The next instruction to be fetched is like the next page in your favorite storybook, it's what comes next in the list of things the computer needs to do.
Imagine you're reading a story, and every time you finish one sentence, you turn the page to see what happens next. That’s kind of how a computer works when it’s running a program. It reads one instruction at a time, like one sentence, then goes to the next instruction, which is like turning the page.
Like a Recipe
Think of a recipe as your storybook. You start with the first step: "Preheat oven to 350°F." That’s the first instruction. The next instruction could be, "Mix flour and sugar." Just like you turn the page in a book, the computer moves on to the next instruction after it finishes one.
The fetch part means the computer is getting ready to read that next instruction, like your finger pointing at the next line of the recipe. It’s simple, just like counting from 1 to 2. No magic needed, just a little bit of order!
