server B. Incorrect router configuration C. Bad driver D. Incompatible USB device
C. Bad drivers can be the cause of a stop error or blue screen error (also known as BSOD), for example, if cdrom.sys, the basic CD-ROM system driver file, were to fail during bootup. The CPU and RAM can also cause these errors to occur. The blue screen error affects only the local computer; it is not a netwokwide problem that could be associated wit a rogue DHCP server or incorrect router configuration. An incompatible USB device should not cause a blue screen error, nor should that device's driver. Also, the whole idea of USB is that devices you connect to it are automatically recognized and are generally all compatible. However, the USB driver could be a culprit though it is less common.

If You’ve Received HTTP Status Code 418 It Means The Server Is? A. On the moon. B. Out of bandwidth. C. A Teapot. D. Restricted.
C. HTTP status codes are usually reserved for serious issues like server faults, missing files, and other matters of importance. Thanks to an April Fools’ Day joke in 1998, however, there’s a particularly curious (and entirely nonsensical) HTTP status code devoted to indicating the device contacted is, in fact, a teapot. How did such an odd code come about? On April 1, 1998, the The Internet Society released a tongue-in-cheek network protocol memo through The Internet Engineering Task Force’s Request For Comments (RFC) system. This memo, RFC 2324, entitled Hyper Text Coffee Pot Control Protocol, detailed the HTCPCP protocol, a derivative of HTTP intended for controlling, monitoring, and diagnosing internet connected coffee pots. Among the many codes included in the HTCPCP return/error code schema, there is a code 418 “I’m a teapot†intended to politely inform the recipient that the device they are attempting to brew coffee with is, in fact, a teapot and incapable of producing the coffee they desire. As you can imagine, the error code was never formally added to the HTTP error code schema and, should you actually receive the code, you’ve either encountered a very mischievous web master or an actual internet-enabled brewing machine coded by a tinkerer with a fondness for yesteryear’s April Fools’ Day pranks.

The Design Of Super Mario Bros. Was Heavily Influenced By Which Novel? A. The Great Gatsby B. Dr Jekyll and Mr Hyde C. Alice's Adventures in Wonderland D. Gulliver's Travels
C. The classic video game Super Mario Bros. has more than a few similarities to the iconic novel Alice’s Adventures in Wonderland including magic mushrooms, anthropomorphic animals, mysterious portals and passageways, and an all around sort of suspension of reality as we know it that marks both trips through the game and the novel. The comparison isn’t merely the parlor talk of video game geeks though, as Super Mario Bros. creator Miyamoto himself cited the influence of Alice’s Adventures in Wonderland in an interview with Business Week magazine: It started with a simple idea. I thought: “I wonder what it would be like to have a character that bounces around. And the background should be a clear, blue sky.†I took that idea to a programmer, and we started working on it. Mario ended up being too big, so we shrank him. Then we thought, “What if he can grow and shrink? How would he do that? It would have to be a magic mushroom! Where would a mushroom grow? In a forest.†We thought of giving Mario a girlfriend, and then we started talking about Alice in Wonderland.

FLOPS
FLOPS, or FLoating point Operations Per Second, is a measurement of floating point calculations. This measurement is typically used to reference the performance of super computers as it is a better indicator of the performance and computing power of super computer array than referencing the collective processing power of the array. Thus you’ll frequently hear a super computer discussed in terms like 100 teraflops (100 trillion FLOPS) instead of the speed of the processor like one references when talking about desktop and mobile computers.

If You’ve Received HTTP Status Code 418 It Means The Server Is?
HTTP status codes are usually reserved for serious issues like server faults, missing files, and other matters of importance. Thanks to an April Fools’ Day joke in 1998, however, there’s a particularly curious (and entirely nonsensical) HTTP status code devoted to indicating the device contacted is, in fact, a teapot. How did such an odd code come about? On April 1, 1998, the The Internet Society released a tongue-in-cheek network protocol memo through The Internet Engineering Task Force’s Request For Comments (RFC) system. This memo, RFC 2324, entitled Hyper Text Coffee Pot Control Protocol, detailed the HTCPCP protocol, a derivative of HTTP intended for controlling, monitoring, and diagnosing internet connected coffee pots. Among the many codes included in the HTCPCP return/error code schema, there is a code 418 “I’m a teapot†intended to politely inform the recipient that the device they are attempting to brew coffee with is, in fact, a teapot and incapable of producing the coffee they desire. As you can imagine, the error code was never formally added to the HTTP error code schema and, should you actually receive the code, you’ve either encountered a very mischievous web master or an actual internet-enabled brewing machine coded by a tinkerer with a fondness for yesteryear’s April Fools’ Day pranks.

Progressive video
Progressive video, also known as progressive scanning, is a way of displaying video wherein each line of the video display is drawn in sequence. This is a direct contrast to interlaced video wherein the odd and then even lines are refreshed. Progressive video is more bandwidth-intensive than interlaced video (thus most satellite, cable, and digital broadcasts are sent in 1080i instead of 1080p) but provides a much smoother video. The artifacts commonly present in interlaced video such as combing (where rapid motion onscreen causes the alternating lines of the current refresh to become visible to the viewer like the tines of a comb) are completely eliminated in progressive video. Modern televisions and computer displays are all capable of progressive video display. For a more in-depth look at the difference between progressive and interlaced video scanning, check out What Is the Difference Between 1080p and 1080i?

fread 1. what you must include 2. what it returns and what each parameter means
SYNOPSIS #include <stdio.h> size_t fread(void *restrict buf, size_t size, size_t count, FILE *restrict fp); DESCRIPTION fread attempts to copy, from the file or stream identified by fp, count elements (each of size size) into memory, starting at buf. fread may copy fewer elements than count if an error, or end of file, intervenes. fread also advances the file position indicator (if any) for fp by the number of characters actually read. fread_unlocked is a non-thread-safe version of fread. fread_unlocked may only safely be used within a scope protected by flockfile() (or ftrylockfile()) and funlockfile(). This function may safely be used in a multi-threaded program if and only if they are called while the invoking thread owns the (FILE *) object, as is the case after a successful call to the flockfile() or ftrylockfile() functions. If threads are disabled, then fread_unlocked is equivalent to fread. _fread_r and _fread_unlocked_r are simply reentrant versions of the above that take an additional reentrant structure pointer argument: ptr. RETURNS The result of fread is the number of elements it succeeded in reading.
SLI
Scalable Link Interface (SLI) is a brand name for a multi-GPU solution developed by NVIDIA for linking two or more video cards together to produce a single output. SLI is an application of parallel processing for computer graphics, meant to increase the processing power available for graphics. The name SLI was first used by 3dfx under the full name Scan-Line Interleave, which was introduced to the consumer market in 1998 and used in the Voodoo2 line of video cards. After buying out 3dfx, NVIDIA acquired the technology but did not use it. NVIDIA later reintroduced the SLI name in 2004 and intended for it to be used in modern computer systems based on the PCI Express (PCIe) bus; however, the technology behind the name SLI has changed dramatically.

Shadow Copy
Shadow Copy, also known as Volume Snapshot Service, is a data backup technology included in Microsoft Windows that allows the operating system to take snapshots of the system which include files which are locked or otherwise inaccessible to the user. The service can only be used on NTFS-based disks and interacts with the data at the block level. Shadow Copy is integral to the Windows Backup and System Restore utilities. For a more in depth look at how Shadow Copy works, check out HTG Explains: What are Shadow Copies and How Can I Use Them to Copy or Backup Locked Files?

SMS
Short Message Service (SMS) Short Message Service (SMS), or as most of us call it, texting, is the text messaging component of cellular communication networks. It’s the most widely used communication protocol in the world, with billions of people the world over collectively sending six trillion text messages annually. SMS was first proposed and outlined in the mid 1980s but the first text message wasn’t sent using an SMS gateway until 1992â€"commercial deployment followed a year later in 1993. The text messages were short then and they’re short now, due entirely to the constraints of the messaging systemâ€"text messages cannot exceed 1120 total bits of data. As a result, U.S. Cellular users, whose phones use the GSM 7-bit alphabet, are limited to 160 characters (160 * 7-bit characters = 1120 total bits).

Why do array indices start at 0?
The name of an array is actually a pointer to the first element in the array. Writing myArray[3] tells the compiler to return the element that is 3 away from the starting element of myArray. This explains why arrays are always passed by reference: passing an array is really passing apointer. This also explains why array indices start at 0: the first element of an array is the element that is 0 away from the start of the array.

why declare a function prototype?
a function prototype eliminates the need to place a function definition before all calls to the function. Just as you can't refer to a variable before it has first been defined, you can't call a function before it has been defined. example: void myFirstFunction() { void mySecondFunction() ; // define a prototype for an external function named mySecondFunction mySecondFunction ; // call now call function mySecondFunction from within myFirstFunction. }
Before the compiler encounters a call to a particular function, it must already know the function's return type, the number of parameters it uses, and the type of each parameter, That means that function A cannot call a function that is declared after it within the source code. However there is a statement that will allow a function to call another function that has been defined downstream in the source code. What is that statement called:
a function prototype or optionally a function declaration

ATX
advanced technology extended ATX (Advanced Technology eXtended) is a motherboard form factor specification developed by Intel in 1995 to improve on previous de facto standards like the AT form factor. It was the first major change in desktop computer enclosure, motherboard and power supply design in many years, improving standardization and interchangeability of parts. The specification defines the key mechanical dimensions, mounting point, I/O panel, power and connector interfaces between a computer case, a motherboard and a power supply. With the improvements it offered, including lower costs, ATX overtook AT completely as the default form factor for new systems within a few years. ATX addressed many of the AT form factors annoyances that had frustrated system builders. Other standards for smaller boards (including microATX, FlexATX and mini-ITX) usually keep the basic rear layout but reduce the size of the board and the number of expansion slots. In 2003, Intel announced the BTX standard, intended as a replacement for ATX. As of 2009, the ATX form factor remains a standard for do-it-yourselfers; BTX has however made inroads into pre-made systems. This[clarification needed] was designed to solve the problems in BAT and LPX motherboards.

BTX
balanced technology extended BTX (for Balanced Technology eXtended) is a form factor for motherboards, originally intended to be the replacement for the aging ATX motherboard form factor in late 2004 and early 2005. It was designed to alleviate some of the issues that arose from using newer technologies (which often demand more power and create more heat) on motherboards compliant with the circa-1996 ATX specification. The ATX and BTX standards were both proposed by Intel. However, future development of BTX retail products by Intel was canceled in September 2006 following Intel's decision to refocus on low-power CPUs after suffering scaling and thermal issues with the Pentium 4. The first company to implement BTX was Gateway Inc, followed by Dell and MPC. Apple's Mac Pro utilizes some elements of the BTX design system as well but is not BTX compliant, rather using a proprietary form factor.

fseek
int fseek(FILE *fp, long offset, int whence); NAME fseek, fseeko, _fseek_r, _fseeko_r - set file position SYNOPSIS #include <stdio.h> int fseek(FILE *fp, long offset, int whence); int fseeko(FILE *fp, off_t offset, int whence); int _fseek_r(struct _reent *ptr, FILE *fp, long offset, int whence); int _fseeko_r(struct _reent *ptr, FILE *fp, off_t offset, int whence); DESCRIPTION Objects of type FILE can have a ``position'' that records how much of the file your program has already read. Many of the stdio functions depend on this position, and many change it as a side effect. You can use fseek/fseeko to set the position for the file identified by fp. The value of offset determines the new position, in one of three ways selected by the value of whence (defined as macros in `stdio.h'): SEEK_SET---offset is the absolute file position (an offset from the beginning of the file) desired. offset must be positive. SEEK_CUR---offset is relative to the current file position. offset can meaningfully be either positive or negative. SEEK_END---offset is relative to the current end of file. offset can meaningfully be either positive (to increase the size of the file) or negative. See ftell/ftello to determine the current file position. RETURNS fseek/fseeko return 0 when successful. On failure, the result is EOF. The reason for failure is indicated in errno: either ESPIPE (the stream identified by fp doesn't support repositioning) or EINVAL (invalid file position).

itegral floating void Integral types are capable of handling whole numers. Floating types are cabable of specifying values that may have fractional parts. The void type describes an empty set of values. No variable of type void can be specified -- it is used primarily to delare functions that return no values or to declare generic pointers to untyped or arbitraily typed data.

ftell
long ftell(FILE *fp); off_t ftello(FILE *fp); long _ftell_r(struct _reent *ptr, FILE *fp); off_t _ftello_r(struct _reent *ptr, FILE *fp); DESCRIPTION Objects of type FILE can have a ``position'' that records how much of the file your program has already read. Many of the stdio functions depend on this position, and many change it as a side effect. The result of ftell/ftello is the current position for a file identified by fp. If you record this result, you can later use it with fseek/fseeko to return the file to this position. The difference between ftell and ftello is that ftell returns long and ftello returns off_t. In the current implementation, ftell/ftello simply uses a character count to represent the file position; this is the same number that would be recorded by fgetpos. RETURNS ftell/ftello return the file position, if possible. If they cannot do this, they return -1L. Failure occurs on streams that do not support positioning; the global errno indicates this condition with the value ESPIPE.

Name the three sections and what they designate:
main.o : main.c gcc -c main.c Anyway, in this example rule there are three parts: The target, the dependencies, and the commands (well, command). The target is the thing that we want to make. In this case, we want to make the file main.o. Next, after the target (and the colon, which separates targets from dependencies), we list the depenencies - the files that the target depends on. In this case, main.o needs to be rebuilt whenever main.c changes, so we list main.c as a dependency. The last part of the rule is the command that make should run in order to make the target from the depenencies. In this case, we list the gcc command to compile main.c into main.o. Note that you may list as many commands as required, as long as you don't leave a blank line and all commands start with a tab.

NAC
network access control When a computer connects to a computer network, it is not permitted to access anything unless it complies with a business defined policy; including anti-virus protection level, system update level and configuration. While the computer is being checked by a pre-installed software agent, it can only access resources that can remediate (resolve or update) any issues. Once the policy is met, the computer is able to access network resources and the Internet, within the policies defined within the NAC system. NAC is mainly used for endpoint health checks, but it is often tied to Role based Access. Access to the network will be given according to profile of the person and the results of a posture/health check. For example, in an enterprise, the HR department could access only HR department files if both the role and the endpoint meets anti-virus minimums.

What does namespace mean in C++?
std is an abbreviation of standard. std is the standard namespace. cout, cin and a lot of other things are defined in it. ( This means that one way to call them is by using std::cout and std::cin.) The keyword using technically means, use this whenever you can.Sep 3, 2011
What are differences in functioning between following two programs? a) int main(void) {
string s; while(getline(cin, s)) { cout << s << '|' << s.size() << endl; } } b) int main(void) { string s; while(cin >> s) { cout << s << '|' << s.size() << endl; } } Program a) writes everything from input except for newlines, Program b) ignores leading and trailing whilespaces when reading characters from input.
What are the values in the following variables? string str1[10]; int str2[10]; int main() {
string str3[10]; int str4[10]; } "str1 - empty string """" str2 - ten zeros str3 - empty string """" str4 - ten indetermined values"
How to initialize and declare a point struct (in one statement)
struct point p={10,20};
How to define a new datatype that represents a point
struct twovar { int one; int two; };
Given that two int variables, total and amount , have been declared, write a sequence of statements that: initializes total to 0 reads three values into amount , one at a time. After each value is read in to amount , it is added to the value in total (that is, total is incremented by the value in amount ).
total = 0 ; for ( int i = 1 ; i <=3 ; i++ ) { cin >> amount ; total += amount ; }
what does the following code do
total = 0 ; k = 1 ; do { total += k * k ; k++; } while ( k <= 50 ) ; it compute the sum of the squares of the first 50 counting numbers, and store the value in total . it puts 1*1 + 2*2 + 3*3 +... + 49*49 + 50*50 into total.
