Tölvunetum

Tölvunetum is the Icelandic word for computer network. A computer network is a collection of interconnected computers and other devices that can communicate with each other and share resources. These networks can range in size from small local area networks (LANs) connecting a few computers in a home or office to large wide area networks (WANs) spanning vast geographical distances, such as the internet.

The primary purpose of a tölvunet is to facilitate the exchange of information and the sharing of hardware and software resources. This allows multiple users to access shared printers, files, and internet connections, increasing efficiency and reducing costs. Networks are built using various hardware components, including routers, switches, cables, and network interface cards (NICs), and operate using standardized communication protocols like TCP/IP.

Different types of tölvunetum exist, classified by their geographical scope and topology. LANs are typically found within a single building or campus. MANs cover a metropolitan area, while WANs connect networks over large regions or globally. The internet itself is the largest example of a WAN, a global network of interconnected computer networks. Understanding tölvunetum is fundamental to modern computing and communication.
