That framework was made by a great deal of PCs associated together, similar to a web.
That web was separated in LAN – Local Area Networks.
Those PCs could speak with each other even is some of them were out of administration. From that time the Internet is at this point around the world, or WWW – World Wide Web
The convention that principles every one of these PCs is TCP/IP:
TCP = Transmission Control Protocol
IP = Internet Protocol
The great normal for this convention is the way it manages the data sent and got. The ordinary telephone transmission works thusly:
From point A specifically to point B, utilizing link or radio association. So if something incorrectly happens to the radio transmitter or to the link, the correspondence is outlandish.
With the TCP/IP convention, despite what might be expected, the association from A to B is not immediate.
The data (record) that we need to send is separated in a few sections, bundles, and every parcel has a touch of the entire data.
Every parcel has a header and a footer, where are store all the sign for conveyance what is being sent (Address, sender, number of the bundle).
These bundles take after various ways of the net, going through various PCs, so regardless of the possibility that some of them are not working, the record utilizes the ones which are working appropriately. The PCs might be everywhere throughout the world. After this trek the document is reconstructed in the correct way.
For example, on the off chance that we send a record to a PC that is in a house near our office, might be that before touching base to goal, it goes to Europe and back.
To endeavor to see a tad this framework, we can do this extremely basic illustration:
We need to send a letter to somebody. Rather than sending only one sheet of paper, we could send 6 sheets. Every one contains 1/6 of the entire letter.
On the 6 envelopes we compose the sender, the address of the getting individual and the quantity of the (Letter n. 1, letter n.2, et cetera).
At that point we can send this letters, from a few Post Office or from only one.
The individual who gets every one of these letters, needs to takes after the number on each letters (1,2, 3…) to have the capacity to peruse the entire message.
This is great additionally for security: on the off chance that somebody gets a few letters, he has just piece of the message not the entire message.
