helyhálózat

A helyhálózat, commonly referred to as a Local Area Network (LAN), is a computer network that interconnects computers and other devices within a limited geographical area. This area is typically a single room, office building, or a small group of buildings. Unlike Wide Area Networks (WANs) which span large distances, LANs are characterized by their shorter range and higher data transfer rates.

The primary purpose of a helyhálózat is to facilitate resource sharing among connected devices. This can include sharing hardware like printers and scanners, as well as software and data. Users on a LAN can easily exchange files, send messages, and access shared resources without needing to connect to the internet.

Common technologies used in the construction of a helyhálózat include Ethernet and Wi-Fi. Ethernet utilizes physical cables to connect devices, offering high speed and reliability. Wi-Fi, on the other hand, allows for wireless connections, providing greater flexibility and mobility.

The administration and management of a helyhálózat are typically handled by an IT department or a network administrator within the organization. Security is also a crucial aspect, with measures such as firewalls and access controls implemented to protect the network from unauthorized access and cyber threats. Helyhálózatok are fundamental to modern computing and business operations, enabling efficient communication and collaboration.
