People used to do programming only with machine language. The electric current can flow through all the gates that are on and whatever path the current takes makes it do something on the computer (ie make the screen light up a certain way, add some numbers, or send a message) The ones and zeros specify if certain “gates” in the hardware of the computer are either on or off. It basically looks like a bunch of ones and zeroes. When you run the code, what is actually happening is that the words you type are converted into binary code (also called machine language). However computers can’t understand words and number that are used in programming. So, computer programmers give the computer instructions on how to do that in their programs. People have to program it to respond to user interaction with a mouse and keyboard, show different things on the screen, and access the internet. Without being programmed, a computer would be useless.
