Which type of connector is typically used to connect a network interface card to the network using UTP cable?

The type of connector that is typically used to connect a network interface card to the network using UTP (Unshielded Twisted Pair) cable is the RJ-45 connector. RJ-45 is specifically designed for networking applications and it accommodates eight wires, which allows for higher data transmission rates and reliable connectivity. This connector is commonly used in Ethernet networks and provides the proper interface for standard networking devices, including computers, switches, and routers.

In contrast, DB-25 connectors are generally used for serial communication, RJ-11 connectors are used for telephone lines and typically support fewer wires (four or six), making them unsuitable for network data transmission, and BNC connectors are typically used in coaxial cable systems, such as older video and certain network implementations. Thus, the RJ-45 connector is the optimal choice for connecting devices in modern networking environments.
