Process image

A process image is like a snapshot of a computer program when it is running. You know how when you take a picture with a camera, it captures a moment in time and keeps it forever? Well, a process image does the same thing for a computer program.

When a program starts running, it has a lot of information that it needs to keep track of, like variables and memory locations. The process image is like a record of all of that information at that particular moment in time.

Think of it like a coloring book. When you start coloring a picture in a coloring book, you have a blank page and a set of crayons. As you start coloring, the picture comes to life and gets more and more detailed. The process image is like a snapshot of the picture at a particular moment in time, when it is partially colored in but not yet complete.

This process image is important because it can be used to restart the program from that exact point later on, if needed. It's like saving a game in the middle so that you can come back to it later and pick up where you left off.

So, to sum up: a process image is a snapshot of a computer program when it is running, sort of like a picture of a partially-colored coloring book page. It helps to keep track of all the information the program needs and can be used to restart the program from that exact point later on.
