arvutuvõrgustik

Arvutivõrgustik, often translated as computer network, is a system of interconnected computers and other devices that can communicate with each other and share resources. These networks can range in size from a small local area network (LAN) connecting a few devices in a home or office to a wide area network (WAN) spanning vast geographical distances, such as the internet.

The primary purpose of an arvutivõrgustik is to facilitate communication and data exchange between its connected nodes. This allows for the sharing of files, printers, internet access, and other resources, increasing efficiency and collaboration. Networks are built using various hardware components like routers, switches, cables, and network interface cards, along with software protocols that govern how data is transmitted and received.

Different types of arvutivõrgustik exist based on their scope and topology. LANs are typically confined to a limited area, while WANs connect multiple LANs over long distances. The internet is the largest example of a WAN. Network topologies describe the physical or logical arrangement of the network, with common examples including bus, star, ring, and mesh topologies, each offering different advantages in terms of performance, cost, and reliability. Security is a crucial aspect of any arvutivõrgustik, with measures in place to protect data from unauthorized access, corruption, or theft.
