Okay kiddo, do you know what a computer program is? It's like a set of instructions that tell a computer what to do.
Now, a linear executable is a computer program that has been translated into a format that can be directly executed by a computer's processor. It's like a recipe for the computer to follow.
Think of it like this: Imagine you want to follow a recipe to make cookies, but instead of following the recipe step by step, you just put all the ingredients in a blender and hope for the best. That would be chaotic and messy, right?
In the same way, a linear executable organizes the instructions in a specific order so that the computer can follow them properly, without getting mixed up.
In short, a linear executable is an organized set of instructions for a computer packaged into a format that it can directly understand and execute.
