CN 02: What is a Computer Network? Computer Networks Basics.
A computer network is a collection of interconnected devices that communicate and share resources, such as data, files, and applications. These devices, which include computers, servers, printers, and other hardware, are connected through various communication channels like wired (Ethernet cables) or wireless (Wi-Fi) links and other networking devices. Network Criteria A network must be able to meet a certain number of criteria. The most important of these are: 1. Performance. Performance in a computer network can be assessed through various metrics, including transit time and response time: Transit Time: This is the time it takes for a message to travel from one device to another. Response Time: This measures the elapsed time between a request and the corresponding response. Factors affect network performance, including: The number of users on the network The type of transmission medium (e.g., fiber optic, copper wire, wireless) The capabilities of the connected hardware (e.g., routers, switc…
