What this article shares with you is about the differences and connections between processes and programs. The editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article. Let's take a look at it with the editor.

The differences between the process and the program are: 1, the process is dynamic, while the program is static; 2, the process has a certain life cycle, but the program is a collection of instructions, and the program itself has no life cycle. Contact: a process is a running activity of a program in a computer about a data set.

Difference:

1. The process is dynamic, while the program is static

2. The process has a certain life cycle, but the program is a collection of instructions, which does not have the meaning of "movement". A program that does not establish a process cannot be recognized by the operating system as an independent unit.

3. A program can correspond to multiple processes, but a process can only correspond to one program.

4. The composition of process and program is different. From a static point of view, a process consists of three parts: program, data and process control block (PCB), and a program is an ordered set of instructions.

Contact:

Process is a running activity of a program in a computer on a certain data set, the basic unit of resource allocation and scheduling of the system, and the basis of the structure of the operating system.

These are the differences and connections between processes and programs, and the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
