– equivalent to 1 "word" on 32-bit processors, including those for the Apple Macintosh, Pentium-based PC, PlayStation, GameCube, Xbox, Wii. 36 bits – size of word on Univac 1100-series computers and Digital Equipment Corporation's PDP-10 56 bits (7 bytes) – cipher strength of the DES encryption standard 2 6: 64 bits (8 bytes)
In this era, bit groupings in the instruction stream were often referred to as syllables [a] or slab, before the term byte became common. The modern de facto standard of eight bits, as documented in ISO/IEC 2382-1:1993, is a convenient power of two permitting the binary-encoded values 0 through 255 for one byte, as 2 to the power of 8 is 256. [8]
When b is 2, the unit is the shannon, equal to the information content of one "bit". A system with 8 possible states, for example, can store up to log 2 8 = 3 bits of information. Other units that have been named include: Base b = 3 the unit is called "trit", and is equal to log 2 3 (≈ 1.585) bits. [3] Base b = 10
One zettabyte is equal to one sextillion bytes or 10 21 (1,000,000,000,000,000,000,000) bytes, or, one zettabyte is equal to a trillion gigabytes. [ 4 ] [ 2 ] To put this into perspective, consider that "if each terabyte in a zettabyte were a kilometre, it would be equivalent to 1,300 round trips to the moon and back (768,800 kilometers)". [ 4 ]
In information theory, one bit is the information entropy of a random binary variable that is 0 or 1 with equal probability, [3] or the information that is gained when the value of such a variable becomes known. [4] [5] As a unit of information or negentropy, the bit is also known as a shannon, [6] named after Claude E. Shannon.
In this convention, one thousand and twenty-four megabytes (1024 MB) is equal to one gigabyte (1 GB), where 1 GB is 1024 3 bytes (i.e., 1 GiB). Mixed 1 MB = 1 024 000 bytes (= 1000×1024 B) is the definition used to describe the formatted capacity of the 1.44 MB 3.5-inch HD floppy disk , which actually has a capacity of 1 474 560 bytes .
19. Get your sleep. One great thing about being 50—you are completely over the social pressure to stay out late. (Though hormonal changes from menopause can have you staring at the ceiling at 2 ...
The byte is the most common unit of measurement of information (megabyte, mebibyte, gigabyte, gibibyte, etc.). The decimal SI prefixes kilo, mega etc., are powers of 10. The power of two equivalents are the binary prefixes kibi, mebi, etc. Accordingly: 1 kB = 1000 bytes = 8000 bits; 1 KiB = 2 10 bytes = 1024 bytes = 8192 bits
