Megabyte [MB] is a unit of transferred or stored digital information, which is extensively used in information and computer technology. In SI, one megabyte is equal to 1,000,000 bytes. At the same time, practically 1 megabyte is used as 220 B, which means 1,048,576 bytes. Nowadays, the amount of information measured by megabytes is used for representing the size of a typical MP3 file, the size of a JPEG image, and so on.
Megabyte in SI and base 10 [decimal]
1 Megabyte = 10002 bytes
1 Megabyte = 1,000,000 bytes
Megabyte in base 2 [binary]
1 Megabyte = 220 bytes
1 Megabyte = 10242 bytes
1 Megabyte = 1,048,576 bytes
Gigabyte [GB] is one of the most commonly used units of digital information which is equal to 1,000,000,000 bytes. However, in computer operating science, the value of 1 GB is considered to be equal to 230 or 10243 bytes which is equal to 1,073,741,824 bytes. GB is often used for indicating a size of memory or specifying a size of a movie, computer RAM, and so on. The maximum amount of information stored in a single layer DVD is usually close to 4.8 GB, and the maximum amount of information that can be stored in a single layer Blu-ray disc is equal to 25 GB.

History/origin: The gigabyte is based on the byte, which is derived from the bit, and is a unit that makes use of SI [International System of Units] prefixes. The gigabyte is most commonly understood in terms of its decimal definition of 10003 bytes. There is also however, a binary definition where a gigabyte is 10243 bytes. Because this can be the source of confusion, in 1998, the International Electrotechnical Commission published standards that required the gigabyte strictly denote 10003 bytes. Prefixes to denote the byte being based on 1024 rather than 1000 were also created, with gibibyte referencing 10243 bytes. Despite this effort, the gigabyte is still often used to signify either of these definitions.
Current use: The unit of bytes and all its multiples are used worldwide for data storage. Computer files, hard disks, Blu-ray discs, video games, etc. all store or contain storage space referenced in byte multiples such as kilobytes, megabytes, or gigabytes.
Megabyte
Definition: A megabyte [symbol: MB] is equal to 106 bytes [10002 bytes], where a byte is a unit of digital information that consists of eight bits [binary digits].
History/origin: The megabyte is based on the byte, which is derived from the bit, and is a unit that makes use of SI [International System of Units] prefixes. The prefix "mega" can be ambiguous; the SI use of "mega" would indicate that a megabyte is 1,000,000 bytes, or 10002 bytes, but a base of 1024 [rather than 1000] is also used in information technology as a convenient way to express byte multiples as powers of 2. In 1998, the International Electrotechnical Commission attempted to address this by defining new prefixes to indicate a base of 1024 rather than 1000. Rather than using the prefix "mega," within this system of prefixes, 10242 is referred to as a mebibyte.
Current use: Megabytes are widely used in data storage for file sizes [documents, photos, videos, etc.] as well as for storage devices such as flash drives or, in the past, floppy disks. Today however, storage devices are typically larger, often involving either gigabytes [10003 bytes] or terabytes [10004] of data.
