DNA Questions:
Q: What is the function of defragmentation in the computer?
A: Defragmentation arranges fragmented files together in an organized manner so they can be easily collected by RAM and sent to the processor for processing, which speeds up the system.
DNA Questions:
Q: Explain how compression is carried out in the computer.
A: Compression reduces file size by identifying repeated patterns of data. Instead of storing every repeated instance, only the first instance is stored along with how many times it repeats.
DNA Questions:
Q: List 2 types of operating systems.
- Single-user operating system (for household appliances)
- Network operating system (controls many computers on a network)
DNA Questions:
Q: List 3 functions of the operating system.
A: Any 3 of: Memory Management, Resource Management, Controlling Input/Output of Data, Error Handling, Security (usernames/passwords/firewalls), Print Spooling
DNA Questions:
Q: What is meant by ‘Application software’?
A: Software that helps users carry out specific tasks that are not related to the operating system. Used to produce digital products or perform tasks.
DNA Questions:
Q: List 3 types of application software and describe each of their functions.
A: Examples:
1. Word Processing - creates documents with text, images, tables;
2. Spreadsheet - performs calculations using formulas/functions;
3. Database - enters, edits, and searches data;
4. Graphics Editing - creates/edits vector graphics;
5. Photo Editing - edits digital photos;
6. Presentation - creates multimedia slides
DNA Questions:
Q: Explain the difference between graphics editing software and photo editing software.
A: Graphics editing software creates or edits vector graphics (scalable drawings). Photo editing software edits and enhances digital photographs and raster images.
DNA Questions:
Q: What applications are used to make something happen in the physical environment?
A: Control applications/control software - used to automate movement of control devices or actuators (such as motors).
DNA Questions:
Q: What is project management software?
A: Software used to help plan and track individual tasks in a project so managers can make efficient use of available resources.
DNA Questions:
Q: What are web browsers?
A: Software used to view web pages (e.g., Google Chrome, Mozilla Firefox).
DNA Questions:
Q: Explain the differences between free software and open-source software.
A: Free software gives users freedom to study, modify, copy, or distribute with no restrictions on use. Open-source software makes the source code available so users can modify how it works or distribute modified/unmodified versions.
DNA Questions:
Q: What is proprietary software?
A: Software marketed and distributed by its owner under a brand name. The owner decides the fee and whether to distribute it. Users cannot access or modify the source code.
DNA Questions:
Q: List 3 reasons for software updates.
Any 3 of:
1. Fixing security vulnerabilities or bugs,
2. Increasing compatibility with newer operating systems,
3. Improving performance and efficiency,
4. Introducing new features,
5. Improving usability
Early Finishers Practice Questions
Q: State what is meant by the term ‘application software’. (1 mark)
A: Software that helps users carry out specific tasks not related to the operating system.
Early Finishers Practice Questions
Q: State three types of utility software. (3 marks)
A: Any 3 of: Backup, Defragmentation, Compression, Formatting
Early Finishers Practice Questions
Q: Describe the role of the operating system. (2 marks)
A: The operating system allows users to control and manage the computer’s hardware. It manages memory, resources, input/output, and error handling.
Early Finishers Practice Questions
Q: Explain the benefit of using compression utilities to archive files. (2 marks)
A: Compression reduces file size by removing redundant data, making files take up less storage space and faster to transfer/download.
Early Finishers Practice Questions
Q: Explain why utility software allows the user to schedule backup processes. (2 marks)
A: Backups can be scheduled to run automatically at times when the system is not in use, ensuring regular backups without user intervention and without disrupting work.
Early Finishers Practice Questions
Q: Describe how presentation software can help a presenter to give a talk. (2 marks)
A: Presentation software allows users to create engaging multimedia content with images, text, animation, and video on slides to illustrate and support the spoken content of a talk.
Early Finishers Practice Questions
Q: Describe one use of control software in a relevant industry. (2 marks)
A: Example: In manufacturing, control software takes input from sensors, makes decisions, and outputs commands to motors/actuators to automate production lines or robotic arms.
Early Finishers Practice Questions
Q: Discuss why a building company might use project management software. (8 marks)
Project management software helps:
- Plan and track tasks
- Allocate tasks to individuals/groups
- Track costs
- Manage timelines/deadlines
- Visualize project progress (Gantt charts)
- Arrange for resources/materials to be delivered on time
- Identify dependencies between tasks
- Make efficient use of available resources
- All critical for construction projects with multiple teams and strict deadlines
Early Finishers Practice Questions
Q: State two reasons for updating software. (2 marks)
Any 2 from:
- Fixing security vulnerabilities or bugs
- Increasing compatibility with newer operating systems
- Improving performance and efficiency,
- Introducing new features
- Improving usability
Early Finishers Practice Questions
Q: State three types of service provided by communication software. (3 marks)
A: Any 3 of:
Web browsers, Email, Social media, SMS, MMS, Instant messaging, Video conferencing, Online gaming
Project Management Software Research Questions
Q: What should you explain about project management software? (Research Task 1)
A: Project management software is used to help plan and track individual tasks in a project, allowing managers to efficiently use available resources, allocate tasks, track costs, and ensure timely delivery.
