Processors have a speed measured in

• Hertz

• Bits

• Bytes

• Seconds

Data 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 – what is the exact effect on performance?

• Performance decreases

• The maximum number of instructions executed per second doubles

• The maximum number of instructions executed per second quadruples

• The maximum number of instructions executed per second is halved

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

• The maximum number of instructions executed per second doubles

• 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 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 exact effect on the performance of the computer?

• The maximum number of instructions executed per second doubles

• 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 is quartered

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?

• The number of instructions executed per second doubles

• The number of instructions executed per second quadruples

• The number of instructions executed per second is halved

• The number of instructions executed per second stays the same
