Look for sites that offer several sets of facts, or consider opinions from several sources. Relevance: Is the information in the site current? Material can last a long time on the web. Some research projects (such as historical accounts) depend on older records. However, if you're writing about cutting-edge technologies, you need to look for the most recent sources. Therefore, look for a date on information to make sure it is current. Audience: For what audience is the site intended? Ensure that the content, tone, and style of the site match your needs. You probably wouldn't want to use information from a site geared toward teens if you're writing for adults, nor would you use a site that has a casual style and tone for serious research. Links: Are the links available and appropriate? Check out the links provided on the site to determine whether they are still working and appropriate for your needs. Don't assume that the links provided are the only additional sources of information. Investigate other sites on your topic as well. You should also be able to find the same information on at least three websites to help verify the information is accurate.

For example, in the following sentence, you can easily see the repeated patterns of letters: The rain in spain falls mainly on the plain. Although in this example there are obvious repeated patterns (ain and the), in a large document, the repeated patterns may be more complex. The compression program's algorithm therefore runs through the file several times to determine the optimal repeated patterns to use to obtain the greatest compression. Current compression programs can reduce text files by as much as 50 percent.

What are Computer-aided design (CAD) programs?

Computer-aided design (CAD) programs are a form of 3D modeling engineers use to create automated designs, technical drawings, and model visualizations. With CAD software, architects "build" virtual models of their plans and visualize all aspects of design prior to actual construction. The 3D nature of these programs allows engineers to rotate the model and make adjustments to their designs where necessary. For example, the medical engineering community uses CAD to create anatomically accurate solid models of the human anatomy to develop medical implants. The list of CAD applications keeps growing as more and more industries realize the benefits CAD can bring to development and manufacturing.

What are logical ports?

Computers have logical ports, which are like windows and doors in a house. They allow a computer to organize requests for information from other networks or computers. These ports are numbered and assigned to specific services. For example, e-mail messages are sent through logical port number 25. Open logical ports, like open windows in a home, invite intruders. Unless you take precautions to restrict access to your logical ports, other people on the Internet may be able to access your computer through them. A firewall is the best means of protection.

The first part of a file, or the file name, is the name you give the file when you save it. For example, "bioreport" may be the name of a report for your biology class. In Windows, following the file name and after the dot (.) comes a three- or four-letter extension, or file type. Here you see some common file extensions and the types of documents they indicate. The extension identifies what kind of file it is and what application should be used to open the file. For example, if the "bioreport" file is a Word document, it will have a .docx extension and be named "bioreport.docx".

What is the URL domain name?

The first part of the domain name indicates who the site's host is. The domain name's three-letter suffix (such as .com or .edu) is called the top-level domain (TLD).

Tips for using open source, freeware, and beta versions of software safely:

Only use programs that are designed to work with your operating system. You can crash your system and may need to reinstall your OS if you load a program that wasn't written for your OS. Wait until the last version is released when using beta versions. By that time, most of the serious bugs have been worked out. Stick with reliable developers whose software you are familiar with. You should be comfortable with the reliability of the source of software before downloading a freeware or beta version. That way, you can be more certain that a serious bug or virus is not hiding in the software. Make sure that your virus protection software is up to date. Downloading software from an unknown source can put your system at risk for a virus. Before installing software, create a restore point. That way, if anything goes wrong during installation, you can always restore your system back to how it was before you started.

But how will a firewall help if I'm not exchanging any valuable information over the Internet and don't have any important files on my computer? 1.A firewall protects your computer by blocking all the logical ports that allow data to come in. As long as you send and receive attachments over e-mail, you need a firewall. 2.A firewall protects your computer by screening data coming into the logical ports and confirming whether it's from a trusted source. Even if you don't store proprietary files on your computer, a hacker can steal personal information from your computer to commit identity theft. 3.A firewall protects your computer by blocking off access to all physical ports or communications gateways to the computer. It is in essence a packet filtering device that prevents hacker intrusion. 4.A firewall protects your computer by blocking access to all logical and physical ports.

2 (A firewall protects a computer by screening data coming into its logical ports to confirm whether it's from a trusted source. You need a firewall as hackers can commit identity thefts. Using packet sniffers, hackers "sniff" the packets travelling the Internet, capture valuable content, and sell or use the content illegally.)

Once the BIOS program is activated, what happens next? 1.The BIOS loads the operating system into RAM. 2.The BIOS makes sure that all your computer's peripheral devices are attached and working. 3.The BIOS verifies your login name and password. 4.The BIOS checks the kernel is loaded.

2 (After BIOS is activated, it checks that all attached devices are in place and working. It also checks to see whether the video card and video memory are responding correctly. This test is called a power-on self test, or POST. The BIOS then compares the results of the POST with the hardware configurations stored in CMOS, a special kind of memory that uses almost no power and is never erased. If the results of the POST match the configurations stored in CMOS, the boot process continues.)

If my Microsoft Excel file is all garbled, could it have a virus? 1.It sounds like you definitely have a virus. You need to run antivirus software. 2.It sounds like it could be a virus, but it could also be another problem, such as a corrupt file. You should try to open other files in Excel first. 3.It sounds like your Excel application itself is corrupt. You should try to reinstall Excel. 4.Try to open your Excel file in a previous version of Excel. If it won't open, it is a virus.

2 (Although the symptoms you describe sound like a virus infection, they might actually be caused by another problem, such as a corrupted file. Try to open another file in Excel. If that opens up fine, it means that your file is corrupt. If not, your Excel application itself may be corrupt and should be reinstalled. It's a good idea to run antivirus software too and rule out virus infection.)

5) What happens after the POST? 1.After POST, BIOS copies the operating system from ROM to the hard drive. 2.After POST, BIOS copies the operating system from the hard drive to RAM. 3.After POST, BIOS copies the operating system from the hard drive to the ROM. 4.After POST, BIOS performs the authentication process.

2 (BIOS loads the OS from its permanent storage location on the hard drive to RAM. Once the OS files are loaded into RAM, the kernel is loaded.)

Is web page-authoring software the same type of software I would use if I wanted to design a brochure or newsletter? 1.Yes, you can easily use web page-authoring programs to design newsletters and brochures. 2.Actually, to design newsletters and brochures, you would need special software, such as Adobe InDesign. 3.Actually, you need special graphics software, like Adobe Premiere, to design newsletters and brochures. 4.Actually, Peachtree is the best software for designing newsletters and brochures.

2 (Desktop publishing programs such as Adobe InDesign offer a variety of tools with which you can format text and graphics and design and lay out complex publications. Also note that some word-processing programs allow you to lay out simple brochures and newsletters.)

Once I download or buy the firewall software, how do I get it installed and tested? 1.You need a software programmer to create a special drive to install the firewall and use the Error-Check utility. It will check for any errors in the firewall tests and you can proceed accordingly.​ 2.Some people prefer professional help, but most home users can install and test their firewall by following the instructions provided in the user manual. You can test it by going to such sites as grc.com and running the ShieldsUP test to see if you're safe. 3.Just call the local technician. Do not try to install it on your own. It will cause system problems. You can test it on your own though, because all firewalls come with testing software.​ 4.You can install the firewall on your own but testing requires a certified professional or you will have a hard drive crash.​

2 (Firewalls can be easily installed. Some people prefer professional help, but most home users can install and test their firewall by following the instructions provided in the user manual. You can test the firewall on your own with the help of a testing agent such as ShieldsUP! It is available at www.grc.com.​)

What is the boot process? 1.The boot process ensures that the operating system is loaded into ROM. 2.The boot process ensures that the operating system is loaded into RAM. 3.The boot process ensures that the operating system is loaded onto the hard drive. 4.The boot process ensures that the operating system is loaded into the kernel.

2 (The boot process is the process that occurs when you start your computer. It involves four main steps, the outcome of which is that the operating system is loaded into RAM from its permanent storage location on the hard drive.)

What is the kernel? 1.The kernel is the essential component of the OS. It manages the ROM. 2.The kernel is the essential component of the OS. It manages the processor and all other components of the system. 3.The kernel is the essential component of the OS. It manages the configuration of peripherals. 4.The kernel verifies your login name and password.

2 (The kernel is the essential component of the OS that manages the processor and all other components of the system. Because it stays in RAM the entire time your computer is powered on, the kernel is called memory resident. Other parts of the OS that are less critical stay on the hard drive and are copied over to RAM on an as-needed basis. These programs are called nonresident.)

2 (Web page-authoring software such as Adobe Dreamweaver allow even novice users to design interesting and interactive web pages, without knowing any HTML code. Note, too that if you need to produce only the occasional simple web page, many software applications such as Microsoft Office include features that enable you to convert your document easily into a web page.)

Do I face any risks when I install or download beta versions and freeware from the Internet? 1.Freeware contains up-to-date virus protection, and beta products are generally developed by reliable developers. As such, there aren't really any risks. 2.You must exercise caution when downloading freeware and beta versions as they may contain bug or viruses. 3.Freeware is associated with the risk of bugs or viruses, whereas beta products have built-in virus protection and are generally developed by reliable developers. Hence, it's important that you exercise caution with freeware. 4.The whole concept of freeware and beta versions assumes ethics and therefore they are thoroughly safe.

2 (You must exercise caution when downloading freeware and beta versions as they may contain bugs or viruses. This is because beta products may not be from a reliable developer so are not always bug free. As a result, you run the risk of something going awry with your system when using them. Loading freeware programs that are not written for your computer's operating system can also crash your system and may force you to reinstall your operating system.)

7) Sometimes an address looks like www.nytimes.com and at other times like www.nytimes.com/pages/cartoons. What do the parts after .com indicate? 1.Actually, both these addresses mean that you are requesting a site's home page. These will connect you to the home page or main page of the website. 2.When you connect using only the domain name, such as in the first example, you can visit only the home page of the website and cannot move around the site. When there is additional information after the slash, you can visit the home page but can also move all around the site. 3.The difference is that when the URL is only the domain name, you are requesting a site's home page. When there is additional information after the slash, it indicates a particular file or path within the site. ​ 4.Actually, both of these addresses mean that you are requesting a site's subdirectory.

What exactly is a virus? 1.A computer virus is a computer program that appears to be something useful or desirable (like a game or a screensaver), but at the same time does something malicious in the background without your knowledge, such as destroying your files. 2.A computer virus is a computer program that looks at packets as they travel on the Internet and infects them with debilitating code. 3.A computer virus is a computer program that attaches itself to another computer program and attempts to spread itself to other computers when files are exchanged. 4.A computer virus is a computer program deployed by hackers that looks at each packet as it travels on the Internet.

3 (A computer virus is a program that attaches itself to another program and attempts to spread to other computers when files are exchanged. Virus symptoms include icons or files disappearing, browser changes, and odd images appearing and sounds playing. A virus may also be one cause of data files becoming corrupt or programs not working.)

So, am I all set after I have the antivirus software up and running? 1.Yes. You are all set and can use your computer without fear of infection from viruses or worms. 2.Not really. You need to make sure you update your application software regularly. 3.Not really. You need to keep both your antivirus software and your system software up-to-date. 4.Not really. You need to update your application and system software.

3 (Antivirus software catches only known viruses. Unfortunately, new viruses are written all the time. To minimize the risk of your computer being attacked by a new virus your software can't detect, you need to keep your antivirus software up-to-date. In addition, many viruses are created to exploit weaknesses in operating systems. To combat these threats, make sure your OS is up-to-date and contains the latest security patches (or fixes) that software manufacturers provide.)

What else can hackers do? 1.Hackers can also launch an attack from your computer called a denial-of-service (DoS) attack. A DoS attack is an attack on your Disk Operating System. It enables the hacker to gain control of your OS by which he can create problems in the files stored in your unprotected computer. 2.Hackers can also launch an attack from your computer called a denial-of-service (DoS) attack. A DoS attack is actually a virus that attacks the hard drive, corrupting the files stored in your computer. 3.Hackers can also launch an attack from your computer called a denial of service (DoS) attack. A DoS attack is an attack on a computer system launched from an unprotected computer. 4.Hackers can also launch an attack from your computer called a denial-of-service (DoS) attack. A DoS attack is when the hacker uses your personal information for the purpose of defrauding you.

3 (In a denial-of-service (DoS) attack, a hacker makes repeated requests of a system through a zombie, a computer that the hacker has taken over. A computer can handle only limited requests for information at a time. On being flooded with requests in a DoS attack, the system shuts down, denying access to legitimate users. Some hackers launch distributed denial-of-service (DDoS) attacks, which are attacks launched from more than one zombie at the same time and are harder to stop.)

How do logic bombs and worms work? 1.Logic bombs execute when a certain set of conditions is met and spread when infected files are passed from user to user, whereas worms infect a host file and wait for you to execute that file before they spread. 2.Logic bombs run independently of host file execution and are much more active in spreading themselves, whereas worms infect a host file and wait for you to execute that file before they spread. 3.Logic bombs execute when a certain set of conditions is met and are spread when infected files are passed from user to user, whereas worms run independently of host file execution and are much more active in spreading themselves. 4.Logic bombs replicate themselves to a hard drive's master boot record, whereas worms run independently of host file execution and are much more active in spreading themselves.

3 (Logic bombs execute when a certain set of conditions is met, such as starting a program a certain number of times, and can even reformat your hard drive. Logic bombs are spread when infected files are passed from user to user. Unlike viruses, worms run independently of host file execution and are much more active in spreading themselves. This causes problems as the volume of e-mail traffic and network activity generated by worms attempting to spread can bring networks to a halt.)

What are logical ports? 1.A logical port is an external port that allows you to transfer data and make requests from other computers. 2.A logical port is like a filter fitted to your computer. The logical port checks to be sure that any information that you send or receive is logically acceptable. If it's not, it is rejected by the logical port. 3.A logical port is a virtual communications gateway that allows a computer to organize requests for information from other networks or computers. 4.A logical port is a large group of software programs that runs autonomously on zombie computers.

3 (Logical ports are virtual, not physical, communications gateways that allow a computer to organize requests for information from other networks or computers. Logical ports are numbered and assigned to specific services. For example, e-mails are sent through logical port 25. Open logical ports invite intruders. If you don't restrict access to your logical ports, hackers can access your computer through them.)

Is it important to have a firewall on a home network? 1.If you're using a dial-up Internet connection, you don't need a firewall. 2.You need it only if you're going to buy things online with a credit card. If not, you can do without a firewall. 3.To be safe, you should always have a firewall if you plan to connect to the Internet. 4.Hackers don't bother home computers.

3 (Regardless of whether you have a broadband or dial-up Internet connection, to protect your home network from hackers, you need a firewall.)

And what are scripts? 1.Scripts are programs or files you download off the web. Once executed, they perform their malicious duties in the background, often invisible to the user. 2.Scripts are programs that seem to be screensavers but actually perform other activities that can harm your computer in the background. 3.Scripts are mini programs that are executed without your knowledge when you enter a site. 4.Scripts are changes in its own code that avoid detection.

3 (Scripts are small programs, hidden in websites, which are executed without your knowledge when you enter a site. They are often used to perform legitimate functions on websites, such as collecting name and address information. However, some scripts are malicious and can infect your computer with a virus.)

How can my computer catch a virus? 1.One way your computer can get a virus is when too many people use the same computer. 2.One way your computer can get a virus is by booting it with an unformatted DVD in the DVD drive. 3.One way your computer can get a virus is by booting it with an infected flash drive left in a USB port. 4.One way your computer can get a virus is by running antivirus programs.

3 (Your computer can get a virus by booting up your computer with an infected flash drive left in a USB port. Such boot-sector viruses are commonly found on infected disks and replicate themselves into the hard drive's master boot record (a program that executes whenever a PC boots up). This ensures that the virus is loaded into the PC immediately. Other viruses include macro, time bombs, e-mail viruses, logic bombs, scripts, encryption viruses, and worms.)

I've heard some friends talking about software that they got for free. Can you tell me more about free software? 1. Software you can use for free is called freeware or beta ware, but it prevents you from using the product once the initial trial period is over. 2. You can use freeware, which is software that can be used free for a limited time. Alpha versions, software still under development, are also available for free. 3. You can use freeware, software that is available for free, and beta versions, free software that is still under development. 4. Copyleft is the only free software.

3. (Freeware is copyrighted software that you can use for free. Some software developers offer beta versions of their software—that is, versions that are still under development—free of charge to users so that errors or bugs can be reported before the software is commercially released.)

2) Do I have a choice in browsers? 1.Microsoft Edge is the default browser for home computers and is the most reliable browser in use today. 2.Although there are other choices, they are very expensive. 3.Microsoft Edge is the most used browser on the market and there are no others. 4.There are other choices to using Microsoft Edge, including Firefox and Safari, and Google Chrome.

How do you resolve errors in the boot process?

Sometimes problems occur during the boot process. Here are some suggestions for solving a boot problem: If you've recently installed new software or hardware, try uninstalling it. (Make sure you use the Uninstall a program feature in the Control Panel to remove the software.) If the problem no longer occurs when rebooting, you can try reinstalling the device or software. Try accessing the Windows Advanced Options Menu. If Windows detects a problem in the boot process, it will add Last Known Good Configuration to the Windows Advanced Options Menu. Every time your computer boots successfully, a configuration of the boot process is saved. When you choose to boot with the Last Known Good Configuration, the OS starts your computer by using the registry information that was saved during the last shut down. If you are running Windows 10, you can also try resetting your computer. Reset your PC attempts to diagnose and fix errors in your Windows system files that are causing your computer to behave improperly.

What are all the steps to the boot process?

Step 1: The CPU activates the basic input/output system (BIOS). The BIOS is located on a ROM chip. Data stored in ROM does not get erased when the computer is turned off.​ Step 2: BIOS checks that all attached devices are in place and working and that the video card and memory are responding correctly. This test is called a power-on self-test (POST). If the results of the POST are OK, the boot process continues. Step 3: BIOS goes through a preconfigured list of devices in its search for the drive that contains the system files. When located, the operating system loads into RAM from its permanent storage location on the hard drive. Step 4: The registry is checked for further configurations and customizations. If the entire system is checked out and loaded properly, the desktop appears on your screen. The computer system is now ready to accept your first command.
