Character (computing) of the “basic execution character set” and (in newer C standards) UTF-8 code units which implies a minimum size of 8 bits. The exact number of bits can be checked via codice_2 macro. By far the most common size is 8 bits, and the POSIX standard "requires" it to be 8 bits. Since Unicode requires at least 21 bits to store a single code point, it is usually impossible to store one inside a single codice_1; instead a variable-length encoding such as UTF-8 must be used. Unfortunately, the fact that a character was historically stored in a single byte led
Byte (magazine) C, BASIC, assemblers), and coverage of the first microcomputer operating system, CP/M. "Byte" ran Microsoft's first advertisement, as "Micro-Soft", to sell a BASIC interpreter for 8080-based computers. In spring of 1979, owner/publisher Virginia Williamson sold "Byte" to McGraw-Hill. She remained publisher until 1983 and became a vice president of McGraw-Hill Publications Company. Shortly after the IBM PC was introduced, in 1981, the magazine changed editorial policies. It gradually de-emphasized the do-it-yourself electronics and software articles, and began running product reviews. It continued its wide-ranging coverage of hardware and software, but now it reported "what it does" and "how it works",
