A network is defined as a collection of connected computers and devices like PCs, laptops, and mobile phones. The main components that make up a network are the nodes like computers and devices, communications devices that connect the nodes like routers and switches, and transmission media like cables and WiFi that allow communication between the nodes. The document provides examples of drawing network diagrams for a home network and a hotel network to illustrate these components.
