Computer Networking Devices Explained with Function
This tutorial explains the functions of the most common and the essential networking devices (such as Hub, Switch, Router, Bridge, Modem, NIC, Proxy and Gateway) in detail with examples.
Network Interface Card (NIC)
In the list of the networking devices, NIC stands on the first place. Without this device, networking cannot be done. This is also known as network adapter card, Ethernet Card and LAN card. NIC allows a networking device to communicate with the other networking device.
NIC converts the data packets between two different data transmission technologies. A PC uses parallel data transmission technology to transmit the data between its internal parts while the media that provides connectivity between different PCs uses serial data transmission technology.
