What is the difference between processor and cpu

The computer architecture helps to determine whether the CPU can process 32bit or 64bit instructions. The clock speed indicates the number of instructions the CPU can process within a second. The execution time for the CPU to execute a program can be calculated using the following formula.

A core is an execution unit of a CPU. This unit is capable of reading and executing instructions. CPU or the processor can have a single core or multiple cores. When a system has more cores, it is called a multicore system.

A CPU with two cores is called a dual-core processor. A CPU with four cores is called a quad-core processor. When there are multiple cores in a single CPU, it can receive many instructions and execute them on separate cores simultaneously. It increases the processing speed. It also implements parallel computing. The internal working of a microprocessor depends on the design and purpose of the microprocessor.

It is limited by number of transistors that can be placed on the chip, the number of package terminations that can connect the processor to the other parts of the computer, the number of interconnections possible and the amount of heat that the chip generates.

In short, the microprocessor is a set of circuits that connect the rest of the computer to the CPU, allowing the system to execute directions.

Many microprocessor also exist without CPUs attached to it. Due to the similarity in usage, it is easy to understand why both of these words have become synonymous. If a person were to refer to a microprocessor as a CPU and vice-versa, it would be acceptable. Difference between CPU and Microprocessor. Image Courtesy: en. Comments Interested. Thank you your information gives light. The CPU would figure out the answer and send it to the program via the southbridge and then to the graphics system, so it may be displayed on the screen, via the northbridge.

This is a very basic example, but it serves to illustrate the separation of the two components. In the above example, the processor calculated and the chipset was a courier. When the pieces of information needed to move around the system, the chipset facilitated the movement. When information needed processing, it was done entirely by the CPU. The functions of a chipset and a CPU are very specific with next to no overlap. Please enter the following code:. Login: Forgot password?
