Modem, NIC, Telephone connection, cable.
Modem: Modem is called modulator/demodulator. It converts digital signal into analog for transmission and vice versa.
NIC (Network Interface Card): It is the means by which the workstations are connected functionally and physically to the network. It is microprocessor bases device. Comes with software/driver which is to be installed. Software supplies the intelligence to control access to and communications across the network and to perform all communication processing.
