If you ever connected a PC with a broadband connection you surely used an Ethernet cable to do it. Ethernet cables also called LAN cables or Cat 5 cables are often used in home networks. They are categorized into two types – Straight through and Crossover cables. Straight though cables are used to connect different types of devices (like PC to Hub) whereas Crossover cable is used to connect same type of devices such as PC to PC or Switch to Switch. Both the cables are almost identical except the wiring scheme of their end connectors. Depending on the type of the cable, straight through or crossover, both end connectors either have same or different types of wiring schemes, respectively. The connector consists of a mechanical lock which aids it to fix the cable in the port. Once a cable is thoroughly plugged into the device port a click sound is produced.
