Instruction pipeline

Okay, so let me tell you about instruction pipelining in a very simple way.

Imagine that you have a lot of toys and you want to keep them in a toy box. Now, you cannot keep all of them at the same time because they will not fit. So, what you do is you keep a few toys in the toy box, and when you need another toy you get it from the shelf and put one of the toys from the toy box on the shelf. This way, you can keep playing with new toys without taking all of them out at once.

Similarly, in a computer, there are many tasks that need to be executed. These tasks are known as instructions. The instruction pipeline is a series of stages that each instruction must go through in order to be executed by the computer's processor.

Now, let's say you want to add two numbers. This requires three steps – fetch the first number, fetch the second number, and add them together. With instruction pipelining, the processor can start executing the first instruction while it is still fetching the second. This reduces the amount of time it takes to execute the instructions, making the computer faster.

To put it simply, instruction pipelining allows the computer to work on multiple instructions at the same time, just like you can play with multiple toys at the same time, without getting confused or overwhelmed.
