Byte addressing might still need to access 8-bit data over its 64-bit address line, and have the data returned in the bottom 8 bits of its longer data line. Byte addressable memory refers to architectures where data can be accessed and addressed in units that are narrower than the bus. An eight-bit processor like the Intel 8008 addresses eight bits, but as this is the full width of the bus, this is regarded as word-addressable. The 386SX, which addresses memory in 8-bit units but can fetch and store it 16 bits at a time, is termed byte-addressable. Bytes have not always meant
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.
