Introduction to Computer Studies as a School Subject
Computer Studies is a subject that introduces students to the basic concepts, components, and applications of computers. It covers topics like computer hardware, software, data processing, and the use of the internet. The subject helps students develop essential skills in typing, word processing, spreadsheets, and basic programming.
By studying Computer Studies, students learn how computers work and how to use them effectively for learning, communication, and problem-solving. The subject also teaches proper computer ethics, safety precautions in computer labs, and how technology can be used responsibly.
Computer Studies prepares students for the modern world, where technology plays a major role in education, business, and everyday life.
The subject is offered by students in Primary school and Junior Secondary School under Basic Science and Technology.

3. Steps involved in program development:
- Problem Definition
- Design Algorithm/Flowchart
- Write Code (Coding)
- Test and Debug
- Documentation
- Maintenance
i. First stage in System Development Cycle:
The first stage is Planning/Feasibility Study, where the project requirements are gathered, and the feasibility of the project is determined in terms of cost, time, and resources.
ii. Systems Analyst Problem-Solving Approach:
- Define the problem: Understand the problem in detail.
- Gather information: Collect data relevant to the problem.
- Analyze the data: Identify issues and break down the problem.
- Design solutions: Create alternative solutions to address the problem.
- Evaluate the solution: Choose the best solution and plan implementation.
4. Explain the following:
I. System: A system is a set of interrelated components working together towards a common goal or purpose.
II. Information System: An information system is a system designed to collect, process, store, and distribute information to support decision-making and operations.
III. Subsystem: A subsystem is a smaller, self-contained system that forms part of a larger system.
5. Steps for the following:
(i) Change Case:
- Select text.
- Use the “Change Case” option (in word processors), or use keyboard shortcuts (e.g., Shift + F3 in MS Word).
(ii) Subscript:
- Select the text.
- Apply subscript formatting (e.g., Ctrl + = in MS Word).
(iii) Superscript:
- Select the text.
- Apply superscript formatting (e.g., Ctrl + Shift + = in MS Word).
Three Methods for File Security:
- Password Protection: Secures files by requiring a password to access them.
- Encryption: Converts files into unreadable formats to prevent unauthorized access.
- Backup: Regularly backing up files to prevent data loss.
6. Methods of Accessing Files:
- Sequential Access: Files are accessed in a linear fashion, one record after another.
- Direct Access: Files can be accessed randomly, without following a sequence.
- Indexed Access: Uses an index to locate files quickly.
i. Types of File Organization Method:
- Sequential Organization: Data is stored in sequence, and records are processed in the same order they were entered.
- Indexed Organization: Data is organized with an index that allows faster searching.
- Hashed Organization: Uses a hashing function to store and retrieve data quickly.
ii. Two Differences between Register and Main Memory:
- Speed: Registers are faster than main memory.
- Size: Registers are smaller in size compared to main memory.
