A Correct answer
Explanation

Hardware refers to the physical components of a computer that you can touch and feel - keyboard, monitor, CPU, mouse, etc. Software, programs, and output are intangible - they are instructions or results that run on hardware.

Multiple choice

Transformation of input into output is performed by

  4. The Input-Output unit

  5. The CPU
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

The CPU (Central Processing Unit) is the primary component responsible for processing data. It fetches instructions and data from memory, performs arithmetic and logical operations on them, and stores the results back. This input-processing-output cycle is the fundamental operation of computing. Peripherals provide input/output, memory stores data, but the CPU does the transformation.
