Free Computer Fundamentals MCQs with Answers

191. Who is the founder of IBM Company?

• A. Nolan Bushnell
• B. Steve Jobs
• C. Thomas J. Watson
• D. Bill Gates

Explanation: Thomas J. Watson Sr. is commonly identified in general computer MCQs as the founder or key builder of IBM. IBM technically developed from the Computing-Tabulating-Recording Company, so the wording simplifies its corporate history.

192. Which of the following types of memory improves processing by acting as a temporary high-speed holding area between the memory and the CPU?

• A. RAM
• B. ROM
• C. EPROM
• D. Cache memory
• E. Flash memory

Explanation: Cache memory is a small, very fast storage area between the CPU and main memory that keeps frequently needed data and instructions close to the processor. RAM is also temporary memory, but it is larger and slower than cache.

193. Which device is used to process data?

• A. CPU
• B. RAM
• C. DCU
• D. VDU

Explanation: The CPU processes instructions and data by performing calculations and controlling computer operations. RAM stores working data, while a VDU displays output and DCU is not the standard name for the main processing device.

194. Rearranging data in a new sequence is known as__________?

• A. Uploading
• B. Updating
• C. Sorting
• D. Summarizing

Explanation: Sorting rearranges records or data items into a chosen sequence, such as alphabetical or numerical order. Updating changes existing data, while summarizing condenses it.

195. Vector graphics is composed of_____________?

• A. Pixels
• B. Paths
• C. Palette
• D. None of above

Explanation: Vector graphics are defined by paths made from lines, curves, and mathematical coordinates, so they can be resized without losing quality. Pixels are the basic elements of raster graphics.

196. In which generation Computers vacuum tube were used?

• A. First generation
• B. Second generation
• C. Third generation
• D. Fourth generation

Explanation: First-generation computers used vacuum tubes for electronic switching and processing. Later generations replaced them with transistors, integrated circuits, and microprocessors.

197. The proper definition of a modern digital computer is____________?

• A. An electronic automated machine that can solve problems involving words and numbers
• B. A more sophistic and modified electronic pocket calculator
• C. Any machine that can perform mathematical operations
• D. A machine that works on binary code

Explanation: A digital computer is an electronic, programmable machine that processes words, numbers, and other data automatically according to instructions. Merely performing arithmetic or using binary code does not fully define a modern computer.

198. Who invented Slide Rules?

• A. John Napier
• B. William Oughtred
• C. Gottfried Leibnitz
• D. Blaise Pascal

Explanation: William Oughtred invented the slide rule by developing a calculating instrument based on logarithmic scales. John Napier invented logarithms, which made the slide rule possible, but not the slide rule itself.

199. Serial access memories are useful in applications where:

• A. Data consists of numbers
• B. Short access time is required
• C. Each stored word is processed differently
• D. Data naturally needs to flow in and out in serial form

Explanation: Serial-access memory is suitable when information naturally enters and leaves one bit or word after another in sequence. It is not preferred when each word needs rapid independent access.

200. Identify the true statement about computer.

• A. Computers are 100% accurate but it can suffer from GIGO (Garbage In Garbage Out)
• B. Computers are reliable because they use electronic component which have very low failure rate
• C. Computer is never tired and does not suffer from boredom
• D. All of above

Explanation: All three statements describe standard computer characteristics: electronic components make computers reliable, they do not get tired, and their accuracy depends on correct input because of GIGO. Therefore, all of the listed statements are true.
