Of Terms for new Internet Users
Applet

interactive functions on a file or Web page.
ADSL

that allows you to access the Internet over standard phone
lines at very high speeds.
Bit
- The smallest piece of digital information understood by
computers.
Bandwidth
- The rate information travels from one place to another either
inside a computer or between computers. Bandwidth is usually
measured in bits per second, kilobits (thousands of bits)
per second, or megabits (millions of bits) per second. A 28.8
modem allows for a connection of 28.8 kilobits per second.
Blocking software
- A computer program that allows parents, teachers, or guardians
to "block" access to certain Web sites and other
information available over the Internet. All blocking software
has filtered the information before blocking access to it.
(See also "filtering software")
Bookmark
- A placeholder for interesting or frequently used Web sites,
so that these sites can be revisited easily without having
to remember or retype the Internet address.
Browser
- A software product that lets you find, see, and hear material
on the World Wide Web, including text, graphics, sound, and
video. Popular browsers are Netscape Navigator and Microsoft
Internet Explorer.
Byte
- Bytes are a basic measurement of computer memory. A byte
is made up of eight bits.

stores information (text, graphics, sounds, etc.) from pages
or sites that you have visited recently so that returning
to those pages or sites is faster and easier.
CD-ROM
- A computer disk that can store large amounts of information;
generally used on computers with CD-ROM drives. "CD-ROM"
stands for "Compact Disk Read Only Memory". That
means it can only play back information, not record or save
material.
Chat -
A feature of online services or Web sites that allows participants
to "talk" by typing messages that everyone can read
at the same time. Here's how it works: The participant enters
the chat room, types a message on his or her computer, and
sends it; and it is instantly displayed on the screens of
the other users in the chat room. Admission is generally not
restricted. You never know who is going to be reading your
messages or responding to them, so it's best to be cautious.
Chat room
- A "place" or page in a Web site or online service
where people can chat, or "talk," with each other
by typing messages. It's "real-time" communication

is delayed communication.
