ancient Web service, and the development and evolution of Apache has been pursued to do this, and it tries to continuously reduce the amount of memory that the service occupies to support greater concurrency. From the perspective of the evolution of Apache's work model, let's take a look at how they optimize memory issues.1. Prefork MPM, multi-process operation modePrefork is the most mature and stable mod

Evolution of Javaweb Program architecture modelOlder programmers have generally experienced the evolution of the Web program architecture pattern, from the very beginning of the development of JSP or Jsp+servlet, to the later MVC, three layers and so on. And now a lot of people have learned the web, probably did not use JSP or Jsp+servlet developed projects, directly learn to use spring, Spring Boot or SPRI

technology and efficiency and the ideal brain computer interface There is a huge gap, but already in our role as a smart assistant. Therefore, we can use the current widely used search engine as the future advanced brain-computer interface of the embryonic or initial state, in other words, the current search engine is currently the most promising to evolve into a brain-computer interface, the realization of artificial intelligence of the Internet service form. Ii. the necessary factors for the
