Network and Communication refer to the interconnected systems and devices that enable the transfer of data and information between various endpoints. The main components of a network and communication system include hardware devices such as computers, routers, switches, and modems, and software protocols that govern the flow of data between these devices. Networks can be classified into several types, including local area networks (LANs), wide area networks (WANs), metropolitan area networks (MANs), and wireless networks (Wi-Fi and cellular networks). Communication protocols, such as TCP/IP and HTTP, enable devices to communicate with each other by establishing a common language and set of rules for exchanging data.
