FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -In this convention, one thousand and twenty-four megabytes (1024 MB) is equal to one gigabyte (1 GB), where 1 GB is 10243 bytes (i.e., 1 GiB).

Detailed explanation-2: -1024 is 210, the power of 2 which is closest to 1000. So computer engineers used the term gigabyte to denote 1024 megabytes (as well as megabyte for 1024 kilobytes and kilobyte for 1024 bytes), because it was more convenient.

Detailed explanation-3: -1GB is approximately 1, 000MB (megabytes).

Detailed explanation-4: -A terabyte is equal to 1, 024 gigabytes (GB), which itself is equal to 1, 024 megabytes (MB), while a megabyte is equivalent to 1, 024 kilobytes.

Detailed explanation-5: -One Megabyte (MB) is about 1 million bytes (or about 1024 Kilobytes (KB)). One Gigabyte (GB) is about 1 billion bytes, or (1024 Megabytes MB). One Terabyte (TB) is about roughly 1 trillion bytes or 1024 gigabytes (GB).
