What is Computer Networking?
Computer Networking is the practice of connecting computing devices to share resources, communicate, and exchange data. It forms the backbone of modern communication, enabling everything from internet browsing to enterprise data centers.
Internet Communication relies on networking protocols such as TCP/IP to ensure data is transmitted reliably across the globe.
Data Transmission involves sending and receiving data packets across networks, with proper addressing and routing.
Enterprise Networks connect employees, systems, and services within organizations, supporting business operations and collaboration.
Network Infrastructure includes routers, switches, firewalls, and cabling that form the physical and logical structure of networks.
