why do we use modems?

Answer 1

To make your PC communicate with the phone line

Answer 2

When we want to use Telephone line to connect with Internet through service provider , then the modem on the PC works as the communication device. These built-in modems are called dial-up modems, bcuz they can dial out the ISP number and get connected with modem at ISP end.

Similarly , we can have DSL modem , if we have DSL service available through telephone line. Therefore, word modem refers to communication device which can modulate and demodulate the signals.

Answer 3

We use MODEMs (from modulate and demodulate) as a connection device to the Internet or to connect networks. There is a ton of different types of MODEMs which include your dial-up types or the high speed types of ADSL, DSL or Cable types.

MODEMs are not necessarily directly connected to your computer but the vast majority are.

http://en.wikipedia.org/wiki/MODEM is a very good page in the details of what a MODEM is, the history and their use.

Answer 4

Modem stands for MOdulator DEModulator. It is used to convert an analogue signal (i.e. the type that travels over a traditional phone line) into a digital signal that your PC can understand, and vice versa.

Answer 5

MOdulator DEModulator refer to devices for low-speedial-up or high speed broadband. Pertains only to dial-up modems which convert digital pulses from the computer to audio tones to an analog telephone line that is set up to handle and vice versa.
Until late 1990s term stood for devices that allowed a computer terminal to transmit data over the dial-up telephone line. Since the advent of high speed cable and DSL connnections, it may refer to devices for low-speeddial-up or high speed broadband. For high speed broadband you may find cable modems, DSL and cellular modems.

Answer 6

It's a device that converts the digital signal from a computer to an analogue signal that can be transmitted along an ordinary phone line. This allows computers to connect to the Internet through a telephone line.

Answer 7

A modem converts digital signals to analogue and back again. The allow digital signals to be transferred over analogue lines.

Answer 8

Modems allow you to communicate with the Internet. They allow you to send requests out onto the Internet and get answers back from the internet in the forms of web pages and other things.

Answer 9

They modulate and demodulate the data so they can squeeze it through a narrow pipline.

Answer 10

you just plug them into your computer and away you go!! normally you should get a cd with it to install it!
