Detailed Solution for Olympiad Test Level 2: Fundamentals of Computer - 1 - Question 1

The image of an abacus is represented by option A.
Explanation:
Abacus is a counting tool that is used for performing arithmetic calculations. It consists of a rectangular frame with rods or wires, on which beads are placed. The position of the beads on the rods represents different numerical values.
To identify the image of an abacus, we can analyze the options provided:
Option A:
- The image shows a rectangular frame with rods or wires.
- The rods have beads placed on them, which can be moved back and forth.
- The arrangement of the beads on the rods represents numerical values.
Option B:
- The image shows a set of colorful blocks arranged in a pattern.
- It does not resemble the structure of an abacus.
Option C:
- The image shows a collection of colored pencils.
- It does not resemble the structure of an abacus.
Option D:
- The option states "None of these," indicating that none of the provided images represent an abacus.
Therefore, the correct image of an abacus is represented by option A.

The working of Central Processing Unit (CPU) is compared with which of the following organs of human body?

Detailed Solution for Olympiad Test Level 2: Fundamentals of Computer - 1 - Question 2
The working of Central Processing Unit (CPU) is compared with which of the following organs of human body?
Answer: B - Brain
Detailed
The Central Processing Unit (CPU) is the main component of a computer system that performs most of the processing inside the computer. It carries out instructions of a computer program by performing basic arithmetic, logical, control, and input/output (I/O) operations. The working of the CPU can be compared to the functioning of the human brain. Here's how:
1. Processing Power: Both the CPU and the brain are responsible for processing information and making decisions. They have the ability to interpret and execute instructions.
2. Control Unit: The CPU's control unit is like the brain's command center. It coordinates and manages the operations of other components in the computer, just like the brain controls the functions of the body.
3. Arithmetic and Logic Unit (ALU): The ALU in the CPU performs arithmetic and logical operations on data. Similarly, the brain processes and analyzes information, making logical connections and performing calculations.
4. Memory: The CPU uses cache memory to store frequently accessed data, similar to how the brain stores information in short-term memory. Both also have long-term memory storage capabilities.
5. Input and Output: The CPU interacts with input and output devices to receive and send data, just as the brain receives sensory information from the body and sends signals to control movements and actions.
6. Speed and Efficiency: The CPU performs calculations and processes data at incredible speeds, similar to the brain's ability to process information rapidly and efficiently.
In conclusion, the working of the CPU can be compared to the functioning of the brain due to their similar roles in processing information, making decisions, and controlling various operations.
