Lähivõrkudest

Lähivõrkudest, also known as local area networks (LANs), are computer networks that connect computers and devices within a limited geographical area, such as a home, office building, or school campus. These networks allow devices to share resources like printers, files, and internet connections. Ethernet and Wi-Fi are the most common technologies used to establish LANs. Ethernet uses cables to connect devices, offering high speed and reliability, while Wi-Fi utilizes radio waves for wireless connections, providing flexibility and mobility.

LANs can be structured in various topologies, including bus, star, and ring, each with its own advantages and disadvantages in terms of performance, cost, and ease of management. The primary function of a LAN is to facilitate communication and data exchange among connected devices. This enables efficient collaboration, centralized data storage, and streamlined access to shared resources. For businesses, LANs are crucial for internal operations, customer service, and the secure transfer of sensitive information. In a home setting, a LAN allows multiple devices to share an internet connection and communicate with each other.

The security of a LAN is a significant concern. Measures such as firewalls, strong passwords, and network segmentation are implemented to protect against unauthorized access and cyber threats. The development of LAN technology continues to focus on increasing speed, improving security, and expanding wireless capabilities to meet the growing demands of modern digital environments.
