1.These computer uses the stored-program concept. Memory is used to store both program and data instructions and central processing unit (CPU) gets instructions and/ or data from memory. CPU, decodes the instructions and then sequentially performs them.

Options: restoring the operation whenever there is a disk failure, restoring both application and system software whenever there is disk corruption., restoring the data files whenever there is a system crash, All of the above
Which of the following describes the operation of a positive edge-triggered D-type flip-flop?
Options: If both inputs are HIGH, the output will toggle., The output will follow the input on the leading edge of the clock., When both inputs are LOW, an invalid state exists., The input is toggled into the flip-flop on the leading edge of the clock and is passed to the output on the trailing edge of the clock.
6.Lehmanâ€™s Fourth Law (Lehman and Belady 1985) is
Options: (A)Organizational stability: Over a programâ€™s lifetime, its rate of development is approximately constant and independent of the resources devoted to system development. (B) Increase complexity: As an evolving program change, its strictures tend to become more complex. Extra resources must be devoted to preserving and simplifying the structure. (C) Large program evolution: Program evolution is a self-regulating process. (D) None of these 20
Which of the following is not true of immediate processing?
Options: It is often used in real-time applications, It can occur with either sequential of direct-access files, It can be used in an airline-reservation system, Transactions are processed shortly after a real-world event occurs
Why is the width of the data bus so important to the processing speed of a computer?
Options: The narrower it is, the greater the computer's processing speed, The wider it is, the more data that can fit into main memory, The wider it is, the greater the computer's processing speed, The wider it is, the slower the computer's processing speed
