Computer networking involves connecting computers and devices to share resources and communicate effectively. It includes various technologies and protocols that enable data exchange over wired and wireless connections. Key components of networking are routers, switches, and firewalls, which manage traffic and ensure security. Networking can be categorized into local area networks (LANs), wide area networks (WANs), and the internet. Understanding concepts like the OSI model, IP addressing, and subnetting is essential for efficient network management. Proficiency in computer networking is crucial for IT professionals, supporting business operations, cloud services, and the growing Internet of Things (IoT).
