Lokaalnetwerk

Lokaalnetwerk, often abbreviated as LAN, refers to a computer network that interconnects computers within a limited geographical area such as a home, school, or office building. This limited area is the defining characteristic of a LAN, distinguishing it from wider networks like MANs (Metropolitan Area Networks) or WANs (Wide Area Networks).

The primary purpose of a lokaalnetwerk is to facilitate resource sharing among connected devices. This can include sharing internet connections, printers, files, and other peripherals. Devices within a LAN can communicate with each other directly, typically at high speeds, enabling efficient data transfer and collaboration.

Lokaalnetwerken can be established using various technologies, with Ethernet and Wi-Fi being the most common. Ethernet utilizes physical cables to connect devices, offering a stable and fast connection. Wi-Fi, on the other hand, uses radio waves to create a wireless network, providing flexibility and mobility for connected devices.

The setup of a lokaalnetwerk usually involves networking hardware such as routers, switches, and network interface cards (NICs). Routers connect multiple networks together, often linking a LAN to the internet. Switches connect multiple devices within the same network segment, directing traffic efficiently. Network interface cards are essential components within each device that allow it to connect to the network.

Security is a crucial aspect of lokaalnetwerk management. Measures such as firewalls, strong passwords, and encryption are implemented to protect the network and its data from unauthorized access and cyber threats. Managing user permissions and access controls further enhances security.
