A modem converts the digital signals(used by computer)into analog signals(in telephones) and vice versa.

it is an DAC (Digital to analogue converter
MOdulate/DEModulate. It converts digital computer signals into analog ones for transmission over analog telephone lines, and then converts the signal back into digital on the other end.

A "modem" is considered a transceiver. It receives data, and sends data. But it also converts signals in the sense that it can be seen as a DAC (digital to analog converter) and a ADC (analog to digital converter). Most dialup, DSL, and cable modems are examples of that - they plug into your computer and converts from-and-to your ISP the data you're receiving and sending. The signals you send from your computer are typically digital and the modem converts them into analog ones.
MODEM:A modem takes digital signal from computer and converts them to analog for the phone and reconverts them back
The difference between computer engineering and digital electronics is that digital electronics represents signals. Computer engineering integrates several fields of computer science and electrical engineering to make computer systems. Digital electronics is the field of computers and computer controlled devices including the ones with analog inputs and outputs.
