What are the key components of a computer network, and how do they interact?

 Key components of a computer network include routers, switches, cables, and devices with network interface cards (NICs). Routers direct data between different networks, while switches connect multiple devices within a single network, forwarding data based on MAC addresses. Cables (such as Ethernet) physically connect devices, and NICs enable devices to interface with the network. These components work together to facilitate communication and resource sharing.
