What is the basic unit of data storage?

#The basic unit of computer data storage is bytes.

1. Bytes

Bytes are the basic unit of computer data processing. 1 byte is composed of binary bits, often represented by B. In computers and other digital devices, bytes are generally used as the basic unit of storage capacity. In addition to B (byte), there are KB (kilobyte), MB (megabyte), GB (gigabyte), TB (terabyte), PB (petabyte), etc.

2. Word

In a computer, a string of numbers is processed or calculated as a whole, which is called a computer word, or word for short. A word usually consists of one or more bytes. For example, the word of the 286 microcomputer consists of 2 bytes, and its word length is 16; the word of the 486 microcomputer consists of 4 bytes, and its word length is 32 bits.

Extended information

The hexadecimal abbreviation of the data storage expression unit, the Chinese and English full name pronunciation, abbreviation and characters Stanza pronunciation:

1, bit/bit/n.[C] bit (bit), the smallest unit that describes the amount of computer data, the Chinese name "bit" is transliterated as "bit", the abbreviation b ( Fixed lowercase), proposed by mathematical statistician John Wilder Tukey in 1946 (some data say it was proposed in 1943), from binarydigit (binary number), each 0 or 1 in the binary number system is a bit (bit).

The first time this term was officially used was on page 1 of C.E. Shannon's famous paper "A Mathematical Theory of Communication".

2. byte/bait/n.[C] Byte, abbreviated B (common capital), was invented by IBM computer designer Wemer Buchholz in 1956 and was developed by bite (bite) Created but respelled as byte to avoid bit.

One byte can encode 256 different values ​​(2^8, that is, all different combinations of 8 0s and 1s). This value can be an integer between 0 and 255, or it can be an ASCII character. Concentrated one letter or symbol. ASCII/ANSI encoded English letters occupy one byte, and Chinese characters occupy two bytes.

3, kilo/ˈki:ləʊ/n. Comes from the Greek χίλιοι (chilioi) meaning "thousand" thousands; abbreviation K/k [thousand], 1,0001 or 10^3 or 1×103 thousand level Unit of quantity; kilobit (kb), kilobyte KiloByte (KB=Kilobyte kilobyte), referred to as k/K/thousand;

4, mega/ˈmegə/n. From the Greek μέγας, ( megas) means "million" million; abbreviation M [mega], 1,0002 or 10^6 or 1×106 million-level quantity unit/also known as "mega"; megabyte MegaByte (MB=Megabyte megabyte / million bytes), abbreviated as M/mega;

5, giga/'gɪgə/n. From the Greek γίγας meaning giant/"billion"; abbreviated as G[吉]卡, 1,0003 Or 10 ^ 9 or 1 ##6, tera/'tɪərə/n. From the Greek τέρας, meaning "four" (tetra); abbreviation T [tera], 1,0004 or 10^12 or 1×1012 trillion/tera level quantity unit / Also known as "哓"; terabyte TeraByte (TB=Trillionbyte trillion bytes), referred to as T/太;

7, peta/ˈpɛtə/n. From the Greek πέντε meaning five "five" ( penta); abbreviation P [beat] it, 1,0005 or 10^15 or 1×1015 quadrillion-level quantitative unit; petabyte PetaByte (PB=Petabyte quadrillion bytes), abbreviation P/beat;

8, exa/'eksə/n. From the Greek ἕξ(héx) meaning six "six" (hexa); abbreviation E[爱]khasa, 1,0006 or 10^18 or 1×1018 tens of billions Unit of quantity in the billions; exabyte ExaByte (EB=Exabyte tens of billions of bytes), referred to as E/Ai;

9, zetta/'ziːtə/n. From the Greek ἑπτά (hepta) meaning seven" "Seven"; abbreviation Z [ze] it/zeta, 1,0007 or 10^21 or 1×1021 ten trillion level quantity unit; ZettaByte ZettaByte (ZB=Zettabyte ten trillion bytes), referred to as Z / Ze;

10, yotta/'jɒtə/n. From ancient Greek οκτώ (októ) meaning eight "eight"; abbreviation Y[尧] it, 1,0008 or 10^24 or 1×1024 A quintillion-level unit of quantity; YottaByte (YB=Yottabyte quintillion bytes), referred to as Y/Yao.
