The CPU is the brain of a computer, containing all the circuitry needed to process input, store data, and output results. The CPU is constantly following instructions of computer programs that tell it which …

There's a central processing unit, or CPU, where all the calculations are done. And finally, there are output devices that take information and convert it into physical output.

At a high level, all computers are made up of a processor (CPU), memory, and input/output devices. Each computer receives input from a variety of devices, processes that data with the CPU and …

Understand hardware, software, CPU, memory, storage devices, and key characteristics of a computer system.

Explore components, memory, microprocessors, and OS to understand how modern computer systems work and have evolved.

How does a computer work? Learn about transistors, logic gates, logic circuits, the CPU, memory, and the file system.

Check your understanding of the flow inside the computer, from the input to the CPU and memory and back to the output, in this set of free practice questions designed for AP Computer Science Principles …

If the device's main purpose is to gather information for the computer, then it's an input device. If its main purpose is to let the computer communicate information to the user, then it's an output device.

Since the CPU is constantly using data from memory, they're connected via a memory bus, a high speed communication transfer system, typically made from wires, conductors, or optical fibers.

- The CPU is the master chip that controls all the other parts of the computer. A CPU needs to do different things, so inside it has smaller, simpler parts that handle specific tasks.
