Encapsulation and encapsulation. The class of. NET is encapsulated at one time, and certainly the scalability is not so good. However, components are easy to use. So I don't care much about it. This encapsulated TCP component is encapsulated by the socket component of Delphi. It simply provides three attributes and three events. There are only a few public functions. The convenience of this component is that when one end is connected or disconnected,

What is socket 　　A socket interface is an API of a TCP/IP network. A socket interface defines many functions or routines. programmers can use it to develop applications on a TCP/IP network. To learn TCP/IP network programming on the internet, you must understand the socket interface.The

Socket connectionsA socket is a communication machine. By virtue of such a mechanism. The development of the customer/server system can be done on a local machine. Can also boast the network.There is a difference between the creation and use of sockets and pipelines. Because the socket clearly separates the client from the server.Socket connections:First, the ser

For TCP/IP, UDP, socket programming These words you are not very strange, right? With the development of network technology, these words are filled with our ears. Then I would like to ask: 1. What is TCP/IP, UDP?Where is the 2.Socket?What's 3.Socket?4. Will you use them? What is TCP/IP, UDP? TCP/IP (Transmission Control protocol/internet Protocol), the Transmi

Through the TCP protocol transmission, obtains is a sequential error-free data stream. A connection must be established between the pair of two sockets of the sender and receiver to communicate on the basis of the TCP protocol, and when one socket (usually the server

Http://www.jianshu.com/p/5d82a685b5b6After a long analysis of the socket creation source, found a piece of paste, so this summary, my blog at the same time there is another detailed source analysis, the kernel version of 3.9, it is recommended that after reading this article if you are interested in another blog post. Never look at another article alone.One: Call chain:Two: Data structureTake a look at the meaning of each data structure:1)

The socket is one end of two-way communication between two programs running on the network, it can accept the request, also can send the request, can use it to write the data on the network more conveniently. In Java, there is a special socket class to handle the user's request and response. Using the method of the socket class, you can realize communication betw

PHP socket programming is more difficult to understand things, but, as long as we understand the relationship between several functions of the socket, and the role they play, then it should not be difficult to understand, in my opinion, socket programming, in fact, is to establish a Network service client and server , this is the same as the client and server sid

customers can also be timely service. Second, two types of transmission protocol: TCP;UDP TCP is the short name of Tranfer Control protocol and is a connection-oriented protocol that guarantees reliable transmission. With the TCP protocol transmission, a sequential error-free data stream is obtained. A connection must be established between the sender and the receiver's paired two sockets to communicate on the basis of the TCP protocol, and when a socket
