Main memory[ edit ] Early computers used one of two addressing methods to access the system memory; binary base 2 or decimal base By the mids, binary addressing had become the standard architecture in most computer designs, and main memory sizes were most commonly powers of two.

This is the most natural configuration for memory, as all combinations of their address lines map to a valid address, allowing easy aggregation into a larger block of memory with contiguous addresses.

Early computer system documentation would specify the memory size with an exact number such as, or words of storage.

These are all powers of twoand furthermore are small multiples ofor As storage capacities increased, several different methods were developed to abbreviate these quantities.

The method most commonly used today uses prefixes such as kilo, mega, giga, and corresponding symbols K, M, and G, which the computer industry originally adopted from the metric system. The International System of Units does not define units for digital information but notes that the SI prefixes may be applied outside the contexts where base units or derived units would be used.

But as computer main memory in a binary-addressed system is manufactured in sizes that were easily expressed as multiples ofkilobyte, when applied to computer memory, came to be used to mean bytes instead of This usage is not consistent with the SI.

Compliance with the SI requires that the prefixes take their based meaning, and that they are not to be used as placeholders for other numbers, like This style was used from about to In discussions of binary-addressed memories, the exact size was evident from context.

For memory sizes of "41K" and below, there is no difference between the two styles. Capitalization of the letter K became the de facto standard for binary notation, although this could not be extended to higher powers, and use of the lowercase k did persist.

The symbols Kbit, Kbyte, Mbit and Mbyte started to be used as "binary units"—"bit" or "byte" with a multiplier that is a power of —in the early s.

Disk drives[ edit ] The disk drive industry followed a different pattern. Industry practice, more thoroughly documented at Timeline of binary prefixes and continuing today, is generally to specify hard drives using prefixes and symbols with decimal meaning as described by SI.

Unlike computer main memory, there is nothing in a disk drive that causes, or even influences, the capacity to be an integer multiple of a power of For example, the first commercially sold disk drive, the IBMhad 50 not 32 or 64 physical disk "platters" containing a total of 50, sectors of characters each, for a total quoted capacity of "5 million characters.

Since the block headers occupied space, the usable capacity of the drive was dependent on the block size. Blocks "records" in IBM's terminology of 88, 96, and were often used because they related to the fixed block size of and character punch cards.

The drive capacity was usually stated under conditions of full track record blocking. For example, the megabyte disk pack only achieved that capacity with a full track block size of 13, bytes.

Log in Computer Science vs. A question I have gotten a lot lately has to do with the differences and similarities between Computer Science and Computer Engineering.

Floppy disks for the IBM PC and compatibles quickly standardized on byte sectorsso two sectors were easily referred to as "1K". When the High Density "1. In contrast, hard disk drive manufacturers used "megabytes" or "MB", meaning bytes, to characterize their products as early as Many later drives in the personal computer market used 17 sectors per track; still later, zone bit recording was introduced, causing the number of sectors per track to vary from the outer track to the inner.

Nor are drives required to have a number of active surfaces that is a power of, or even divisible by, two; drives with e.

All of these factors reduce the utility of the customary binary prefixes for expressing drive capacity. Today, the hard drive industry continues to use decimal prefixes for drive capacity as well as for transfer rate. Operating systems such as Microsoft Windows that display hard drive sizes using the customary binary prefix "GB" as it is used for RAM would display this as " On the other hand, macOS has since version Previous versions of Mac OS X used binary prefixes.

However, other usages still occur. For example, in one document, Seagate specifies data transfer rates of some of its hard drives in both IEC and decimal units.

Similarly, digital information transfer rates are quoted using decimal prefixes: In the s, as capacities of both types of devices increased, the SI prefix G, with SI meaning, was commonly applied to disk storage, while M in its binary meaning, became common for computer memory.

In the s, the prefix G, in its binary meaning, became commonly used for computer memory capacity. However, many exceptions exist. Because both the SI and "binary" meanings of kilo, mega, etc. The relative difference between the values in the binary and decimal interpretations increases, when using the SI prefixes as the base, from 2.A question I have gotten a lot lately has to do with the differences and similarities between Computer Science and Computer Engineering.
