CPU Clock Cycle Quiz

What is a clock cycle in a CPU?

• The time taken for a program to execute

• The time interval between two consecutive pulses of the clock signal

• The number of instructions executed per second

• The amount of memory used by a program

Which unit is commonly used to measure clock frequency?

• Watts

• Joules

• Hertz

• Ohms

If a processor has a clock frequency of 3GHz, what is the duration of one clock cycle?

• 3 seconds

• 3 milliseconds

• 0.33 nanoseconds

• 3 microseconds

How does increasing the clock frequency affect the CPU's performance?

• Decreases power consumption

• Increases the number of instructions executed per second

• Reduces heat generation

• Slows down the CPU

What is the relationship between clock cycle duration and clock frequency?

• They are directly proportional

• They are inversely proportional

• They are equal

• They are unrelated

Which of the following instructions typically requires more clock cycles?

• MOV

• ADD

• MUL (multiply)

• NOP (no operation)

In assembly language, what does the instruction 'NOP' do?

• Performs an addition

• Fetches data from memory

• Does nothing and just advances the clock cycle

• Jumps to a new address

What is the term for the number of clock cycles an instruction takes to execute?

• Clockspeed

• Cycletime

• Latency

• Cycle count

Which component in a CPU generates the clock signal?

• ALU (Arithmetic Logic Unit)

• Clock generator

• Register

• Cache

If a processor executes an instruction in 2 clock cycles and the clock frequency is 1GHz, how long does the instruction take to execute?

• 2 seconds

• 2 nanoseconds

• 2 microseconds

• 2 milliseconds
