What two criteria are used to help select a network medium from various network media?
The two criteria commonly used to help select a network medium from various network media are:
1. Bandwidth: Bandwidth refers to the capacity of a network medium to transmit data. It is measured in bits per second (bps). Higher bandwidth allows for faster data transmission, while lower bandwidth can result in slower data transfer rates. When selecting a network medium, it is important to consider the required bandwidth based on the network’s specific needs. For example, networks that require high-speed data transfer, such as video streaming or large file sharing, would benefit from a network medium with a high bandwidth.
2. Distance: Distance refers to the maximum length of the network medium that can be used for effective data transmission. Different network media have varying distance limitations. For example, Ethernet cables typically have a maximum length of 100 meters, whereas fiber optic cables can span much longer distances without signal degradation. When selecting a network medium, it is crucial to consider the physical layout of the network, the distance between the devices, and any potential obstacles or interference that may affect the signal quality.
