Design of the FAT file system significant bits the second (f.e cluster 1). In other words, while the low eight bits of the first cluster in the row are stored in the first byte, the top four bits are stored in the low nibble of the second byte, whereas the low four bits of the subsequent cluster in the row are stored in the high nibble of the second byte and its higher eight bits in the third byte. The FAT16 file system uses 16 bits per FAT entry, thus one entry spans two bytes in little-endian byte order: The FAT32 file system uses 32 bits
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",
