Network Interface Card (NIC)

It is a device that can be connected into a motherboard and provides ports for network media connections. It is a part of the computer that is connected to the Local Area Network (LAN). The network resources are automatically separated when they are installed which is not the case with older NICs. Some points to be considered while choosing NIC:

• The types of network – Separate NICs are needed for different network systems like Ethernet LANs, Fiber Distributed Data Interface (FDDI), Token Ring, etc. Hence, appropriate NIC should be chosen.
• The type of media – port or connector available in NIC is media specific for e.g. twisted-pair cable, coaxial cable, optical fiber cable, and wireless.
• The type of system bus – PCI (Protocol Control Information) slots perform faster than ISA (Industry-Standard Architecture).
