MULTIPLE CHOICE QUESTION

30 sec • 1 pt

Which of the following is NOT a factor that directly affects CPU performance?

Cores

Cache size

Processor type

Hard drive capacity

Answer explanation

The hard drive capacity does not directly influence CPU performance. Factors like cores, cache size, and processor type do.

2.

MATCH QUESTION

1 min • 2 pts

Match the components of a CPU to their functions.

Cache

  • Fetch and execute instructions.

  • Data Bus

  • Determine memory locations.

Core

  • Temporarily store frequently used data.

  • Address Bus

  • Transmit instructions and data between components.

Answer explanation

Core fetches and executes instructions, Cache temporarily stores data, the Data Bus transmits information, and the Address Bus determines memory locations.

What is the most likely outcome of increasing a CPU’s clock rate beyond its limit?

Data corruption

Overheating

Increased efficiency

Data corruption and Overheating

Answer explanation

Both data corruption and overheating can occur when clock rates exceed the CPU’s designed limits.

4.

REORDER QUESTION

1 min • 1 pt

Arrange the stages of the fetch-decode-execute cycle in the reverse order.

Decode

Fetch

Execute

Answer explanation

The CPU fetches the instruction first, decodes it to understand it, and then executes the instruction.

OPEN ENDED QUESTION

2 mins • 2 pts

Explain the role of pipelining in CPU performance and mention one of its limitations.

Evaluate responses using AI:

OFF

Answer explanation

Pipelining improves performance by overlapping instruction stages but suffers in scenarios involving branching, causing the pipeline to reset.

7.

MATH RESPONSE QUESTION

1 min • 1 pt

A CPU has a data bus width of 16 bits. How many values can be transmitted at once?

Mathematical Equivalence

ON

Answer explanation

A 16-bit data bus can hold values ranging from 0 to 65535, allowing 65536 different values to be transmitted.
