The primary function of a computer network is to facilitate the communication and sharing of resources among interconnected devices. By allowing computers and peripherals to send and receive data, networks enhance collaboration and usability within organizations. This connectivity enables users to access shared files, applications, and internet resources efficiently. Additionally, computer networks support various communication protocols and services, such as email, video conferencing, and data transfers. Overall, the ability to link devices creates a more efficient work environment, fosters innovation, and ultimately leads to enhanced productivity.
