Fetch Execute Cycle
It is the process by which a computer retrieves a program instruction from its memory, determines what actions the instruction dictates, and carries out those actions.
8 of 14
Program Counter
Its job is to have the first instruction of the fetch execute cycle
9 of 14
MAR
Memory Address Register,Stores the current instruction or data being execute
10 of 14
IAR
Instruction Address Registor,Holds the current instruction being executed
11 of 14
Clock Speed
Measured in Cycles per second,1 cycle = 1 Hertz,makes it seem computer is doing multiple tasks at once ,faster the clock speed the quicker the computer is
12 of 14
Cache Size
Extremely fast,The use of cache memory can greatly reduce processing time ,greater cache size = quicker processing time
13 of 14
Number of Cores
Processors,More processors means faster processing speed
