Execution model

When you play a game or do a puzzle, you have to follow certain rules to make it work. The same thing happens when a computer program runs. The execution model is the set of rules that tells the computer how to run the program and what steps to take in order to complete it.

Think of it like a recipe. When you follow a recipe to make a cake, you have to do things in a specific order. First you mix the dry ingredients together, then the wet ingredients. Then you combine them and pour the batter into a pan before you bake it. Following these steps is like following the execution model for a program.

The computer has to follow specific steps to execute a program. The program is made up of code, which is a set of instructions written in a language that the computer can understand. The computer reads each instruction one by one and carries out the action specified in the instruction.

The execution model also includes things like memory management and how the computer deals with errors or unexpected situations. Imagine you are building a tower out of blocks. You have to make sure the blocks are stacked in the right order and supported so they don't fall. The execution model is like the rules you follow to keep the tower from falling.

In summary, the execution model is a set of rules that a computer follows to run a program. It's like a recipe or rule book that tells the computer what to do in order to complete a task.
