Arithmetic logic unit

An arithmetic logic unit (ALU) is like a little brain inside a computer that helps it do math problems and make decisions. Just like you use your fingers to count and figure out problems, the ALU uses tiny circuits to help the computer add, subtract, multiply, or divide numbers.

But the ALU can do even more than basic math. It can also compare numbers to see which one is bigger or smaller, and it can help the computer make decisions based on these comparisons. For example, it might decide whether to turn on a light based on whether it's dark outside or not.

The ALU is made up of several different parts, each with a specific job. One part might help with addition, another with subtraction, and so on. These parts work together like a team to help the computer solve even the most complex math problems.

Without the ALU, computers couldn't do much more than simple tasks like playing audio or displaying pictures. But thanks to this clever little unit, they can solve problems, make logical decisions, and even play games with us.
