Netzwerkmedium

Netzwerkmedium, also known as network medium, refers to the physical or logical channel through which data is transmitted in a computer network. It encompasses various types of media, each with its own characteristics and applications. The most common types of network media include:

1. Copper wire: This includes twisted pair cables, such as Ethernet cables, which are widely used in local area networks (LANs). Copper wire is relatively inexpensive and easy to install, but it has limitations in terms of distance and data transmission speed.

2. Fiber optic cable: Composed of glass or plastic fibers, fiber optic cables transmit data using light pulses. They offer high bandwidth, low signal loss, and immunity to electromagnetic interference, making them ideal for long-distance and high-speed data transmission. However, they are more expensive and require specialized equipment for installation and maintenance.

3. Wireless media: This category includes various wireless technologies, such as Wi-Fi, Bluetooth, and cellular networks. Wireless media allows for flexible and mobile connectivity, but it is subject to interference, signal degradation, and security concerns.

4. Coaxial cable: Although less common in modern networks, coaxial cables were historically used for cable television and early Ethernet networks. They consist of a central conductor surrounded by an insulating layer and a conductive shield.

The choice of network medium depends on factors such as the required data transmission speed, distance, cost, and environmental conditions. Additionally, the selection of network medium can impact the overall performance, reliability, and security of a computer network.
