Networking refers to the practice of connecting computers, devices, and systems to facilitate data exchange, resource sharing, and communication. It encompasses both wired and wireless technologies to create local area networks (LANs), wide area networks (WANs), and industrial LANs. Networking includes essential components like routers, switches, firewalls, and gateways that manage data flow and maintain network security. Additionally, it involves networking accessories like software, cables, and converters that enhance connectivity and streamline management. Networking is crucial for enabling seamless communication, optimizing data traffic, and ensuring reliable internet and intranet connectivity for homes, businesses, and large enterprises.
