Using Computers: Unit Exam B
Telling hardware from software, file types and file paths, backups, strong passwords and spotting a scam message.
Instructions
- Time allowed
- 25 minutes
- Total marks
- 25
- Calculator
- No calculator is permitted.
- Answer all the questions.
- The number of marks for each question is shown in brackets. Use it as a guide to how much to write.
- The clock at the top counts down from the real time allowed. When it reaches zero the paper is locked and marked, as it would be collected in the exam hall.
- Read every question to the end before answering. Where a question says tick two boxes, tick exactly two: ticking more than asked scores nothing. Type one word and number answers carefully, because they are marked exactly.
Questions
Answer every question, then finish the paper to have it marked. Marking as you go teaches you far less.
Tick one box.
- LB A web browser
Software is a program. A web browser is software; the others are hardware.
| Hardware | Software | |
|---|---|---|
| Monitor | ||
| Windows 11 | ||
| Graphics card | ||
| A spreadsheet program |
Tick one box in each row.
- LMonitor: Hardware
- LWindows 11: Software
- LGraphics card: Hardware
- LA spreadsheet program: Software
Monitors and graphics cards are physical parts. Windows 11 and a spreadsheet program are programs.
| Image | Sound | Text document | Video | |
|---|---|---|---|---|
| .mp3 | ||||
| .png | ||||
| .mp4 | ||||
| .txt |
Tick one box in each row.
- L.mp3: Sound
- L.png: Image
- L.mp4: Video
- L.txt: Text document
.mp3 is sound, .png is an image, .mp4 is video and .txt is plain text.
- LScience
The file sits directly inside the Science folder, which is inside Year 7, which is inside Documents.
- Lforces.docx
The file is forces.docx: the name is forces and the extension is .docx.
Tick one box.
- LA A hierarchy
Folders within folders form a hierarchy.
Tick one box.
- LD On a separate storage device or in cloud storage
A backup must be somewhere separate from the original, so one failure cannot destroy both.
Tick one box.
- LC Close it and tell a teacher or an adult
This is a scam. Do not ring, type anything or download anything: close it and tell an adult.
- LIt is long, for example at least twelve characters
- LIt mixes capital and small letters, numbers and symbols, and is not a word or personal information
A strong password is long, at least twelve characters, and mixes capital letters, small letters, numbers and symbols. It should not be a dictionary word, a name, a birthday or anything else someone could guess.
Tick two boxes.
- LA Using a different password for each account
- LB Locking or logging off the computer when you leave it
- LNo marks if more than 2 boxes are ticked
Lock or log off when you leave, and use a different password for each account, so one leak cannot open them all.
Tick one box.
- LC Undo the last action
Ctrl + Z undoes the last thing you did.
Tick one box.
- LD Checking the spelling in an essay
Spell checking is done by an application such as a word processor, not by the operating system.
- LYou can find it quickly later without opening other files
- LYou know what it contains, so you do not open, hand in or overwrite the wrong file
A descriptive name means you can find the file quickly later without opening every file in the folder, and you can tell what it contains, so you do not hand in or save over the wrong one.
| Input | Output | Storage | |
|---|---|---|---|
| Graphics tablet | |||
| Projector | |||
| External hard drive |
Tick one box in each row.
- LGraphics tablet: Input
- LProjector: Output
- LExternal hard drive: Storage
A graphics tablet sends drawing into the computer, a projector displays output, and an external hard drive stores files.
This is an original Key Stage 3 assessment. Most questions are closed, so the marking is exact, and the written answers are marked against a mark scheme in the same style as a GCSE paper, so the format is familiar long before it counts.
