Computer networking is the process of connecting two or more computers so they can share data, resources, and information. It plays an important role in modern communication, allowing people and devices to connect through the internet or local networks.
A computer network can be as small as two computers connected in a home or as large as thousands of devices connected across the world. The most common type of network is the Local Area Network (LAN), which is used in homes, schools, and offices. Another popular type is the Wide Area Network (WAN), which covers large geographical areas and includes the internet.
Networking works using different devices such as routers, switches, and modems. A router helps connect multiple devices to the internet, while a switch allows devices within the same network to communicate. A modem connects your network to your internet service provider.
Computer networks use different communication rules called protocols. The most important one is TCP/IP, which helps data travel safely from one device to another. Other protocols like HTTP and HTTPS are used for browsing websites securely.
One major benefit of computer networking is resource sharing. Users can share files, printers, and internet connections easily. Networking also improves communication through emails, video calls, and cloud services.
In today’s digital world, computer networking is essential for businesses, education, and everyday online activities. Understanding the basics of networking helps users stay connected, work efficiently, and use technology more effectively.
