Networking functions refer to the various tasks and processes that enable devices to communicate over a network. These functions include data transmission, error detection, and routing, which help ensure that information is sent and received accurately. Networking functions are essential for both local area networks (LANs) and wide area networks (WANs), facilitating seamless connectivity between computers, servers, and other devices. Key components of networking functions include protocols, such as TCP/IP and HTTP, which define the rules for data exchange. Additionally, devices like routers and switches play crucial roles in directing traffic and managing data flow. Together, these functions create a reliable and efficient communication environment.
