What is CPU?

What is CPU?

In this generation, everyone knows about Computers. But they don't know about the components of the computer in detail. 

CPU (central processing unit) is not the iron cabinet, it is more that it. CPU is a processing device that is used to do manage every process during working. When the user provides an input to the computer, the CPU takes the process as input and work on it (process) and then provide output. 

In the above picture, you can see the CPU. As we know CPU manages every process of the computer that why CPU also is known as Processor or Micro-Processor.

The processor or CPU divided into three parts:-

1. CU (Control Unit):- Control unit control every processing and devices that are connected to the CPU. And also work for the real-time update, decision making, inputs, outputs everything controlled by the CPU or Processor.

2. ALU (Arithmetic and Logic Unit):- Arithmetic and Logic unit control every process that is related to the calculation or mathematics solution like- addition, subtraction, multiplication, division, etc. and also work for a logical process like- if, else, equals, NOT, AND, etc.  

3. MU (Memory Unit):- Memory unit is not inbuilt in the CPU or processor. Memory unit directly attached to the CPU. All of the processing, inputs, outputs are stored into the memory unit. If the user does not attach the memory unit with the CPU, the computer will not start or boot.

Camera Explanation

Camera... What is a Megapixel?

"A megapixel is a combination of 10 million pixels."

It means that when you talk about the camera and its megapixel you must attract on camera quality. But camera quality does not only depend on the megapixel size, but it also depends on the camera lens, aperture, megapixels size with pixel quality, and processing of the camera.

Today, everyone wants to purchase the camera that has a major megapixel size, but they don't know what is megapixel.

Some companies provide you 12 MP, 32 MP, 64 MP cameras in smartphones. But you actually don't know that the bigger camera can shot the picture with a bigger camera sensor but the quality is not good as the camera megapixel size.

In the above picture, you can see two camera sensors. 1st one is a DSLR 24-megapixel sensor and 2nd is a smartphone's 32-megapixel camera.

 As you know DSLR also shoot the best photos in comparison to smartphones, the reason is that DSLR camera sensor has good quality pixels, approx size is 1.22 micron per pixel or more but smartphone's camera pixel is smaller than the DSLR, that's why  DSLR and some good quality camera provide you excellent picture quality.
