Processors have a speed measured in

• Hertz
• Bits
• Bytes
• Seconds

Dara and Instructions in use are stored in the

• Processor
• Embedded system
• Hard disk drive
• Main memory

Typical processor speed of 2016:

• 16Hz
• 100MHz
• 4GHz
• 300GHz

What doesn't affect the performance of the computer

• Clock speed
• Number of cores
• Cache size
• The number of instructions in the program

If the number of cores goes up from 2 to 4 - whaty is the exact effect on performance?

• Performance decreases
• The maximum number of instuctions executed per second doubles
• The maximum number of instructions executed per second quadruples
• The maximum number of instructions executed per second halves

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

• The maximum number of instructions executed per second doubles
• The maximum number of instuctions executed per second quadruples
• The maximum number of instructions executed per second quartered
• The maximum number of instructions executed per second halves

If the clock speed goes up from 2GHz to 4GHz, the number of cores goes from 2 to 4, what is exact effet on the performance of the computer?

• 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
• The maximum number of instructions executed per second halves

If clock speed changes from 1GHz to 4GHz and the number of cores changes from 8 to dual core, what is the exact effect on the performance of the computer?

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