lokaalvõrgud

Lokaalvõrgud, also known as Local Area Networks (LANs), are a fundamental component of modern computing infrastructure. A LAN is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building. This limited geographical scope distinguishes a LAN from a wider network, such as a Wide Area Network (WAN), metropolitan area network (MAN), or global network like the Internet. The primary purpose of a LAN is to facilitate resource sharing among its connected devices. This can include sharing files, printers, and internet access.

LANs are typically characterized by high data transfer rates, allowing for quick and efficient communication between devices. The technology most commonly associated with LANs is Ethernet, which defines the physical cabling and signaling standards. Wireless Local Area Networks (WLANs), often referred to as Wi-Fi, have become increasingly prevalent, offering greater flexibility and mobility without the need for physical cables. In a typical LAN setup, devices are connected to a central switch or hub, which then directs traffic between them. Security is also a key consideration for LANs, with various protocols and configurations implemented to protect data and prevent unauthorized access. The management and maintenance of a LAN are crucial for ensuring its performance and reliability.
