Lähiasennusjärjestelmät

Lähiasennusjärjestelmät, or local area networks (LANs), are computer networks that cover a small geographical area, such as a single building, office, or group of buildings. These networks are designed to facilitate communication and resource sharing among connected devices within the same locality. LANs typically use high-speed connections, such as Ethernet cables or Wi-Fi, to ensure fast data transfer rates and low latency.

The primary components of a LAN include network interface cards (NICs) installed in each device, a network switch or hub to manage data traffic, and a router to connect the LAN to other networks, such as the internet or wide area networks (WANs). LANs can be further categorized based on their size and complexity, ranging from small home networks to large corporate networks.

One of the key advantages of LANs is their ability to enable seamless file sharing, printer access, and application sharing among connected devices. This makes LANs ideal for collaborative environments where multiple users need to access the same resources simultaneously. Additionally, LANs can enhance network security by isolating sensitive data and applications from external threats.

However, LANs also have limitations, such as limited geographical coverage and potential vulnerabilities to internal threats. To address these challenges, organizations often implement additional security measures, such as firewalls and intrusion detection systems, to protect their LANs from unauthorized access and cyberattacks.
