Units of Storage Spaces

Discussing about the units of storage devices which are used in computer systems. You might also be having hard disks, CDs, DVDs, pendrives and many more to go. Here, we will be discussing about the storage space they possess and it’s units of measurement.Bit Representation

Historically, a byte was the number of bits used to encode a single character of text in a computer and for this reason it is the basic addressable element in many computer architectures. The term byte was coined by Dr. Werner Buchholz in July 1956, during the early design phase for the IBM Stretch computer. The de facto standard of eight bits is a convenient power of two permitting the values 0 through 255 for one byte. With ISO/IEC 80000-13, this common meaning was codified in a formal standard. The term octet was defined to explicitly denote a sequence of 8 bits because of the ambiguity associated at the time with the term byte.

Summarizing the basic units as:

1 Bit = Binary Digit
8 Bits = 1 Byte
1024 Bytes = 1 Kilobyte
1024 Kilobytes = 1 Megabyte
1024 Megabytes = 1 Gigabyte
1024 Gigabytes = 1 Terabyte
1024 Terabytes = 1 Petabyte
1024 Petabytes = 1 Exabyte
1024 Exabytes = 1 Zettabyte
1024 Zettabytes = 1 Yottabyte
1024 Yottabytes = 1 Brontobyte
1024 Brontobytes = 1 Geopbyte
