Byte and is also combined with metric prefixes for multiples, for example ko and Mo. The usage of the term "octad(e)" for eight bits is no longer common. Despite standardization efforts, ambiguity still exists in the meanings of the SI (or metric) prefixes used with the unit byte, especially concerning the prefixes "kilo" (k or K), "mega" (M), and "giga" (G). Computer memory has a binary architecture in which multiples are expressed in powers of 2. In some fields of the software and computer hardware industries a binary prefix is used for bytes and bits, while producers of computer storage devices
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
