Lokaalvõrk

Lokaalvõrk, also known as a local area network (LAN), is a network that connects computers and devices within a limited geographical area, such as a home, office, or group of buildings. LANs are typically used to share resources, such as printers, files, and internet connections, among connected devices. They can be wired or wireless, with wired LANs using Ethernet cables for connections and wireless LANs using Wi-Fi technology.

LANs operate at the data link layer and physical layer of the OSI model, and they use protocols such as Ethernet and Wi-Fi to transmit data between devices. They can be further categorized into different types, such as peer-to-peer LANs, where devices communicate directly with each other, and client-server LANs, where a central server manages resources and communication.

LANs are an essential component of modern computing infrastructure, enabling users to access shared resources, collaborate on projects, and communicate more efficiently. They can be connected to wider area networks, such as the internet, through routers or gateways, allowing users to access online resources and services.

LANs can be managed and configured using various tools and software, such as network management systems, configuration management tools, and network monitoring software. They can also be secured using firewalls, encryption, and other security measures to protect against unauthorized access and data breaches.

In summary, a lokaalvõrk is a network that connects computers and devices within a limited geographical area, enabling users to share resources, collaborate, and communicate more efficiently. LANs can be wired or wireless, and they can be managed and secured using various tools and software.
