Principles of Network Computer Systems Work
Electrical signal and the signal in the form of electromagnetic waves on a computer network propagates / jet with the principles of the computer network. So that a network can exchange data and information, needed a tool called Modem (Modulator Demodulator), which works to change the analog signal into digital signal and vice versa.

There are 4 main components that are on a network, the sender (the sender information data), protocol (to which encodes and decodes data downloading information), media transmission (medium data transfer), and Receiver (the recipient of the information data).

Working principles, first set to send the signal information to the Receiver through the protocol, which encodes the digital signal into analogue signals and transmitting signals through the media and through the second protocol decodes digital signals back into prior to the Receiver.

Above principles can work in analogikan when the Japanese and British people are chatting via the Internet. When the Japanese typing a message in Japanese, the message is changed by the first protocol to the English so that English people can receive messages in English and vice versa when the British reply to the message, the message jerking the English language will be changed by the protocol first, before a Japanese to Japanese people. So in this protocol can be as translators term data and information.
