Lähiverkkoympäristö

Lähiverkkoympäristö, often referred to as LAN (Local Area Network) in English, describes a computer network that interconnects devices within a limited geographical area. This area is typically a home, office building, school, or a group of closely located buildings. The primary purpose of a lähiverkkoympäristö is to enable communication and resource sharing among the connected devices.

Devices within a lähiverkkoympäristö can include computers, printers, servers, smartphones, and other network-enabled gadgets. These devices are connected using various networking technologies, most commonly Ethernet cables or Wi-Fi. Ethernet provides a wired connection, generally offering higher speeds and reliability, while Wi-Fi offers wireless connectivity, providing flexibility and mobility.

Common functionalities within a lähiverkkoympäristö include sharing files and folders, accessing a common internet connection, printing to shared printers, and playing multiplayer games. The size and complexity of a lähiverkkoympäristö can vary greatly, from a simple home network with a few devices to a large corporate network spanning multiple floors.

Security is an important consideration in lähiverkkoympäristö. Measures such as firewalls, passwords, and encryption are often implemented to protect the network and its data from unauthorized access and malicious threats. Network administration involves managing these devices, ensuring smooth operation, and troubleshooting any issues that may arise. The concept of lähiverkkoympäristö is fundamental to modern digital connectivity.
