Glossary of Computer / Internet Terms

32-bit/16-bit This denotes the number of "pieces" (or bits) of information required by an operating system to run a certain application. It also deals with the construction of the computer's CPU (Central Processing Unit) or brain. The Pentium CPU easily runs 32 bit applications because the wires that hold all the pieces together (known as "busses") are big enough to flow through 32 bits at a time. 486s, 386s and below aren't big enough. They work with 16 bits at a time. Windows95 is a 32-bit application. Yes, it will run on a 486, but very slowly while using a great deal of memory and virtual memory (hard drive space) to do it.
ANSI It stands for American National Standards Institute. This is the place that sets standards for data communications, like the Internet.
Analog Not digital. This is data in the form of a continuous flow. A record or a tape is analog. Digital on the other hand is in pieces, or samples. More to come on that.
AppleShare This is Apple Computer's network system. It allows many different end users (people on computers) to attach to one central location and get files. (sound familiar?)
Application This is a program. It does things when called upon. A shortened version gave Java it's name: applet.
ASCII It stands for American Standard Code Information Exchange. This is text. Its all those things you see on your keyboard. However, it is standardized text so data transfer is allowed between systems. It works by representing letters and characters through a seven digit code of one's and zero's. An example would be that "Joe" might look like this to the computer: 0011010,0111100,01010011.
Asynchronous Transferring data with the help of start and stop bits that indicate the beginning and end of each character being sent.
Backbone Well, all of these computers have to come together somewhere. There are many "backbones" on the internet. Think of the backbone as the next larger grouping of computers you attach to to get included in the web. You're at the end of a rib coming off of the backbone-get the picture? The main backbone of the Internet here in the US is the NSFNet. It stands for National Science Foundation Net.
Bandwidth The carrying capacity of a wire attached from one computer to another. It is usually measures in the amount of bits carried. You know that 28.8 modem you have? It will allow a bandwidth of 28,800 bits per second.
Baud This is a measurement of amount of data that can be transferred in one second. Example: A 14.4 baud modem can transfer 14,400 bits of information in one second.
BIOS Stands for Basic Input/Output System. This is the little set of programs that let all the different parts of the computer talk to each other.
Binary This is a basic system of numbering using ones and zeros.
Bit/s "Bit" is a grouping of the words "binary" and "digits." Think of a bit a number, a 1 or a 0 to be exact. A grouping of bits help to make up ASCII Code. Data transfer is often in terms of the number of these "bits" that can be moved in a second.
BMP Pronounced "bimp." It's a bitmap, an image made up of little dots.
Buffer The buffer is a section of the computer where data is stored before being used. This buffering allows time for an application to fix differences in bit rates among other things. It creates a space of time for compensation.
Burst Most people know this from "pipeline burst cache". Burst means to send data in a large package all at one time rather than small bits over a longer time.
Bus There are wires between all the parts of your computer. There is a wire from the memory to the brain, and from the brain to the printer, etc, etc. Those wires are called busses. They differ from one another due to the amount of data they will transfer at one time.
Byte A unit of space. It is also used to represent a series of seven or eight ascii code digits representing a character.
C A programming language developed at AT&T.
Cache This is a memory section that holds data while the CPU (central processing unit) or brain, is working on it. Go to your Netscape directory - you'll see a cache full of files marked ".moz". Those are "mozilla" files. That's what Netscape calls pages after they display and save them.
CD-ROM Compact Disc - Read Only Memory. It's a storage place that disallows recording or manipulating of its data.
CGA Stands for Color Graphics Adapter. It's a piece of hardware that plays with colors.
COBOL Stands for Common Business Oriented Language.
COM Stands for Component Object Module.
Compiler This is an application that converts a programming language into machine language program.
CPU Stands for Central Processing Unit. This is the brain of your computer. It is made up of two parts: The Arithmetic Logic Unit (this does all the processing) and the Control Unit (this make sure every part of the computer is working together to present the information).
Client A computer attached to an internet server.
Cyberspace This is a term that gives us a way to sort of "see" what we are surfing while on the net. It's a generic term for all of the Internet, not just the World Wide Web.
Data Anything that is recorded or used for processing. The stuff that transfers between computers needed a name - Data seemed good.
Database Anything that accepts data is a database. A pile of newspapers is a database. A computer database has the ability to manipulate that data. It is possible to attach applications to that database to search the contents.

DDS Stands for Direct Digital Signal.
Dedicated Line This is a phone line meant specifically for one thing, like being attached to a computer.
Demodulation This is the process of converting analog information (like over phone lines) into digital information (like in a computer). See "Modem" for more.
Dial-Up Line This is a telephone line that is connected to a server. When it is called, tones are exchanged between the server and the devise calling in order to attach.
Digital Your CD player is digital. It is a series of small samples of data play together very quickly (30,000 times a second). Digital recording of information means representing the bits of data through ones and zeros. Playing the bits back to again create what was recorded is called digital processing.
DNS This stands for Domain Name System. The Internet runs by assigning different sites "Names". They are actually 4-part strains of numbers associated with names, but names none the less. Getting a DNS error means that the address you are attempting to reach is not recognized by the Internet community.
Domain This is a higher level section of the Internet, usually given its own DNS. The domain is the section of an address before the directory slashes start. www.htmlgoodies.com is my domain.
DOS Stands for Disc Operating System. It is a generic term for the many programs that accept commands to trip applications to run. The most popular is MS-DOS (MS stands for Microsoft).
DPI Stands for Dots Per Inch
Dumb Terminal This a video screen that is seeing manipulation going on an another computer. Example: If you log into AOL, your computer is not doing the work--AOL's computer is. You are just being offered a window into that world. That window is your screen. It is a terminal, but is just watching--thus a dumb terminal.
