Using Telecommunication Applications in P.E.

The definition of telecommunication is any type of data transfer between two points. A network consists of individually controlled computers that are in communication with one another. No cable is needed when there is a wireless network. Networks can connect two individuals in an office, or can link a group of offices in a school. Networks also allow computers to share hardware devices such as laser printers, color printers, and scanners, and to exchange messages between computers. If there is no wireless system or cable to a network, then some type of modem is needed. The three types of modems are dial-up, cable, and DSL along with the three sizes which are external, internal, and PC card. In order to use the modem, a telephone wire or cable wire needs to connect from the wall to the line port on the modem.
