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
Women in computing in Canada 2000, Norway had 23.2% in 1999, and Sweden had 30% in 2000. The United Kingdom was approximately in the middle at 19% in 1999. Women in computing in Canada Canada shares many of the concerns particularly prevalent in the developed and developing world about the current and future roles of women in computing, especially as these occupations increase in importance. As in much of the world where computing and information technology is a large industry, women have historically faced underrepresentation in education and industry. As a result, some Canadian women pursuing careers in these fields have had a lack of
