Simply Know About FTP Server(II)

There are different FTP applications based on different operating systems, and all of them follow the same protocol, so that the users can transfer their files to others or obtain files from other users’ environments.square steel tubing prices

Like most Internet services, FTP is also a client/server system. The user connects to the FTP server program on the remote host through a client program supporting FTP protocol. The users send commands to the server program through the client program. The server program executes the commands issued by the user and returns the results to the client. For example, a user sends a command that requests the server to send a copy of a file to the user. The server responds to this command and sends the specified file to the user’s machine.

Software Application

In the use of FTP, the users often encounter two concepts: “Download” and “Upload”. “Download” file is to copy files from the remote host to their own computer; the “upload” file is to copy files from their own computer to the remote host.

When using FTP, you must login first, and upload or download files only after you get the corresponding permissions on the remote host. That is to say, if you want to transfer files with which computer, you must have the appropriate authorization of which computer.

This situation violates the openness of the Internet. There are more than ten million FTP hosts on the Internet. It is impossible to require every user to have an account number (or ID) on every host. Anonymous FTP is designed to solve this problem.

The Development History of the Market Economy System (V)

The third phase

The third stage is the “national regulation market, market-oriented enterprises” from 1987 to 1992.

In October 1987, the 13th National Congress of the Communist Party of China published a new theoretical summary of the socialist market mechanism on the basis of the planned commodity economy theory, stating: “The system of socialist planned commodity economy should be planned and the unified market-inherent system. The model of “national regulation of the market and market-oriented enterprises” proposed by the 13th National Congress of the Communist Party of China is a major development of the theory of planned commodity economy. In this stage, the “market” has been occupied in the national economy. A considerable proportion has even begun to play a leading role in some areas.metal coil suppliers

The Fourth stage

The fourth stage was the establishment and construction of a “socialist market economic system” from 1992 to 2003.

In September 1988, in response to problems arising from economic overheating and inflation, the Third Plenary Session of the 13th CPC Central Committee decided to rectify and rectify in accordance with the principle of “governing the economic environment, rectifying the economic order, and comprehensively deepening reforms.” During this period, the reform has stagnated. The government has strengthened its administrative control over the economy, and its role in direct planning adjustment has been prominent.
