andmesidevõrk

Andmesidevõrk, often translated as data network or communication network, refers to a system that allows the transmission and reception of digital data between various devices. These networks are fundamental to modern computing and communication, enabling everything from internet browsing to mobile phone calls.

There are many types of andmesidevõrk, categorized by their geographical scope and the technologies they employ. Local Area Networks (LANs) typically connect devices within a limited area, such as a home or office. Wide Area Networks (WANs) span much larger distances, often connecting multiple LANs across cities, countries, or even continents. The internet itself is the largest example of a WAN.

Key components of an andmesidevõrk include end devices like computers and smartphones, intermediary devices such as routers and switches that direct data traffic, and the communication media that carry the signals, which can be wired (like Ethernet cables) or wireless (like Wi-Fi or cellular signals).

Protocols are sets of rules that govern how data is formatted, addressed, transmitted, routed, and received within the network. Common protocols include TCP/IP, which forms the foundation of the internet, and HTTP, used for accessing web pages. The design and management of andmesidevõrk are complex fields, crucial for ensuring efficient, reliable, and secure data exchange.
