64-bit computing 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 address, with the remaining
Creative Computing (magazine) Creative Computing (magazine) Creative Computing was one of the earliest magazines covering the microcomputer revolution. Published from October 1974 until October 1985, the magazine covered the whole spectrum of hobbyist/home/personal computing in a more accessible format than the rather technically oriented "BYTE". "Creative Computing" also published software on cassette tape and floppy disk for the popular computer systems of the time. The magazine was founded by David H. Ahl, who sold it to Ziff-Davis in the early 1980s, but remained as editor-in-chief. Featured writers included Robert Swirsky, David Lubar, and John J. Anderson. The magazine regularly included BASIC source code
