Arvutivõrkud

Arvutivõrkud refers to computer networks in Estonian. A computer network is a group of two or more interconnected computing devices that can share resources and exchange data. These connections can be made using physical cables, such as Ethernet, or wirelessly, like Wi-Fi. Networks vary in size and complexity, from small home networks connecting a few devices to large enterprise networks spanning multiple buildings or even continents.

The primary purpose of computer networks is to enable communication and resource sharing. This allows users to access shared files, printers, and internet connections. Networks also facilitate collaboration by enabling users to work together on projects simultaneously, regardless of their physical location. Security is a crucial aspect of network design, with various measures implemented to protect data from unauthorized access and cyber threats.

Common types of computer networks include Local Area Networks (LANs), which cover a small geographical area like a home or office, and Wide Area Networks (WANs), which connect devices over a large geographical area, such as cities or countries. The internet is the largest example of a WAN, connecting billions of devices worldwide. Network protocols, such as TCP/IP, govern how data is transmitted and received across networks, ensuring reliable communication. Understanding arvutivõrgud is essential in today's digitally interconnected world.
