Multitasking-process issues

1. In the development process, often involves a word, multi-process.

2. First of all, what is called a process?

Suppose, now there is a program called a.py, a.py also has a corresponding static file, then, when started, this program and the static file is called a process. A process is the basic unit for an operating system to allocate resources.

3. What is the process?

First, the process is created by the operating system under human conditions, after creation will be in a ready state, and then will be dispatched some resources, such as logos, pictures and so on. At this point in a running state, as the logic continues to run, you will encounter relative logic, for example, you need to do some logical operation, only when you complete the relative logic operation, the program (process) will continue to go down, as long as there is no action, the process is in a waiting (blocking) state, After waiting for the condition to be satisfied, the wait becomes the ready state, then the corresponding resource is dispatched to reach the running state again, and when all the tasks (requirements) are completed, the process is freed (killed) and the process is finished.

4. The process is performed by the CPU.
