This article mainly introduces "how to realize the communication between any two computers on the Internet by ip protocol". In daily operation, it is believed that many people have doubts about how to realize the communication between any two computers on the Internet by ip protocol. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the question of "how to realize the communication between any two computers on the Internet by ip protocol". Next, please follow the editor to study!

When sending or receiving a message, the gateway computer reads the destination address, and the packet continues to read the destination address as usual to the next neighboring gateway, until a gateway confirms that the packet belongs to the computer closest to it or within its range, and finally goes directly to the computer at its specified address.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

Each computer (host) on the network has at least one IP address that distinguishes it from other computers on the network. When sending or receiving information (for example, an e-mail message or a web page), the information is divided into small pieces called packets. Each packet contains the network addresses of the sender and receiver.

The gateway computer reads the destination address, and the packet continues to read the destination address as usual to the next neighboring gateway, and so on through the network until a gateway confirms that the packet belongs to the computer in its nearest neighbor or range. Eventually go directly to the computer at its specified address.

Extended data

The IP protocol is mainly used to interconnect heterogeneous networks, such as interconnecting LAN and WAN (using X.25 technology). Although the lower-layer network protocols used in these two types of networks are different, the LLC frames in LAN and X.25 packets in WAN can be exchanged with each other through IP in the gateway.

The frame format and address format of various networks are very different. TCP/IP unifies them through IP Datagram and IP address, and provides a unified IP Datagram to the upper layer (mainly the transport layer), so that the difference of physical frames in the lower layer no longer exists in the upper layer protocol, and achieves the purpose of shielding the lower layer and providing consistency.

Although IP protocol ensures that computers can send and receive datagrams, it is not responsible for solving the security problems such as the reliability of Datagram communication. These security factors are mainly completed by TCP protocol.

At this point, the study on "how to realize the communication between any two computers on the Internet by ip protocol" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
