Practice Computing System in CS Thinking
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
A complete, functioning combination of hardware, software, and data that processes information and performs tasks.
A computing system is the whole package — the machine, its programs, and the information flowing through it, all working together.
Example 1
easyName the three main components of a computer system and describe what each does.
Example 2
mediumDescribe the fetch-decode-execute cycle that the CPU performs. Why is clock speed relevant?
Example 3
mediumExplain why a computer with a fast CPU but very little RAM might still perform poorly. What would the user experience?
Example 4
hardCompare the computing systems in a smartphone, a laptop, and a data centre server. How do they differ in terms of CPU, memory, storage, and purpose?
