Microcom Networking Protocol problem, additional "framing" bits are added to either end of every byte, typically one bit on either side known as the "start and stop bits". This guarantees at least one 1-to-0 transition for every byte, more than enough to keep the clocks locked. However, these bits also expand every 8 bits of data (one byte) to 10 bits, an overhead of 20%. When using a file transfer protocol, the packets themselves offer their own framing. The packets will always send a continuous stream of data, so the clock cannot "drift" in the same way that it could for data being
One-to-one computing their general brand-related image and comparative ease of use compared to Laptops/Desktops. The Chromebook era had several major success-factors (several of which were often also used in iPad 1:1 schools). Because 1:1 computing programs may have many goals, from improving educational outcomes to increasing equality, and are associated with such a wide range of teaching methods, it is also difficult to judge their overall success or value. One notable benefit that has been documented and researched is the potential for 1:1 computing initiatives to support the use of open educational resources (OER), available in digital form, for ubiquitous access by
