Network Cables and Connectors - SS3 ICT Lesson Note

Network cables and connectors are essential for connecting devices in a computer network. Ethernet cables are common for wired connections. They use RJ-45 connectors to plug into network jacks on devices like computers, routers, and switches. These cables transmit data as electrical signals. Fiber optic cables use light signals and connectors like SC or LC to transmit data at high speeds over longer distances. In wireless networks, devices connect via Wi-Fi using radio waves and don't require physical cables. These cables and connectors are the physical backbone of networks, enabling data transfer between devices.
