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

Computer networks are geographically distributed collections of communication links and switching proces￾sors, the purpose of which is to transport data between computers, workstations, and terminals. In general the elements of a computer network must follow compatible rules of operation together to function effectively. These rules of operation are known as protocols

The last decade has seen a revolution in software engineering tools and techniques. This revolution has been fueled by the ever-increasing complexity of the software component of delivered systems. Although the software component of delivered systems may not be the most expensive component, it is usually, however, “in series” with the hardware component; if the software doesn’t work, the hardware is useless

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
