64-bit computing more generally "multi-arch support". 64-bit computing In computer architecture, 64-bit computing is the use of processors that have datapath widths, integer size, and memory address widths of 64 bits (eight octets). Also, 64-bit computer architectures for central processing units (CPUs) and arithmetic logic units (ALUs) are those that are based on processor registers, address buses, or data buses of that size. From the software perspective, 64-bit computing means the use of code with 64-bit virtual memory addresses. However, not all 64-bit instruction sets support full 64-bit virtual memory addresses; x86-64 and ARMv8, for example, support only 48 bits of virtual
Byte (magazine) not "how to do it". The editorial focus remained on home and personal computers). By the early 1980s "Byte" had become an "elite" magazine, seen as a peer of "Rolling Stone" and "Playboy", and others such as David Bunnell of "PC Magazine" aspired to emulate its reputation and success. It was the only computer publication on the 1981 Folio 400 list of largest magazines. "Byte"s 1982 average number of pages was 543, and the number of paid advertising pages grew by more than 1,000 while most magazines' amount of advertising did not change. Its circulation of 420,000 was the third
