JAMB Computer Studies 2024 questions and answers

1. 1.

   What is the benefit of using a bulleted or numbered list in your document?
   
    

   1. A
      It automatically sorts content in alphabetical order
   2. B
      It prevents spelling and grammar errors in the document

      Correct
   Show answerHide answer

   Answer: D

   Bulleted and numbered lists improve readability and clarity in a document:

   • Bulleted lists group related items that have no particular order.
   • Numbered lists present steps or ranked items in a clear sequence.
   • Both formats break up dense paragraphs and allow readers to scan content quickly.
2. 2.

   What type of ICT is used for immersive gaming solutions?

   1. A
      Cloud Computing
   2. B
      Big Data Analytics
   3. C
      Artificial Intelligence
   4. D
      Virtual Reality (VR)
      Correct
   Show answerHide answer

   Answer: D

   Virtual Reality (VR) is the ICT technology used to create immersive gaming experiences. It places the user inside a simulated three-dimensional environment using a headset and motion sensors.

3. 3.

   Why is it important to be stable, steady, and patient during program development?
    

   1. A
      Stability and patience cause the computer's processor to allocate more resources to the task
   2. B
      Most programming environments detect patience through input timing and reward it with fewer syntax errors
   3. C
      Program development involves complex, multi-step problem-solving that requires careful, methodical thinking to avoid and resolve errors
      Correct
   4. D
      Programming languages require strict physical precision in typing every command character
   Show answerHide answer

   Answer: C

   Program development is a complex, iterative process that demands stability and patience because:

   • Bugs and logic errors are inevitable and often require systematic, step-by-step debugging rather than rushed guesses.
   • Rushing increases the likelihood of overlooking edge cases, writing poorly structured code, or misreading error messages.
   • A methodical, patient approach leads to more reliable, maintainable code and fewer critical errors at later stages.
4. 4.

   What does SSD stand for, and what is its primary advantage?
   
   

   1. A
      Secure System Drive; built-in hardware encryption for all stored data
   2. B
      Static Storage Device; lower manufacturing cost compared to hard drives
   3. C
      Solid State Drive; faster data access speeds with no moving mechanical parts
      Correct
   4. D
      Serial Storage Disk; higher maximum storage capacity per unit
   Show answerHide answer

   Answer: C

   SSD stands for Solid State Drive. Unlike a traditional hard disk drive (HDD), an SSD has no moving mechanical parts.

   • Data is stored in flash memory chips, enabling much faster read and write speeds.
   • SSDs are more resistant to physical shock and consume less power than HDDs.
   • The absence of spinning platters and moving read/write heads is the key source of both the speed advantage and the increased durability.
5. 5.

   What does the '%' operator represent in programming languages?
   
   

   1. A
      Exponentiation
   2. B
      Division
   3. C
      Multiplication
   4. D
      Modulus (remainder after division)
      Correct
   Show answerHide answer

   Answer: D

   The % operator is called the modulus operator. It returns the remainder left over after dividing one integer by another.

   • Example: 10 % 3 evaluates to 1, because 10 divided by 3 gives 3 with a remainder of 1.
   • It is widely used to test whether a number is even or odd, or to wrap values within a fixed range.
6. 6.

   Which type of computer would a small business most likely use for everyday tasks?
   
   

   1. A
      Minicomputer
   2. B
      Mainframe computer
   3. C
      Supercomputer
   4. D
      Personal computer (PC)
      Correct
   Show answerHide answer

   Answer: D

   A personal computer (PC) is designed for individual use and is the most practical choice for everyday business tasks such as word processing, spreadsheets, email, and browsing.

7. 7.

   What is a common security threat that can compromise your computer files?
   
   

   1. A
      Malware (such as viruses and ransomware)
      Correct
   2. B
      Disk defragmentation
   3. C
      Virtual memory management
   4. D
      Disk partitioning
   Show answerHide answer

   Answer: A

   Malware — malicious software — is one of the most common security threats to computer files. It includes:

   • Viruses: self-replicating programs that attach to files and corrupt or delete them.
   • Ransomware: encrypts files and demands payment for the decryption key.
   • Trojans and spyware: steal or damage data without the user's knowledge.
8. 8.

   What does the 'Thesaurus' feature in word processing packages help users with?

   1. A
      Translating the document text into another language
   2. B
      Checking and correcting grammatical errors in sentences
   3. C
      Counting the total number of words in the document
   4. D
      Finding synonyms and antonyms for selected words
      Correct
   Show answerHide answer

   Answer: D

   The Thesaurus feature in word processors such as Microsoft Word helps users find synonyms (words with similar meanings) and antonyms (words with opposite meanings) for a selected word.

   • It is useful for improving writing variety and avoiding word repetition.
   • In Microsoft Word, the thesaurus is accessed via Review → Thesaurus or by right-clicking a word and choosing Synonyms.
9. 9.

   In graphic design, what does the term DPI stand for?

   1. A
      Dots Per Inch
      Correct
   2. B
      Data Print Integration
   3. C
      Digital Pixel Interface
   4. D
      Display Processing Index
   Show answerHide answer

   Answer: A

   DPI stands for Dots Per Inch. It is a measure of the resolution of a printed or digital image, indicating how many individual ink dots fit within one inch.

   • A higher DPI produces a sharper, more detailed image when printed.
   • Standard print quality is typically 300 DPI; screen display is often 72–96 DPI.
   • DPI is commonly used alongside PPI (Pixels Per Inch), which refers specifically to digital screen resolution.
10. 10.

    What is the purpose of the design phase in program development?
    
    

    1. A
       To write the actual source code of the program
    2. B
       To test the completed program for errors and fix defects
    3. C
       To plan the structure, logic, and interface of the program before coding begins
       Correct
    4. D
       To write the technical documentation for the completed program
    Show answerHide answer

    Answer: C

    The design phase in program (or software) development focuses on planning how the program will be built before any code is written.
