3 :- All the logic and mathematical calculations done by computer happen in central processing unit. CPU is generally composed of the main memory, control unit and arithmetic-logic unit. CPU operates other pieces of electronic equipment.
4 :- The speed of computers is usually measured in megahertz (MHz) or gigahertz (GHz).
5:- MEGAPIXELS The quality of image captured by digital camera is measured in megapixel.
The resolution of a digital photo is expressed in terms of "megapixels" which is total number of pixels in the photo. So, a photo that is 2048 pixels x 1536 pixels in size, which is a total of 3,145,728 pixels would have a resolution of 3 megapixels.
6:- internal memory.
Primary memory is also called internal memory whereas Secondary memory is also known as a Backup memory or Auxiliary memory.
