Network Communication refers to the exchange of data between devices over a network. This can occur through various mediums, such as wired connections like Ethernet or wireless methods like Wi-Fi. The primary goal is to enable devices to share information, resources, and services efficiently. In network communication, data is transmitted in packets, which are small units of information. These packets travel through routers and switches, which direct them to their destination. Protocols, such as TCP/IP, govern how data is sent and received, ensuring reliable communication between devices, whether they are computers, smartphones, or servers.
