Byte using six-bit and nine-bit bytes were common into the 1960s. These machines most commonly had memory words of 12, 24, 36, 48 or 60 bits, corresponding to two, four, six, eight or 10 six-bit bytes. In this era, bytes in the instruction stream were often referred to as "syllables", before the term byte became common. The modern "de-facto" standard of eight bits, as documented in ISO/IEC 2382-1:1993, is a convenient power of two permitting the values 0 through 255 for one byte (2 in power of 8 = 256, where zero signifies number as well). The international standard IEC 80000-13
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.
