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. Read More..

Information technology

Information technology seen from the word penyusunnya is technology and information. Ease of information technology is the result of human engineering in the process of delivering information from the sender to the recipient, so that information will be:

* With the rapid
* More extensive sebarannya, and
* Storage older.

For more easy to understand let's see the developments in the field of information technology. At the beginning of history, to exchange information through human language. So is the language of technology. Language allows a person to understand the information presented by others. But the language that was delivered from mouth to mouth only survive only briefly, only when the sender to convey information through the apology. After discussion, the information in the hands of the recipient will be overlooked and can not be stored longer. In addition, the voice also limited reach. To a certain distance, even to hear, the information presented through the language will sound terdegradasi even lost at all.

After the delivery of information technology developed through the images. With the image information can reach more remote. This image can be captured and delivered goods to other people. In addition, there is information that will survive for long. Some images of ancient relics that still exist until now, so now people can (try to) understand the information that you want to become writers.

Finding Arabic alphabet and numbers easier ways of delivering information more efficient ways of the past. The image is a combination of events made by letter, or by writing the number, such as MCMXLIII replaced by 1943. Technology makes it easier to write the information in the letter.

Then, the printing technology that allows transmission of information more quickly again. Electronic technology such as radio, TV, computer information lead to a more rapid spread in the area that is wider and longer saved.
