Computer Performance | MCQs

Explanation

Execution time is the time a computer takes to complete a job or instruction.

It measures the duration from the start to the end of processing a task.

It is crucial for evaluating processing speed and efficiency.

Explanation

Hertz (Hz) is the unit used to measure processor speed.

It indicating how many cycles per second the processor can execute.

Modern processors are measured in:

• Megahertz (MHz) - millions of cycles per second
• Gigahertz (GHz) - billions of cycles per second

Explanation

The CPU is the brain of a computer.

It contains all the circuitry needed to process input, store data, and output results.

The CPU is constantly following instructions from computer programs

That tells it which data to process and how to process it.

Explanation

Bus width affects how much data can be transferred at once.

System clock speed controls how fast instructions are processed.

Memory access time determines how quickly data can be read/written.

Explanation

The most significant difference that you should note here is that a calculator just performs arithmetical operations, whereas a computer can carry out arithmetical as well as logical operations.

Thus, a computer can solve highly complex problems.

Explanation

Registers are the fastest means of access for CPU.

Registers are the small memory locations which are present closest to the CPU.
