Traditional client and server-side software technologies use a software solution called sockets to establish a connection.

As a result, this technology becomes difficult to understand, not to mention a comprehensive understanding of how sockets are used in the enterprise, or how they are used in conjunction with mobile and cloud technologies. This article will help you understand the concept of sockets, the type of sockets you can use for your applications, and use in mobile and cloud solutions ...

In the past, we have introduced some principles of software development, such as the 10 commandments of high quality code and the UNIX design principles described in the UNIX legend (next article). I believe that you can learn from middle school some knowledge of design principles, as I said in the "How Do I Recruit procedures", a good programmer usually consists of its operational skills, knowledge level, experience level and ability four aspects. Here I would like to talk about some of the principles of design, I think these things belong to the long-term experience summed up knowledge.
