You probably know what a modem is, but do you know how they

work? What they do? And why they are used? This report will explain

what they do and why we use the modem today.

A modem stands for modulator-demodulator, it is a device or

program that allows your computer to transmit data and information over

telephone lines. A modem converts digitally stored data in a

computer to analog waves in order for the information to be passed

through the telephone lines.

The different types of modems can be determined by their

characteristics. Wideband modems are used in large-volume

telephone-line multiplexing, dedicated computer-to-computer links.

These modems produce high data rates. Wideband belong to the "Range"

Category. Modems can be classified by these characteristics.

A protocol is for communication between computers, used as a

standard for transmitting data over networks and as the basis for standard

Internet protocols. Modems use these protocols, an example of a protocol

is TCP/IP ( Transmission Control Protocol / Internet Protocol )

Modems have lots of features. The more we advance into the future,

the more better our modems and communication become. Some will have

more faster connection speeds, and better connection rates. As we

advance, the modems and services will become cheaper in price.

Modems are now used everywhere. Including homes and businesses,

and in the future the modem will be used anywhere you can think of.

Since science is advancing everyday, we can expect other ways of

telecommunicating or we can expect better modems in the future.
