発音

名詞

byte (plural bytes)

(computing) A short sequence of bits (binary digits) that can be operated on as a unit by a computer; the smallest usable machine word.
(computing, most commonly) A unit of computing storage equal to eight bits, which can represent any of 256 distinct values.

Synonyms: B, octet

The word “hello” fits into five bytes of ASCII code.
- 1984, Neil Ardley, “The ZX Spectrum+ Memory Map”, Learn About Your ZX Spectrum+ (3), in Sinclair ZX Spectrum+ User Guide, Dorling Kindersley, →ISBN, page 48:
  
  If you look at the photograph of the interior of the Spectrum […], you will see that there is one ROM chip, and 16 smaller RAM chips. These chips give the Spectrum its memory. The memory consists of 65536 storage units that each contain one byte (a number from 0 to 255).
- 2008, Eric Johnson, Joshua Jones, A Developer 's Guide to Data Modeling for SQL Server:
  
  With a varchar, the storage is always the actual number of characters you have stored plus 2 bytes. So a varchar(20) with a 5-character word will take up 7 bytes, with the extra 2 bytes holding a size reference for SQL Server.
