Seeing the Result

Explain output devices and soft copy.

Can you touch the words or pictures inside a computer screen? No! We use Output Devices to display the result of the computer's processing so we can see or hear them.

The Brain in the Box

Explain the CPU and its location.

People often point to the large, rectangular box next to a desktop computer and call it the CPU. But that's a common mistake! That outer case is actually called the System Unit.

Three Parts of the Brain

Explain ALU, CU, and MU.

Key Takeaway: The CPU's Three Parts

The Central Processing Unit is divided into three distinct parts to handle processing tasks efficiently:

ALU

Arithmetic Logic Unit

Performs mathematical calculations and data comparisons.

Control Unit

Controls and directs the flow of data and information.

Memory Unit

Holds data and the final results of processing temporarily.
