arvutivõrkudes

Arvutivõrkudes is the Estonian term for computer networks. A computer network is a set of computers sharing resources and information. These resources can include files, printers, and internet access. The most common type of computer network is the internet, which connects billions of devices worldwide.

Computer networks can be classified by their size and scope. A local area network (LAN) connects devices within a limited area, such as a home or office. A wide area network (WAN) covers a larger geographical area, such as a city or country. The internet is an example of a global network.

Networks facilitate communication and data sharing. Devices in a network are connected using various technologies, including Ethernet cables, Wi-Fi, and fiber optics. Data is transmitted between devices in packets, which are small units of information. Protocols, such as TCP/IP, govern how these packets are sent, received, and reassembled.

The primary purpose of computer networks is to enable efficient sharing of resources and information, enhance collaboration, and provide access to a vast range of services. They are fundamental to modern communication, commerce, education, and entertainment. Security is a critical aspect of arvutivõrkudes, with measures implemented to protect data and prevent unauthorized access.
