This article is intended to describe some of the learning notesOSI layering: application layer, presentation layer, session layer, Transport layer, network layer, data link layer, physical layerDetail point:1. Application layer: provide services for the application and specify the details of communication in the program.2. Presentation layer: Converts the information processed by the application into a format suitable for network transmission, or conv

I would like to wait and read the books again. However, the company will have a seminar later. I will give you some comments! Open source is widely usedProgramPersonnel progress step by step, just a month to understand the realization of TCP/IP, more and more feel their own shortcomings. The grasp of the overall protocol, the division of tasks, the conversion between the kernel and the user, and the lock

TCP/IP network programming I/O Stream separation semi-closed (1) Theoretical Basis Stream: After fopen is called to open a file, file read/write operations will create a stream, and Socket network communication will also create a stream. A stream is a bridge for data sending and receiving purposes, it is actually the flow of exponential data. We can understand i

1. What is a Socket? (What is a socket)A socket is an abstraction through which an application could send and receive data, in muchThe same-a open-file handle allows an application-read and write data to stablestorage.Simply put, sockets are software devices for network data transmission.Give a life example:We plug the plug into the socket and get a power supply from the grid, in the same way that the remote computerData communication requires a conne

Lab environment setup:The operating system is Windows server, because there is only one computer in the dormitory, and there is no Nic, there is only one 56 K old cat), so the Virtual Machine VMware-workstation can be downloaded in many places on the Internet, download is not provided here, and installation is simple); The Virtual Operating System is RedHat 8.0. In order to save space and speed up, the graphic interface is not installed. You can search for the installation of the Virtual System

Now, in the network society, I don't know how to use TCP/IP for Linux. I feel empty. So you must study this stuff carefully. Tutorial objective: to implement client sending and server receiving ============= Server ============================== # Include ============= Client ============================= # Include The experiment results are as follows: Root @ WYZ-vlinux :~ /Test/SC #./tcp_serverSer
