#computerads #computerworld
This is a modem. It function like today modem. Your PC - model - line to outer world.
The line to outerworld nowaday is fiber optic cable. Long ago, we use phone line. A bit more years back then, we put the whole "handset" to the modem so our modem can "talk" to server using machine language, in voice (boop beep boop beep)
