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
A
The number of instructions executed per second doubles
B
The number of instructions executed per second quadruples
C
The number of instructions executed per second is halved
D
The number of instructions executed per second stays the same
Explanation: 

Detailed explanation-1: -The processor, also known as the CPU, provides the instructions and processing power the computer needs to do its work. The more powerful and updated your processor, the faster your computer can complete its tasks. By getting a more powerful processor, you can help your computer think and work faster.

Detailed explanation-2: -The clock speed measures the number of cycles your CPU executes per second, measured in GHz (gigahertz).

Detailed explanation-3: -CPU clock speed is the number of cycles a CPU performs per second. Clock speed is measured in gigahertz (GHz). A higher clock speed indicates a faster CPU. For example, a clock speed of 2.1 GHz equals 2.1 billion cycles per second and a 3.6 GHz CPU can perform 3.6 billion cycles per second.

Detailed explanation-4: -The major types of CPU are classified as single-core, dual-core, Quad-core, Hexa core, Octa-core, and Deca core processor which is explained below.
