HTTP (Hypertext Transport Protocol), which is the Hypertext Transfer Protocol. This protocol details the rules for communicating with each other between the browser and the World Wide Web server.Characteristics: HTTP is called Hypertext Transfer Protocol, based on request/Response mode! HTTP is a stateless protocol. In order to facilitate the understanding of HTTP request and response protocol, use a section of PY to grasp packet analysisimport socketimport timedef handl

DD Command Feature Copies the specified input file to the specified output file and can be formatted for conversion during the copy process. You can use this command to realize the function of the diskcopy command under DOS. First use the DD command to write the data on the floppy disk as a storage file, and then put the storage file into the second floppy disk, complete the function of diskcopy. It should be noted that the storage files on the hard disk should be removed with the RM command. T
