If the number of cores goes up from 2 to 4-what is the exact effect on performance?
A
Performance Decreases
B
The maximum number of instructions executed per second doubles
C
The maximum number of instructions executed per second quadruples
D
The maximum number of instructions executed per second is quartered
Explanation: 

Detailed explanation-1: -A CPU that offers multiple cores may perform significantly better than a single-core CPU of the same speed. Multiple cores allow PCs to run multiple processes at the same time with greater ease, increasing your performance when multitasking or under the demands of powerful apps and programs.

Detailed explanation-2: -Faster clock speed means more storage is available for instructions, data and programs.

Detailed explanation-3: -The clock speed measures the number of cycles your CPU executes per second, measured in GHz (gigahertz). In this case, a “cycle” is the basic unit that measures a CPU’s speed.

Detailed explanation-4: -Processor performance can be affected by clock speed, cache size and the number of cores the processor has.
