How do computers work exactly?

A computer is an electrical-electronic machine that processes information also can be called as an information processor: it takes in raw information (by raw information we mean binary numbers)(or data) at one end, stores it until it’s ready to work on it, chews and crunches it for a bit, then spits out the results at the other end. All these processes have a name. Taking information in is called input, storing information is called as memory (or storage), chewing information is also known as processing we talked, and spitting out results is known as output.

But before all of these actions to take a part in computers working system, it would need some physical components. As for input keyboard, mouse, camera. As for memory storage units can be listed as hard drives, flash memory discs, usbs. As for processing, we need an central processing unit aka CPU or micro processors.

The first computers were gigantic calculating machines and all they ever really did was “crunch numbers”: solve lengthy, difficult, or tedious mathematical problems. Today, computers work on a much wider variety of problems—but they are all still, essentially, calculations. Everything a computer does, from helping you to edit a photograph you’ve taken with a digital camera to displaying a web page, involves manipulating numbers in one way or another.
