Past Questions for WAEC Computer Studies Exam
Here are some sample past questions based on highly repeated topics to help you with your exam preparation.
Sample Past Question 1:
Question:
Define database management system (DBMS) and explain its key functions.
Answer:
A DBMS is a software system that manages databases. Key functions include:
- Data Storage: Storing data in a structured format.
- Data Retrieval: Allowing data to be easily accessed and manipulated.
- Data Security: Ensuring that data is protected from unauthorized access.
- Backup and Recovery: Ensuring that data can be restored after a system failure.
Sample Past Question 2:
Question:
Explain the difference between serial and parallel transmission of data.
Answer:
- Serial Transmission: Data is sent one bit at a time over a single channel. It is slower but more efficient for long-distance communication.
- Parallel Transmission: Data is sent multiple bits at a time over multiple channels. It is faster but can experience more interference over long distances.
Sample Past Question 3:
Question:
Write a flowchart to calculate the area of a rectangle with a length of 5cm and a width of 3cm.
Answer:
- Start.
- Declare variables length = 5 and width = 3.
- Calculate area = length * width.
- Output the result: area = 15cm².
- End.
Sample Past Question 4:
Question:
What are the types of network topologies, and how do they differ?
Answer:
- Bus Topology: All devices are connected to a single central cable. It is simple but can become slow with many devices.
- Star Topology: Devices are connected to a central hub. It is reliable but requires more cabling.
- Ring Topology: Devices are connected in a circular fashion. Data travels in one direction, making it efficient but vulnerable to a break in the loop.
- Mesh Topology: Every device is connected to every other device. It is highly reliable but costly.
