Computer networking is the practice of interconnecting multiple computers and devices to facilitate communication and data exchange. This allows users to easily share information and resources. Here’s a brief overview: Basics of Computer Networking: Nodes: These are the devices connected to a network, such as computers, routers, and switches. Links: The connections between nodes, which can be wired like cables or wireless. Protocols: Rules and standards that govern data transmission, like TCP/IP and HTTP.
