Using Computers: Unit Exam A
Hardware and software, input and output devices, files, folders and file extensions, and keeping your account safe.
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 keyboard
Hardware is the physical equipment you can touch. A keyboard is hardware; the other three are software or data.
Tick one box.
- LD An operating system
System software runs the computer itself. The operating system is the main example; the others are applications.
| Input | Output | |
|---|---|---|
| Microphone | ||
| Printer | ||
| Speaker | ||
| Webcam |
Tick one box in each row.
- LMicrophone: Input
- LPrinter: Output
- LSpeaker: Output
- LWebcam: Input
Input devices put data into the computer: a microphone and a webcam. Output devices bring results out: a printer and a speaker.
- Lfile extension
The .docx part is the file extension. It tells the computer which kind of file it is and which program opens it.
Tick one box.
- LC An image editor
.jpg is an image file, so it opens in an image viewer or editor.
Tick two boxes.
- LA science-forces-homework.docx
- LB y7-science-forces-hw.docx
- LNo marks if more than 2 boxes are ticked
A good file name says what the file contains, so you can find it without opening it. new1 and untitled say nothing.
| True | False | |
|---|---|---|
| Maths is a subfolder of School | ||
| School is stored inside Science | ||
| A file can be saved inside the Maths folder | ||
| A folder can only hold files, never other folders |
Tick one box in each row.
- LMaths is a subfolder of School: True
- LSchool is stored inside Science: False
- LA file can be saved inside the Maths folder: True
- LA folder can only hold files, never other folders: False
Folders inside folders make a hierarchy. Maths and Science are subfolders of School, and any folder can hold files and other folders.
- Loperating system
OS stands for operating system.
Tick one box.
- LD Blue!Tiger7#Mug
A strong password is long and mixes capital letters, small letters, numbers and symbols, and is not a word or a name and date.
- LSomeone else could use your account and it would look like you did it
- LSomeone could read, change or delete your work, or send messages as you
Anything done on your account looks as if you did it, so someone could get you into trouble. They could also read, change or delete your work, or send messages pretending to be you.
Tick one box.
- LA To manage the computer's hardware and run other programs
The operating system controls the hardware, manages files and memory, and lets you run applications.
- L3
Monitor, printer and headphones are output devices. A mouse and a scanner are input devices.
- LIt is easier and quicker to find files later
- LFiles are organised by subject or topic, so there is less risk of losing or overwriting work
Folders organise files by subject and topic, so each file is quick to find later. With everything on the desktop, files get mixed up and it is easy to open, hand in or overwrite the wrong one.
Tick one box.
- LC On a server, so it can be opened from any school computer
A network drive is storage on a server. Any computer on the school network can reach it after you log in.
Tick one box.
- LA Save the file
Ctrl + S saves. Ctrl + Z undoes, Ctrl + A selects all and Ctrl + P prints.
Tick one box.
- LD A hard disk drive
A hard disk drive is storage: it keeps data with the power off. RAM is cleared when the power goes.
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.
