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
Social computing social aspects into technological and corporate domains. Companies and industries such as Google, Cisco and Fox have invested in such endeavors. Possible questions to be answered through social computing research include how to form stable communities, how these communities evolve, how knowledge is created and processed, how people are motivated to participate, etc. Currently, research in the areas of social computing is being done by many well known labs owned by Microsoft and Massachusetts Institute of Technology. The team at Microsoft has taken off with a mission statement of "To research and develop software that contributes to compelling and effective
