Chapter IV: Infrastructure Of Online Trading Part-4:

TCP/IP:

Protocol, which provides solutions in the field of communication between global internetworks is
Transmission Control Protocol/Internet Protocol.
This means that any computer to the system or connected to the Internet, it uses TCP/IP

In fact, this protocol is a two protocols:

1-Transmision Control Protocol TCP.

2-Internet Protocol IP.

The transmission control protocol function is to make sure that the two robots can communicate with each other Reliable manner. Contact for transmission control protocol must be offset by the receipt of data poems. If not This is obtained after a certain period of notification, the sender of the re-transmission of data. In order to The process of transmission or a response to the request, the request sender should be split into sections called small Each package contains the device address of the sender and the future. Here interfere protocol packets. Packet The Internet. Internet Protocol packets and coordinates the distribution of addresses.

Using the current version Internet Protocol, the number of titles available for just over 4 billion (2 S 32). This figure seems very high especially as the number of computers currently in the world is in Millions only. The problem is that the distribution of news items are not individually, but collectively. For example, when the HP free to request an electronic address, the group was given the headlines "15." This means that HP Company Employing more than 16 million starting from the address 15.0.0.0. To 15.255.255.255. And smaller groups are given For smaller firms.

The only positive for the mass distribution of the addresses online is to reduce the burden of covering the fact that if the custom made Address that starts at 15, this means that the data must go to the computer to present the The problem, however, that the number of titles available will be greatly reduced in the coming years. This is why HP. Network Reason, many experts have begun the design of Next Generation Internet Protocol IPng.

This protocol - which was re-named to the Protocol Internet version of the sixth - has been used only recently and uses 128-bit for the formulation of Addresses. This allows the computer to billion (number one in his right hand and 15 is zero) to contact the Internet.
