Cisc

(Complex instruction set comp technology)

Utility SW

A type of System SW that helps you moniter, and configure settings for your digital gear, its OS or app software.

Differential Backup

Makes a backup of only files that were added or changed since last full Backup session

RISC(Reduced instruction set comp)

Performs more intructions faster than a CISC processor. It might require more of these simple instructions

Boot Process

The sequence of events that occurs between the time you turn on your comp and the time it is ready for issue commands.

Memory

WHat is the area of a comp that temporarily holds data waiting to be processed, stored or output

Byte

What is a group of 8 bits called?

Computer

What is a multipurpose device that accepts input, processes data, stores data and produces output

bit

What is an abrivation for binary?

Storage

What is the area where data can be left on a permanent basis when it is not immediately needed for processing?

Internet Access

What was the biggest reason for a sudden rise in computer ownership?

Web Bug

a clear Gif that is a 1x1 graphic embedded in a web page. designed to track whos reading the page or email

Resource Fork

a companion to a data fork. Stores info about the data in the data fork, such as file type and the app that created it.

LAN Network

a dat communications NW that connects PC's within a geographical area.

Watermarks

a patern of bits inserted at varied place in an image or context stream that can be used to trade or control content

MAN network

a public high speed network capable of a 50 mile range

Application SW

a set of comp programs that help a person carry out a task

Solid State Storage

a technology that stores data in erasable, rewritable circuitry. Rather than spinning disks. Used on iPods, cameras, portable media players, iPads, and cell phones

RAM

a temp holding area for data, app program instructions and the OS

ROM (read only memory)

a type of memory cicuitry that holds the comp's startup routine. ___ bias sends instructions to RAM to begin taking instructions

MAC(Media access control)

a unique number assigned to a network interface card when it is manufactured

Phishing

an email scam thats designed to persuade you to reveal confidential info

Pharming

an exploit that redirects users to a fake sites by poisoning a domain nam server with fake IP. more sophisticated than Phishing

Incremental Backup

back up files that were added or changed sinc ethe last backup, not files that were changed.

bitmap

composed of a grid of dots. the color of each dot is a stored as a binary number. Each pixel is assigned a number

WAN Network

covers a geographical area and consists of a smaller NW,

System Software

helps the comp system monitor itself in order to func. efficiently

Vector graphic

instead of storing the color value for each pixel. a vector contains instructions the comp needs shape, size, position and color for each obj.

executable file

it is designed to be started by users or automatically launched by the OS. A primary set of instructions for the comp to execute.

Concurrent License

priced per copy, and allows a specific number of copies to be used.

loseless compression

provides the mean to compress a file then reconstitute all the data into a its original slate.

Cookie

small chunk of data genreated by a webserver and stored in a text file on your comp

HTTP

the protocol that works with TCP/IP to get web resouces on your Desktop. Web resouce= any chunk of data that has a URL

Statistic IP

the same IP address always. Use when hosting a website or email service.

BAndwidth

the transmission capacity of a communications channel

lossy compression

throws away some of the data during the compression process.

Tracing SW

used to convert bitmap to vectors

Rasterization

used to convert vectors to bitmap

Port PRobe

used to look for comps with open communication ports

PAN network

used to refer to the interconnection of a personal digital devices wirelessly

Benchmarks

what are the results of the speed of a microprocessor that is posted online.

Image Quality

what is affected by screen size, dot pitch, width of viewing angle, response rate, and color depth
