ITvõrgu

IT võrk, or IT network, refers to a collection of interconnected computers and other hardware devices that can communicate with each other. These networks are essential for modern businesses and individuals, enabling the sharing of resources, data, and applications. The fundamental purpose of an IT võrk is to facilitate communication and data transfer between its components.

IT võrgud can vary greatly in size and complexity. Local Area Networks (LANs) typically connect devices within a limited geographical area, such as an office building or a home. Wide Area Networks (WANs) span larger geographical regions, connecting multiple LANs across cities, countries, or even continents, with the internet being the most prominent example of a WAN.

The components of an IT võrk include hardware like computers, servers, routers, switches, and cables, as well as software that manages the network's operations and ensures secure data transmission. Network protocols, such as TCP/IP, define the rules for how data is sent and received across the network. The design and management of IT võrgud are critical for ensuring reliable performance, security, and scalability. Proper network infrastructure allows for efficient collaboration, access to information, and the operation of various digital services that are integral to daily life and business operations.
