S1 ICT: Computer System Components, Hardware and Software (Paper 1: basics)
This first paper covers the basics only: naming the part each device belongs to, separating hardware from software, and converting capacity with 1 024. Convert the units before you calculate.
Direct answers If a question takes more than a minute, write the part name first and then the number, and it usually works out.

03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | The storage part. | Memory holds data only while it runs; a storage device keeps it long term, so they count as two parts. |
| 2 | The input part. | Anything that feeds data from outside into the computer is input, including a scanner and a webcam. |
| 3 | 1 024 bytes. | Computers work in binary, so the factor is 1 024 rather than 1 000. |
| 4 | The central processing unit; it performs calculations and issues control instructions. | The CPU is the heart of the processing part and its speed in GHz counts the cycles it handles each second. |
| 5 | Data in RAM is lost when the power goes off, while a hard disk keeps data. | A file counts as saved only when it reaches a disk or SSD, so check before shutting down. |
| 6 | 2 048 photos. | 8 times 1 024 divided by 4 gives 2 048, converting to MB before dividing. |
| 7 | The firmware stored in ROM, such as BIOS or UEFI. | Firmware checks the hardware, then loads the operating system from disk into RAM. |
| 8 | Windows is system software and Word is application software. | System software manages hardware and provides a platform, while application software does a specific job for the user. |
| 9 | 2 048 MB. | Multiply by 1 024 to go from GB to MB, and divide by 1 024 the other way. |
| 10 | It mistakes an output part for an input part. | A monitor turns signals into a picture, which is output; only a touch screen also accepts input, and that must be said separately. |
04 What to do after marking
- After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
- Repeat the same item two days later; move to the next paper only when both attempts are correct.
- Parents only need the answer and note columns; there is no need to explain every item.
Three basics: the five parts are input, output, processing, memory and storage; hardware can be touched while software is a program; capacity conversions always use 1 024. Name the part in one sentence first, then write the number.Tutor Registration →
