Bandwidth

The speed of the transfer of data is often related to the type of cabling and switches or hubs that are used in the network. Switches generally allow faster transfer of data than hubs due to the way they distribute the data. Some types of cabling, such as optical fibre transmit data at a faster rate than other types of cabling. The choice of cabling is dictated by the expected traffic load of the network and of course, cost. The faster types of cabling are often the most expensive.

The type of Internet connection in use affects the speed of data from the Internet. For home use, a broadband connection, for example, is able to send and receive data faster than a dial-up modem. For organisations, ADSL and ISDN lines are faster and can transmit data at different rates and, of course, at different costs.
