An Ethernet cable connector, also known as an RJ45 connector, is a type of electrical connector used to connect Ethernet cables to devices such as computers, routers, and switches.
Ethernet cable connectors are made of plastic and have eight pins arranged in two rows. The pins are used to transmit data between the devices that are connected by the cable. Ethernet cable connectors are typically used in local area networks (LANs) to connect computers and other devices to each other.
