A device that sends and receives data over a cable television system. Cable
modems can receive data at 500kbps or more -- approximately 10 times faster
than a standard analog modem. Uploads, however, are often limited to 128kbps.

A service in which the call direction is reversed to take advantage of
lower pricing from one end. For example, if a telephone customer in Japan
wants to place a call to a friend in Australia using callback he would
dial his access number in the USA, hang up and wait a few seconds for a
callback from the USA. By calling his access number in the USA and hanging
up, he has triggered his callback company’s switch to call him at his telephone
number in Japan. When he answers his callback he has a USA dial tone, and
is using the USA telephone system to make his call to Australia at low
USA rates. Most callback companies are based in the USA since USA rates
are the lowest in the world. The callback industry was founded by IDT Corp.,
of Hackensack, New Jersey, in 1991. It was recognized and sanctioned as
an industry by the FCC on June 15, 1995. Callback enables customers to
avoid high telephone rates charged in any country. They can also avoid
hotel surcharges on phone calls.

also GSM and wCDMA)
Code division multiple access – a type of mobile phone narrow band technology
based on 900 MHZ radio waves, developed by Qualcomm of san Diego California,
USA, which holds patents on it. The system is used in the USA and in North
America for mobile phones. The system is in competition with GSM – technology,
which sets the standard for mobile phones in Europe, and much of Asia.
Being adopted by China. It is a civilian application of a system originally
developed for military communication. Qualcomm's CDMA is one of a number
of technology standards that have been developed to power the next generation
of handheld devices.
CDMA is a digital spread-spectrum modulation technique Used mainly with
personal communications devices such as mobile phones. CDMA digitizes the
conversation and tags it with a special frequency code. The data is then
scattered across the frequency band in a pseudorandom pattern. The receiving
device is instructed to decipher only the data corresponding to a particular
code to reconstruct the signal.
Early in 2000, China Unicom, China's second-largest telecommunications
provider, signed an agreement to create a national mobile phone network
based on Qualcomm's CDMA technology. Those plans were then cancelled, and
a decision was made to set up a facility to build a CDMA network, but to
let the market determine the future of the CDMA based system.

CD-R (compact disc -- recordable)
An optical storage technology that encodes data on a laminated metallic
disc. Also a blank compact disc Used to record audio or data files. You
cannot edit, erase or rerecord a Used CD-R.
disc -- read-only memory)
An optical storage technology that encodes data on a laminated metallic
disc. One CD-ROM holds about 600 megabytes, equal to more than 400 floppy
disks. Unlike a floppy disk, you cannot erase or edit the data on a CD-ROM.
disc -- re-writeable)
A blank compact disc that can be recorded more than once.
Cellular telephone service

CGI provides a standard way to run gateway programs, or scripts, on a web
server. CGI programs can process data from web page forms, generate web

A web site where users send messages to one another in real time. Chat
rooms differ from bulletin board services, which do not function in real
time and may use nonlinear formats, called threads, to organize information.
Circuit - Switched A type of network in which a physical path is obtained
for and dedicated to a single connection between two end-points in the
network for the duration of the connection.
The number of electromagnetic pulses that a computer processor emits, measured
in millions of cycles per second (megahertz, or MHz). A computer’s CPU
clock speed determines how quickly the CPU can perform calculations; a
computer with a higher clock speed is faster than an identical machine
with a lower clock speed.
Any computer system compatible with the original IBM personal computer

communications ports - are computer connections that link a mouse, modem,
printer or other peripheral device to a system. Most personal computers
come with two external com ports (also known as serial ports), along with
a number of "virtual" com ports that the computer’s operating system creates
to handle internal peripherals.
A technique for reducing voice files, maintaining quality to a level satisfactory
to support the application. Major telecom carriers use compression in order
to increase the traffic over lines and cables. See also MP3 format.
Any call which includes the connection of three or more callers simultaneously.
For example, GlobalTel offers conference calling on all its services for
up to 16 lines at once. See: http://www.globaltel.org/conference.html
The length of time a caller is accessing the system, i.e., from the time
the system comes off-hook in response to a ring signal, until the line
is back on-hook at the end of the call.
The concept of having all network data and voice traffic run through a
single connection based on Internet Protocol (IP). Since early 2000, networking
and telecommunications equipment companies, including Lucent Technologies
and Cabletron Systems, have preached this concept of convergence.
