MODEM is a input device device which is used to MODULATE & DEMODULATE the given signals into the corresponding opposite signals.

since this modem will be conected to PC or LAP and other end of it will be connected to the wires from outside. so this modem converts DIGITAL to ANALOG signals and vice versa. correspondingly. this much only wat i know


thank u

Basically we use digital signals in computer. But we use analog type of communication through wires .So our digital signal needs to be converted into analog signals. This is achieved through the usage of modem . Modem stands for MOdulator DEModulator . Its acts as a modulator thereby converting our digital signals into analog signals.These analog signals can be sent through phone line. In the receiving end the analog signals are again converted into digital signals.

Digital signals have two states { logic 0 and logic 1 }

comment am i wrong or rite .. :D ....
