Processors have a speed measured in:

• Seconds

• Bytes

• Bits

• Hertz

Which processor speed is the fastest?

• 4GHz

• 100MHz

• 300Hz

• 16Hz

What doesn’t affect the performance of the computer?

• Cache size

• Number of cores

• Clock speed

• The number of instructions in the program

If the number of cores goes up from 2 to 4, what is the potential effect on performance?

• Larger programs can be executed

• Performance decreases

• The maximum number of instructions executed per second decreases

• Instructions can be executed simultaneously

If the processing speed goes up from 1GHz to 4GHz, what is the potential effect on the performance of the computer?

• The maximum number of instructions executed per second quadruples

• The maximum number of instructions executed per second doubles

• The maximum number of instructions executed per second is halved

• The maximum number of instructions executed per second is quartered

If the processing speed goes up from 2GHz to 4GHz and the number of cores goes from 2 to 4, what is the potential effect on the performance of the computer?

• The maximum number of instructions executed per second is halved

• The maximum number of instructions executed per second quadruples

• The maximum number of instructions executed per second is quartered

• The maximum number of instructions executed per second doubles

If the processing speed goes from 1GHz to 4GHz and the processor is changed from an 8 core to a dual core processor, what is the potential effect on the performance of the computer?

• The number of instructions executed per second stays the same

• The number of instructions executed per second is halved

• The number of instructions executed per second quadruples

• The number of instructions executed per second doubles

If the processing speed goes up from 2GHz to 4GHz and the number of cores goes from 1 to 2, what is the potential effect on the performance of the computer?

• Doubled

• Quadrupled

• Eight times faster

• Sixteen times faster

If the processing speed goes up from 2GHz to 4GHz and the number of cores goes from 1 to 4, what is the potential effect on the performance of the computer?

• Eight times faster

• Quadrupled

• Doubled

• Sixteen times faster

If the processing speed goes up from 1GHz to 4GHz and the number of cores goes from 1 to 8, what is the potential effect on the performance of the computer?

• Sixty four times faster

• Thirty two times faster

• Sixteen times faster

• Eight times faster
