Python network programming Python socket programming, python Network Programming
Python provides two levels of network services for access.
Low-level network services support basic Sockets. It provides the standard BSD Sockets API and can access all the methods of Socket interfaces of the underlying operating system.SocketServer, a high-level network service modu
network communication Mode
There are two kinds of existing network communication methods:
1.TCP (Transmission Control Protocol) mode
TCP is a connection-oriented reliability transport protocol, TCP is like a telephone, use this way to communicate, need to establish a dedicated virtual connection, and then reliable data transmission, if the data sent failed, the client will automatically resend the data.
2.UDP (User Datagram Protocol) mode
UDP is a connectionless protocol, each datagram is a sepa

JAVA notes: Java Network Programming (3) TCP programming, network programming tcp
In Java, Socket is used to develop TCP programs. Point-to-point communication connections can be established.
In Socket program development, the server uses ServerSocket to wait for the client connection. For Java Network programs, each client uses a Socket object.

Man invented the programming language in order to control the machine. Computers are becoming more powerful, and programming languages are constantly being innovated. So I boldly believe that the meaning of programming language will be beyond the control of the machine, it may be a starting point of civilization-robot civilization. To better envision the

Getting started is the hardest.

Introduction: The difference between procedural programming and object-oriented programming is not whether to use functions or classes. that is to say, procedural programming may be used for classes or objects, only functions are used, and object-oriented programming is also possible. So where are their differences? Pr
