What does a process have to do with a thread? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

The relationship between threads and processes: each process has a corresponding thread, which is actually a series of threads when executing the program. The process is the smallest unit of resource allocation, and the thread is the smallest unit of program execution.

Fundamental difference: the process is the smallest unit of resource allocation, and the thread is the smallest unit of program execution. When the computer executes the program, it will create the corresponding process for the program, and when allocating resources, it will allocate the corresponding process as the unit. Each process has a corresponding thread, which is actually a series of threads when executing the program.

Address space: a process has its own independent address space, and every time a process is started, the system allocates address space for it and establishes a data table to maintain code segments, stack segments and data segments; threads of the same process share the address space of the process.

Resource ownership: resources between processes are independent; threads within the same process share the resources of the process.

Execution process: each independent process has an entry for program execution, a sequential execution sequence and a program entry. However, threads cannot execute independently and must be stored in the application, which provides multiple thread execution control.

Threads are the basic unit of processor scheduling, but processes are not. Because the process of program execution is actually the execution of specific threads, then the processor also deals with the corresponding threads of the program, so the basic unit of processor scheduling is threads.

The answer to the question about the relationship between process and thread is shared here. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
