tcp/ip protocol internet

The proprietary feature of the internet is "using the TCP/IP protocol". TCP/IP is the core protocol of the Internet, used to ensure that data reaches the designated destination safely and reliably. The TCP/IP protocol mainly includes two main protocols, namely the TCP (Transmission Control) protocol and the IP protocol. These two protocols can be used in conjunction with each other or with other protocols.

What are the unique features of the internet?

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

The proprietary feature of the Internet is "the use of TCP/IP protocol".

The Internet, also known as the international network, refers to a huge network connected between networks. These networks are connected by a set of common protocols to form a single logical network. Huge international network.

The Internet adopts the most popular client/server working model. Any computer that uses the TCP/IP protocol and can communicate with any host on the Internet, regardless of type and operating system. , can be regarded as part of the Internet.

Internet Core Protocol

Computer network is composed of many computers. To realize the transmission of data between computers in the network, two things must be done. The purpose of data transmission Address and measures to ensure rapid and reliable transmission of data. This is because data is easily lost or mistransmitted during the transmission process. The Internet uses a specialized computer language (protocol) to ensure that data reaches the designated destination safely and reliably. This language is divided into two parts: TCP (Transmission Control Protocol) and IP (Internet Protocol).

Data transmission process of TCP/IP protocol: The communication method used by TCP/IP protocol is packet switching. The so-called packet switching simply means that data is divided into several segments during transmission. Each data segment is called a data packet. The basic transmission unit of the TCP/IP protocol is a data packet. The TCP/IP protocol mainly includes two main protocols, namely TCP protocol and IP protocol, these two protocols can be used in combination or in combination with other protocols. They mainly complete the following functions during the data transmission process:

  • (1) Firstly, The TCP protocol divides the data into several data packets and writes a sequence number on each data packet so that the receiving end can restore the data to its original format.

  • (2) The 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 data packet can transmit data on the physical network. . The IP protocol also has the function of utilizing routing algorithms for routing selection.

  • (3) These data packets can be transmitted through different transmission channels (routing). Due to different paths and other reasons, order reversal, data loss, and data distortion may occur. Even repeated phenomena. These problems are handled by the TCP protocol, which has the function of checking and handling errors, and can also request the sending end to resend when necessary. In short, the IP protocol is responsible for the transmission of data, while the TCP protocol is responsible for the reliable transmission of data.

Characteristics of the Internet:

1. Flexible and diverse ways of networking. This is because TCP/IP successfully solves the compatibility issues between different hardware platforms, network products, and operating systems.

2. It adopts the most popular client/server model in distributed networks, which greatly improves the flexibility of network information services.

3. The integration of network technology, multimedia technology and hypertext technology reflects the development trend of modern integration of various information technologies.

4. Convenient and easy. The Internet can be accessed from anywhere simply through a telephone line or an ordinary computer.

5. Provide users with extremely rich information resources, including a large number of free resources.

6. It has complete service functions and a friendly user interface, which is easy to operate and does not require users to master more professional computer knowledge.

Extended knowledge: TCP/IP

TCP/IP (Transmission Control Protocol/Internet Protocol, Transmission Control Protocol/Internet Protocol) refers to the ability to communicate on multiple different networks A protocol suite that implements information transmission between The TCP/IP protocol not only refers to the two protocols TCP and IP, but also refers to a protocol cluster composed of FTP, SMTP, TCP, UDP, IP and other protocols. Just because in the TCP/IP protocol, the TCP protocol and the IP protocol The most representative, so it is called TCP/IP protocol.

The TCP/IP protocol can develop rapidly and become a de facto standard because it just meets the needs of data communication around the world. It has the following characteristics:

(1) The protocol standard is completely open, can be used by users for free, and is independent of specific computer hardware and operating systems.

(2) It is independent of the network hardware system, can run on the wide area network, and is more suitable for the Internet.

(3) Network addresses are uniformly allocated, and each device and terminal in the network has a unique address.

(4) High-level protocol standardization can provide a variety of reliable network services.
