Kernel tasks - spawned threads and spawned processes

[askingquestion]

What is spawned a process meaning:
"organizing and managing threads and the various processes spawned by running applications;"
In more granular terms, accomplishing these three kernel functions involves a range of computer tasks, including the following:

• loading and managing less-critical OS components, such as device drivers;
• organizing and managing threads and the various processes spawned by running applications;

I try to use google and I not understand the meaning.

In the simplest terms, when one software program wants another program to run, it do it in one of two ways. It can "call" it and then wait until it finishes. That type of call is "synchronous" because the caller process does not resume until the called process has completed.

Alternatively, the main process can either "spawn" a thread or another process. It this case, both the parent process and the child process run at the same time.

Spawning a thread simply means that a single process has two execution paths that are sharing the same code base and perhaps other resources.

In some cases "spawning a process" can mean the same thing as spawning a thread. But more often, it refers to one process triggering an entirely different process - with a different executable file.

The most common example of spawning a process is when you run a program or app from your laptop or phone. The GUI that you use to find the right icon and "open" that icon is the parent process. That parent process reds in the file with the new program or app that you have selected and runs it - it "spawns" it. You can see that it continues on after starting your app because if you wish, you can use it to open another app without waiting for the first app to end. That GUI program and the apps that you open with is run asynchronously (without waiting for each other). Each one is a process.
