Fastnetværk

Fastnetværk, often referred to as wired networks, are communication systems where devices are connected using physical cables. The most common type of cable used is Ethernet, which transmits data signals as electrical impulses. These networks offer a stable and reliable connection, generally providing higher speeds and lower latency compared to wireless alternatives. They are widely implemented in homes, offices, and data centers for their consistent performance.

The fundamental components of a fastnetværk include network interface cards (NICs) in each device, cables to connect them, and often a central device like a switch or router. Switches intelligently direct data traffic between connected devices, preventing collisions and optimizing network efficiency. Routers, on the other hand, connect different networks together and manage internet access.

Security is another advantage of fastnetværk, as physical access to the cables is required to intercept data, making them inherently more secure than many wireless setups. While the setup requires physical installation and can be less flexible in terms of device placement, the benefits of speed, reliability, and security make fastnetværk a cornerstone of modern digital infrastructure.
