Thread: Modem transmit data over the network

Modem is a device that is used to transmit data over the network. Your computer sends data in binary code to your modem which converts the binary-coded data to an analogue signal. This data then travels along the telephone network. When the data reaches the destination computer, the modem connected to that computer converts the analogue signal back into binary-coded data which can be read by the computer. Thus the modem transmits data over the network.



There are two types of modem: External modem and Internal modem. The External modem has to be connected to your computer and your telephone line with cables and electric socket while the Internal modem is built inside your computer. The billing meter of your telephone starts moving the moment you get connected to the Internet. So a modem with good speed ensures low telephone bills. Modem with a speed of 28,800 bps is recommended, but you can also use the one having a speed of 14,000 bps.
