Why can computers do many things at once?
Imagine you're cooking dinner while listening to a podcast and texting a friend. You can do all these tasks without missing a beat because you're multitasking.
Computers use a technique called "speculative execution" to predict what they might need to do next and start working on it while still doing other tasks. This way, they can do many things at once without waiting for one task to finish before starting another.
Example
If you're halfway through a recipe when you remember you need to text your friend, your brain can start typing the message while still following the recipe.
Remember this
Speculative execution allows computers to multitask efficiently.
