Use the right pipes in your network’s plumbing
September 24th, 2008Wiring in a network is like plumbing in a house. Just as pipes form the pathways through which water flows to and from your plumbing fixtures, a network’s wiring provides the pathways through which computers transmit data using electrical signals. The amount of data that computers can move through a wiring system at any one time depends on the characteristics of the wires, or pipes, installed. The larger the pipes, the more data the computers can send simultaneously.
You can think of a network’s bandwidth as the size of a network’s pipes. Bandwidth represents a range of usable frequencies and is measured in hertz (Hz). A higher hertz rating for a network medium means higher available bandwidth. Higher bandwidth translates into bigger pipes to carry data. Just because you have big pipes, however, doesn’t mean you always get to fill them completely. Therefore, it makes sense to try to measure the actual amount of data (called throughput) flowing through the pipes. Read the rest of this entry »
