A computer network connects computers and devices together to allow for sharing of information. Computers can connect either through wired or wireless connections. A network application allows programs running on different computers to communicate with each other using protocols like HTTP for web browsers and servers or SMTP for email. This facilitates information sharing and communication between interconnected devices on the network.
