devices the techniques were tailored to gate networks of the type described above. The term gate was already in use in the forties to denote the logical elements discussed earlier. There are very many good references on Boolean algebra and we may quote only a selected few of them. Suffice it to mention the texts by Hill and Peterson [1974], Kohavi [1978], and Hohn [1966]. These books give

The true language of computers is a stream of 1s and 0s—bits. Everything in the computer, be it numbers or text or program, spreadsheet or database or 3-D rendering, is nothing but an array of bits. The meaning of the bits is in the “eye of the beholder”; it is determined entirely by context. Bits are not a useful medium for human consumption. Instead, we insist that what we read be formatted spatially and presented

Input devices are those portions of computer, data processing, and information systems that perform the essential function of providing some means for entering commands and data into the system. Therefore, input devices are found in all such systems, but are treated here as a separate equipment group, independent of the

The term computer graphics refers to the generation,representation, manipulation, processing, and display of data by a computer. Computer-generated images may be real or imagined, animated or still, two-dimensional (2-D) or three-dimensional (3-D).Today most computers, particularly those in the PC,Macintosh, or workstation categories
