Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A CPU with two cores, called a dual core processor, is like having two processors in one.A dual core processor can fetch and execute two instructions in the same time it takes a single core processor to fetch and execute just one instruction.A quad core processor has four cores and can carry out even more instructions in the same period of time.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The CPU fetches the instructions one at a time from the main memory into the registers. One register is the program counter (pc). The pc holds the memory address of the next instruction to be fetched from main memory.

Detailed explanation-2: -Parallel processing is a method in computing of running two or more processors (CPUs) to handle separate parts of an overall task.

Detailed explanation-3: -This is a technique known as instruction pipelining, and is used in almost all modern general-purpose CPUs. Pipelining allows multiple instruction to be executed at a time by breaking the execution pathway into discrete stages.

Detailed explanation-4: -What Does Dual Core Mean? Dual core is a CPU that has two distinct processors that work simultaneously in the same integrated circuit. This type of processor can function as efficiently as a single processor but can perform operations up to twice as quickly.
