Principles of Network Computer Systems Work

Electrical signal and the signal in the form of electromagnetic waves on a computer network worm / jet with the principles of computer networks. So the network can exchange data and information, needed a tool called a modem (modulator Demodulator), which is working to change the analog signal into digital signal and vice versa.

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

Principles work, the 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 Recipient.

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