Computer networking is the process of connecting two or more computers together so that they can communicate with each other. This allows users to share files, printers, and other resources, as well as access the internet. There are many different types of computer networks, including local area networks (LANs), wide area networks (WANs), and metropolitan area networks (MANs). LANs are small networks that typically connect computers in a single building or office. WANs are larger networks that connect computers over long distances, such as across cities or countries. MANs are a type of WAN that connects computers in a metropolitan area. Computer networks use a variety of protocols to communicate with each other. Protocols are sets of rules that define how data is sent and received over a network. The most common protocol used on the internet is TCP/IP. Computer networking is a complex subject, but it is essential for modern communication and collaboration. By understanding the basics of computer networking, you can take advantage of the many benefits that these networks offer.

Networking
A system of interconnected computers
and peripheral devices that can
exchange data and share resources with
each other.

2. What is computer networking?
A network is a collection of two or more
computers that are connected.
The computers on a network can communicate
with each other and share resources, such as
printers, files, and applications.
