Cat6 has a higher bandwidth compared to Cat5. The big difference between Cat5 and Cat6 cables is the amount of data that can be sent. For this reason, and the relatively high purchase costs of fiber optics, a Cat5 or Cat6 cable is often used in homes. While a copper Cat5 cable can achieve a bandwidth of 1000 Mbit / s. For example, if you have connected a media server to your television and want to stream an 8K resolution film on it, then the required bandwidth is 'only' 100 Mbit / s. The use of fiberglass in a home is actually superfluous. Impediments in this system, however, lay in the equipment that has to send the data: the routers and switches. Many and very fast data can be communicated internally. The advantage of optical fiber is the lack of theoretical limit in the bandwidth and speed of the data stream. The system used for this is called optical telecommunication, better known as fiber. With large internet providers and hosting companies, this exchange of data is done by means of light.
A network consists of different systems which are linked together and can exchange data with each other.
