The correct answer is '8-pin Ethernet connector.' The RJ-45, an 8-pin Ethernet connector, is most commonly used for networking and is the standard for connecting workstations to a network switch. This allows the workstation to communicate with the network and access shared resources. The other options are not suitable as RJ-11 is typically used for telephone connections, not Ethernet networking; VGA and PS/2 connectors are used for video and older keyboard/mouse devices respectively, and are not used for network connections.
