Though a program is typically still flawed at this stage, it should be relatively functional. Binary file - A file in which information is expressed entirely as combinations of ones and zeros. Executable program files are stored in binary format. Bit - The smallest unit of stored information on a computer. A bit can have a value of zero or one.
More meaningful information is obtained by combining consecutive bits into larger units.
For example, a byte is composed of 8 consecutive bits. Bitmap image - A graphics file format in which every bit represents a pixel on a monitor or a dot on a page. Bitmapped files generally have the file extension .BMP, .PCX, . Bookmark - A tool used by browsers that allow the user to save the URL of a Web page and easily refer to it at another time. Boolean - A branch of mathematics, established by George Boole, that deals with logical expressions.
