Byte codified this common meaning. Many types of applications use information representable in eight or fewer bits and processor designers optimize for this common usage. The popularity of major commercial computing architectures has aided in the ubiquitous acceptance of the eight-bit size. Modern architectures typically use 32- or 64-bit words, built of four or eight bytes. The unit symbol for the byte was designated as the upper-case letter "B" by the International Electrotechnical Commission (IEC) and Institute of Electrical and Electronics Engineers (IEEE) in contrast to the bit, whose IEEE symbol is a lower-case "b". Internationally, the unit "octet", symbol "o",
One-to-one computing these reasons, one-to-one computing is a major part of education policy in many countries. These benefits also underlie the one-to-one model of One Laptop per Child (OLPC), a charity that aims to issue electronic devices to millions of children in the developing world. With the growth of the internet-connectivity the possibility to use cloud-computing to transfer the data and administration from the devices to cloud-computing has removed the necessity of much of the tech support from the teacher. The ultimate academic benefits of one-to-one, if any, are unclear. They may not be the same for the different eras of 1:1.
