How many bytes are there in a GB, MB?

0 146

Byte is a unit of digital capacity big enough to store a single character of text. Bytes, abbreviated to ‘B’ are sometimes confused with bits: ‘b’. 1 byte is made up of 8 bits, the basic binary units of information.

Nowadays, it is no longer convenient to state the capacity of digital devices in bytes due to their large data storage size. Therefore, the multiples of bytes are commonly used.

There is some confusion about the actual value of the multiples of a byte, such as megabytes or gigabytes. There are two possible interpretations of the prefixes. According to the metric (SI) format:

Kilobyte
1000 B
Megabyte
1000B
Gigabyte
1000B
Terabyte
1000B


However, JEDEC (Joint Electron Device Engineering Council), defines three of the multiples of a byte as:

Kilobyte
1024 B
Megabyte
10242 B
Gigabyte
1024B


This is the most common understanding of the above prefixes used in information technology and computing based on binary system.

To clear up the confusion around prefixes, IEC (International Electrotechnical Commission) proposed the new standard of naming the binary multiples:

Kibibyte
1024 B
Mebibyte
1024B
Gibibyte
1024B
Tebibyte
1024B


Did you know?

Eight bits used to be called an octade.
