Network cables are physical cables used to transmit data between devices in a computer network. They carry digital signals from one device to another, allowing for communication and data transfer. Network cables are a fundamental component of wired networks and are available in different types, each suited for specific network requirements. Ethernet Cable (Category 5e, 6, 6a, 7): Ethernet cables are widely used for local area networks (LANs) and internet connections. They use twisted pairs of copper wires to transmit data signals. The category of the cable determines its performance, with higher categories offering faster speeds, higher bandwidth, and better interference resistance. Fiber Optic Cable: Fiber optic cables use thin strands of glass or plastic (optical fibers) to transmit data as pulses of light. Coaxial Cable: Coaxial cables consist of a central conductor surrounded by insulation, a metallic shield, and an outer protective jacket.
