arvutuvõrgu

Arvutivõrk, commonly referred to as a computer network, is a collection of interconnected computing devices that can exchange data and share resources. These devices can include computers, servers, network-attached storage devices, smartphones, and other hardware. The connections between these devices can be established through physical cables, such as Ethernet, or wireless technologies, like Wi-Fi.

The primary purpose of an arvutivõrk is to facilitate communication and collaboration among its users. This allows for the sharing of information, such as documents, images, and videos, as well as hardware resources like printers and internet connections. Networks can vary significantly in size and complexity, ranging from small home networks connecting a few devices to large enterprise networks spanning multiple buildings or even continents.

Arvutivõrgud are typically categorized into local area networks (LANs), which cover a small geographical area, and wide area networks (WANs), which span larger distances. The internet itself is the largest example of a WAN. Network protocols, such as TCP/IP, define the rules and standards for how data is transmitted and received across the network, ensuring reliable and efficient communication. Security is also a crucial aspect of arvutivõrk management, with measures like firewalls and encryption employed to protect data from unauthorized access.
