A technician is building a new desktop PC and needs to ensure it can connect to a wired Ethernet network. Which component provides the physical interface for an RJ-45 network cable?
Serial port
PCI
NIC
USB port
A Network Interface Card (NIC) is a hardware component that provides the physical connection for a computer to a network. For wired Ethernet, this interface is typically an RJ-45 port. While many motherboards have an integrated NIC, one can also be installed as an expansion card into a Peripheral Component Interconnect (PCI) or PCI Express (PCIe) slot. Therefore, PCI is the slot used for an internal card, not the network interface itself.
