This article will explain in detail what is the basic unit of data storage, and the content of the article is of high quality, so the editor will share it for you as a reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

The basic unit of computer data storage is bytes.

1. Byte

Bytes are the basic unit of computer data processing. A byte consists of a binary bit, often denoted by B. In computers and other digital devices, bytes are generally used as the basic unit of storage capacity. In addition to B (bytes), there are KB (kilobytes), MB (megabytes), GB (gigabytes), TB (terabytes), PB (petabytes) and so on.

2. Word

In a computer, a string of numbers is processed or operated as a whole, which is called a computer word, abbreviated word (word). A word usually consists of one or more bytes. For example, the word of 286 microcomputer is composed of 2 bytes, the word length of 16x 486 microcomputer is composed of 4 bytes, and its word length is 32 bits.

Extended data

Binary abbreviations of data storage expression units, full name pronunciation in Chinese and English, abbreviations and byte pronunciation:

1. Bit/bit/ n. [C] bit, which describes the smallest unit of computer data, the Chinese name "bit" transliterates "bit", abbreviation b (fixed lowercase), proposed by mathematical statistician John Tuckey (JohnWilderTukey) in 1946 (some data said it was proposed in 1943), from binarydigit (binary number), each 0 or 1 in the binary number system is a bit (bit).

The term was first formally used in C.E. Shannon's famous paper, Mathematical Theory of Communication (AMathematicalTheoryofCommunication), p. 1.

2. Byte/bait/n. [C] bytes, abbreviated B (commonly capitalized), invented by IBM computer designer Werner Buckholtz (WemerBuchholz) in 1956, created by bite (bite) but respelled as byte to avoid bit.

A byte can encode 256 different values (2 ^ 8, that is, all different combinations of 8 zeros and ones), which can be an integer between 0 and 255, or a letter or symbol in the ASCII character set. The English alphabet encoded by ASCII/ANSI occupies one byte and the Chinese character occupies two bytes.

3. Kilo/ "ki:l questions" / n. From the Greek χ "λ" thousand; acronym K thousand; [thousand], 1p 0001 or 10 ^ 3 or 1 × 103kg unit of quantity; kilobyte kilobit (kb), kilobyte KiloByte (KB=Kilobyte kilobyte), abbreviated as k/K/ kilobyte

4. Mega/ meg / n. From the Greek μ "γ α", (megas) means "million" million; abbreviation M [megabyte], 1m megabyte MegaByte (MB= megabyte megabyte / megabyte), M / megabyte

5. Giga/'g gigabytes / n. From the Greek γ "γ α" means giant/ "100 million" billion; abbreviation G [Giga] coffee, 1 million or 10 ^ 9 or 1 × 109 gigabyte units / also known as "gigabyte / Beijing"; gigabyte GigaByte (GB=Gigabyte gigabyte / gigabyte), abbreviated as G / Gigabyte

6. Tera/'t terabytes / n. From the Greek τ "p α" means "four" (tetra); abbreviation T [tetra], 1 million or 10 ^ 12 or 1 × 1012 trillion / megabyte unit of quantity / also known as "terabyte"; terabyte TeraByte (TB= Trillionbyte terabytes), abbreviated as T / Tai

7. Peta/ / n. From the Greek π pound tau ε meaning five "five" (penta); abbreviation P [beat] it, 1 million 0005 or 10 ^ 15 or 1 × 1015 trillion units of quantity; petabyte PetaByte (PB= Petabyte kilobytes), abbreviated as P / Pat

8. Exa/'eks billion / n. From the Greek word EB= ξ (h é x) meaning six "six" (hexa); abbreviated Ehrkosa, 1m 0006 or 10 ^ 18 or 1 × 1018 billion level unit of quantity; exabyte ExaByte (EB= Exabyte 10 billion bytes), abbreviated as E / Ai

9. Zetta/'zi million / n. From the Greek "π τ" (hepta) meaning seven "seven"; abbreviated Z [Zeta] it / Zeta, 1 million 10.0001 trillion or 10 ^ 21 or 1 × 1021 10.0001 trillion units of quantity; Zettabyte ZettaByte (ZB=Zettabyte 10.0001 trillion bytes), abbreviated as Z / Zeta

10. Yotta/'j billion / n. It comes from the ancient Greek word "kappa tau" (okt ó) meaning eight "eight"; the acronym Y [Yao] it, 1 million or 10 ^ 24 billion or 1 × 102.4 billion units of quantity; Yao byte YottaByte (YB= Yottabyte billion bytes), abbreviated as Y / Yao.
