Detailed explanation-1: -Answer. One kilobyte is 1, 024 bytes and it is represented as KB, or more informally as K. One megabyte is equivalent to 1, 024 KB, and one gigabyte is 1, 024 MB. We use these units (KB, MB, GB) to describe the RAM memory, the storage capacity of disks and the size of any application or document.
Detailed explanation-2: -1 MB is 1, 024 kilobytes, or 1, 048, 576 (1024x1024) bytes, not one million bytes. Similarly, one 1 GB is 1, 024 MB, or 1, 073, 741, 824 (1024x1024x1024) bytes. A terabyte (TB) is 1, 024 GB; 1 TB is about the same amount of information as all of the books in a large library, or roughly 1, 610 CDs worth of data.
Detailed explanation-3: -1 kilobyte (KB) = 1024 bytes. 1 megabyte (MB) = 1024 kilobytes. 1 gigabyte (GB) = 1024 megabytes. 1 terabyte (TB) = 1024 gigabytes. 1 petabyte (PB) = 1024 terabytes.
Detailed explanation-4: -The term ‘kilobyte’ has traditionally been used to refer to 1024 bytes (210 B). The usage of the metric prefix kilo for binary multiples arose as a convenience, because 1024 is approximately 1000.
Detailed explanation-5: -1, 024 TB = 1 petabyte (PB). This is equivalent to about 1.5 million CD-ROMs worth of data. 1, 024 PB = an exabyte (EB).
