difference between megabyte and gigabyte
The main difference between the megabyte and the gigabyte is how many bytes they contain. A megabyte contains 220 bytes (1,048,576 bytes) while a gigabyte contains 230 bytes (1,073,741,824 bytes). So considering that, a gigabyte can be composed of 210 megabytes (1024 megabytes). 1024 is the number for every step in the scale. Basically, a kilobyte has 1024 bytes, a megabyte has 1024 kilobytes, and a gigabyte has 1024 megabytes. In usual mathematics, each step is multiplied by 1000 or 103.
