Binary-coded decimal Binary-coded decimal In computing and electronic systems, binary-coded decimal (BCD) is a class of binary encodings of decimal numbers where each decimal digit is represented by a fixed number of bits, usually four or eight. Special bit patterns are sometimes used for a sign or for other indications (e.g., error or overflow). In byte-oriented systems (i.e. most modern computers), the term "unpacked" BCD usually implies a full byte for each digit (often including a sign), whereas "packed" BCD typically encodes two decimal digits within a single byte by taking advantage of the fact that four bits are enough to represent
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
