What is networking?

As pertaining to computing, the field of networking encompasses the technologies and practices around connecting separate computing devices in order to share the data and resources among them. Networking enables devices such as computers, servers, smartphones, and other devices to communicate with each other, exchange information, and access shared resources.

Ethernet is one of the prominent technologies used in networking, particularly for wired connections within a Local Area Network (LAN). Ethernet provides a standard set of rules and protocols for transmitting data packets over a physical medium, such as copper or fiber optic cables. It enables devices within the same LAN to communicate with each other, share files, and access network resources.

Apart from Ethernet-based LANs, networking also encompasses Wide Area Networks (WANs), which connect geographically dispersed locations or networks. WANs utilize various technologies, such as leased lines, satellite links, or Internet connections, to establish connectivity between different LANs or remote locations.

In addition to wired networking technologies, Wi-Fi (Wireless Fidelity) plays a crucial role in connecting devices without the need for physical cables. Wi-Fi uses radio waves to establish wireless connections between devices within a specific range, enabling them to access a network and share data.

Networking technologies also involve the use of protocols, such as the Internet Protocol (IP), Transmission Control Protocol (TCP), User Datagram Protocol (UDP), and others, to govern the routing and delivery of data packets across networks. These protocols ensure reliable and efficient data transmission over the network.
