1. Make preparations beforehandBefore communicating with others, you must prepare in advance, imagine the other party's possible response, and design different solutions based on different responses.Case: when talking to the boss about salary, the boss may have the following reaction: The boss can't say anything about the evil spirits, the hard-hearted saying that the company's finances are not allowed, and the boss will discuss it later, you must have a mature solution to improve the success ra

Inter-process communication is actually between different processes to spread or exchange information between the different processes require some mutual access to the media, the process of user space is independent of each other, generally can not access each other, the only exception is the shared memory area, on time system space of public places, So the kernel can obviously provide a condition that, for the first time, is a peripheral that can be

;Second handshake: The server receives the SYN packet, it must confirm the customer's SYN (ACK=J+1), and also send itself a SYN packet (syn=k), that is, the Syn+ack packet, when the server enters the SYN_RECV state;Third handshake: The client receives the server's Syn+ack packet, sends the acknowledgment packet ack (ACK=K+1) to the server, the packet is sent, the client and the server enter the established state, and the handshake is completed three times.The so-called three-time handshake is a

Due to the improper arrangement of the study plan, the perception of WCF has been stagnant. Recently, I used WCF again in my work. I can see the blog post about duplex communication from instructor Jiang and try it out, accumulate. The original thought of WCF duplex communication is that the original client can call the method of the server, and the server can also call the method of the client. After readi

There are several main ways to communicate threads in a Linux system:* Lock mechanism: Includes mutex, condition variable, read-write lockProcess communication: Pipe: A pipe is a half-duplex mode of communication in which data can flow only one way, and can only be used between processes that have affinity (parent-child processes). In addition, the pipeline transmits an unformatted byte stream, and
