Question

Arrange the following computers in the decreasing order of their cost, speed and size: A. Mini computers, B. Super computers, C. Mainframe computers, D. Micro computers.

• A. C, B, A, D
• B. B, C, D, A
• C. B, C, A, D
• D. C, B, D, A

Hint:

Order by power and size: Super computer, Mainframe computer, Mini computer, Micro computer.

Answer 1

The Correct Option is C

Step 1: Understanding the Question:

• This question requires us to arrange four classes of computers in decreasing order (from highest to lowest) based on their cost, processing speed, and physical size.

• We need to compare the general characteristics of Supercomputers, Mainframes, Minicomputers, and Microcomputers.

Step 2: Detailed Explanation:

• Let us analyze each class of computer based on cost, speed, and size:

• 1. Supercomputers (B): These are the fastest, most powerful, largest, and most expensive computers in the world. They consist of thousands of processors working in parallel and are used for complex scientific tasks like weather forecasting and nuclear research. This is at the top of the hierarchy.

• 2. Mainframe Computers (C): These are highly powerful, large, and expensive multi-user systems. They are optimized for processing massive amounts of transactions and database queries simultaneously, and are widely used by large corporations, banks, and government agencies. They are smaller and less expensive than supercomputers, but larger than minicomputers.

• 3. Minicomputers (A): Also known as mid-range servers, these are smaller and less expensive than mainframes but possess greater processing power than personal computers. They typically support tens to hundreds of users simultaneously.

• 4. Microcomputers (D): These are the smallest, least expensive, and slowest among the four categories. Powered by a single microprocessor, they are designed for single-user tasks (e.g., desktops, laptops, tablets, and smartphones).

• Arranging them in decreasing order (highest/largest to lowest/smallest):

• Supercomputers (B) $\rightarrow$ Mainframe computers (C) $\rightarrow$ Minicomputers (A) $\rightarrow$ Microcomputers (D).

• This matches the sequence: B, C, A, D.

• This corresponds to Option (C).

Step 3: Final Answer:
The correct option is (C).
