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 One-to-one computing In the context of education, one-to-one computing (sometimes abbreviated as "1:1") refers to academic institutions, such as schools or colleges, that allow each enrolled student to use an electronic device in order to access the Internet, digital course materials, and digital textbooks. The concept has been actively explored and sporadically implemented since the late 1990s. One-to-one computing used to be contrasted with a policy of "bring your own device" (BYOD), which encourages or requires students to use their own laptops, smartphones or other electronic devices in class. The distinction between BYOD and school-issued devices became blurred when many
