Options: It is expensive relative to magnetic tape, It provides only sequential access to stored data, Users can easily update records by writing over the old data, It does not provide an automatic audit trail
What is the main advantage of using MOSFET rather than bipolar transistor circuitary in ICs?
Options: much greater complexity (more components) than bipolar circuits : better economy, higher operating speed than bipolar circuits, fewer power supply connections are required with MOS ICs, system designers are more familiar with MOS circuitary
Options: (A)Extent to which a software module can be used in more than one computing program (B) It involves regular monitoring of the risks identified and of new risks that develops. (C) It considers each of the key risks that are identified and identifies strategies to manage the risk. (D) None of these 22
The fan-out capability of a digital building block can be defined as
Options: the number of inputs that one output can transmit to, the amount of cooling required for fanning the hear out, the number of inputs that can transmit to one input, the maximum power dissipation (heat generation) that the unit can stand.
