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
One-to-one computing that 1:1 availability of devices improves their usefulness. Having to share devices reduces their educational efficacy because of the reduced intensity & length of the experience and the additional time spent on file-management, configuration management, device management and distribution. Before cloud-computing the main benefits referred to access to devices. As cloud-computing progressed collaboration, cost reduction, going paperless, 21st century skills became more of a focus. Red research included 1:1 and collaboration in its key research findings. One-to-one computing offers the benefits of equal access, standardization, easy upgrades, simple networking and the ability to monitor student progress and online behavior. For
