If the number of cores goes up from 2 to 4 – what is the exact effect on performance? (1-4)

• Performance decreases
• 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 doubles

If the processing speed goes up from 1GHZ to 4GHZ – what is the exact effect on the performance of the computer? (1-4)

• The maximum number of instructions executed per second is quartered
• The maximum number of instructions executed per second quadruples
• The maximum number of instructions executed per second is halved
• The maximum number of instructions executed per second doubles

If the processing speed goes up from 2GHZ to 4GHZ and the number of cores goes from 2 to 4 – what is the exact effect on the performance of the computer? (5-6)

• The maximum number of instructions executed per second is halved
• The maximum number of instructions executed per second doubles
• The maximum number of instructions executed per second is quartered
• The maximum number of instructions executed per second quadruples

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 exact effect on the performance of the computer? (5-6)

• The number of instructions executed per second stays the same
• The number of instructions executed per second quadruples
• The number of instructions executed per second doubles
• The number of instructions executed per second is halved
