Modems modulate (convert) a computer"s digital data to analog, transmit it, then demodulate (reconvert) it back to digital data for the receiving computer. Network system of interconnected computers, telephones, and/or other communications devices that can communicate with one another and share applications and data. Share peripheral devices such as printers, scanners, disk drives. Security of information, because of improved backup systems.
