(International) Internet; internet
Internet belongs to the field of media. The Internet, also known as the Internet, began in 1969 in the United States. It is a huge network connected in series between networks, which are connected by a set of common protocols to logically form a single huge international network.
The Internet is different from the World Wide Web. The World Wide Web is just a global system based on hypertext links, and it is one of the services that the Internet can provide.
Extended data:
In the process of data transmission, they mainly complete the following functions:
1. First, the data is divided into several data packets by TCP protocol, and the serial number is written for each data packet, so that the receiver can restore the data to the original format.
2.IP protocol writes the addresses of the sending host and the receiving host for each data packet. Once the source address and destination address are written, the packet can transmit data on the physical network. IP protocol also has the function of routing with routing algorithm.
3. These data packets can be transmitted through different transmission paths (routes). Due to different paths and other reasons, the order may be reversed, data may be lost, data may be distorted or even repeated.
These problems are handled by TCP protocol, which has the function of checking and handling errors, and can also request the sender to resend when necessary. In short, IP protocol is responsible for data transmission, while TCP protocol is responsible for reliable data transmission.
