What is a computer network and its basic components?

A computer network refers to a system that allows multiple devices to communicate and share resources with each other. It enables the transfer of data, information, and communication between computers, servers, and other network devices. The basic components of a computer network include nodes, which are the individual devices connected to the network such as computers, laptops, servers, and even smartphones. These devices are interconnected by transmission media, which can be wired (such as Ethernet cables) or wireless (such as Wi-Fi). Network switches act as intermediaries that facilitate the flow of data between the connected devices. Routers help in managing the traffic within the network and enable communication between multiple networks, while firewalls protect the network from unauthorized access and potential threats.
