Connection to the Internet

PC Hardware Resistor – Connector Light emitting diode (LED) Random-access memory (RAM) Read-only memory (ROM) Expansion slot Power supply Network interface card (NIC)

NIC Protocols – Ethernet, Token Ring, or FDDI Types of media – Twisted-pair, coaxial, wireless, or fiber-optic Type of system bus – PCI or ISA A NIC must be installed for each device on a network Situations that require NIC installation include the following: Installation of a NIC on a PC that does not already have one Replacement of a malfunctioning or damaged NIC Upgrade from a 10-Mbps NIC to a 10/100/1000-Mbps NIC Change to a different type of NIC, such as wireless Installation of a secondary, or backup, NIC for network security reasons
