- 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?)
- Archie: Search tool used to find resources
stored on Internet-based FTP servers.
- ASCII: It stands for American Standard Code Information Exchange. This
is text. It's 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 ones and zeros. 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.
- ASP: Active Server Pages.
A Web development language from Microsoft that runs
on their server software.
- AVI: Stands for Audio/Video Interleaved. Microsoft's format for encoding
video & audio for digital transmission.
- 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 connect with 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 U.S. 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
measured 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 the 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.
- BBS: Stands for Bulletin Board Service.
- BIOS: Stands for Basic Input/Output System. This is the little set of programs
that lets 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 as a number,
a 1 or a 0 to be exact. A grouping of bits helps 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.
- Browser: User's software program for viewing
& browsing information on the Internet.
- 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 by 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've been displayed and saved.
- 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.
- Client: A computer attached to an Internet
server.
- COBOL: Stands for Common Business Oriented Language.
- COM: Stands for Component Object Module.
- Compiler: This is an application that converts
a programming language into a 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 makes sure every part of the computer is working
together to present the information).
- CSS: Stands for Cascading Style Sheets.
- 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 the entire 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.
- Data Rate: Speed that information moves
from one item to another. This is usually in the form
of bits.
- 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.
- DHTML: Stands for Dynamic HTML.
- 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 playing 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 nonetheless.
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. "dynamicpage.com" is our domain. Click here if you want one of your own!
- 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 in another computer. Example:
If you log in to 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's a terminal, but it's just watching -- thus a
dumb terminal.
- EBCDIC: Extended Binary Coded Decimal Interchange Code. It
is also called the Extended ASCII Code, as it adds
an eighth digit to the normal seven-digit code.
- E-Mail: Stands for Electronic Mail.
E-mail is actually a method of transferring files
among computers, rather than the file itself, but
that's what the name has come to mean.
- Encryption: This is any one of many methods
to transfer a file into a hard-to-crack code. It is
often done by scrambling or by letter-to-letter replacement.
- Engine (as in "Search Engine"): This is
the working part of a database or application.
- Ethernet This is a method of file transfer
that uses dedicated cables rather than dial up phone
lines. Ethernets are usually set up attaching end
users to a central system like an Intranet. It was
invented by Xerox believe it or not.
- FAT Stands for File Allocation Table. Basically
this is a table of contents in a directory that tells
the computer what al is in there. Look at your Netscape
cache, you'll see a FAT. It'll be the first file.
- FAQ Stands for Frequently Asked Questions.
An FAQ is a file or document where a moderator or
administrator will post commonly asked questions and
their answers.
- Fiber-Optic This is a new style of cable
being used for very high speed data transmission.
It works by pushing (modulating) a light wave across
cable. The data is carried along with the light.
- File Sharing This is the most important
feature of the Internet. This is a method of allowing
one server to give the same file to many different
end users.
- FORTRAN Stands for FORmula TRANslation.
- Freeware This a shortened version of Free
Software. Programmers offer their work without wanting
pay in return.
- FTP Stands for File Transfer Protocol.
- Gateway As in Common Gateway Interface (CGI).
It is a piece of software that allows two items to
communicate with each other. They are used to make
connections between computers and systems inside that
computer.
- GIF Pronounced "jif." Stands for Graphical
Interchange Format. It is an image format created
by Compuserve.
- Gigabyte (GB) It's about a billion bytes.
Actually it's 2 to the 30th power or 1,073,741,824.
- GIGO It's an acronym that stands for Garbage
In, Garbage Out.
- Gopher One of the first commonly used interfaces
for the Internet with a format structure and resource
for providing information. It was created at the University
of Minnesota who's mascot is the gopher.
- GUI Pronounced "gooey". It stands for Graphical
User Interface. It's the graphical representations
you see on the screen.
- Hardware These are the physical items including
your computer and floppy discs.
- Helper Application This is an application
your browser uses to manipulate a downloaded program.
- Hotlist List of URLs saved within the Mosaic
Web browser. (Bookmark in Netscape.)
- HTML Stands for HyperText Markup Language.
Common language used to write documents on World Wide
Web.
- HTTP Stands for HyperText Transport Protocol.
Common protocol used to communicate between World
Wide Web Servers.
- Hypertext This is a mark-up language that
allows for non-linear transfers of data. The method
allows your computer to provide the computational
power rather than attaching to a mainframe and waiting
for it to do the work for you.
- IBM Stands for International Business Machines
- Icon A small video display that acts as
an activation link when clicked on.
- Interface This is any type of point where
two different things come together. Most often, the
term is used to describe the programs between you
and your computer like Windows, OS/2 and others. What
you see on the screen is the interface between you
and what your computer is doing.
- IS Stands for Information System.
- ISO Stands for the International Standards
Organization. Someone has to say what is the standard
for transferring data. These people are it. You'll
find them in Paris.
