[#581] Which of the following is not true of future computers?
Correct Answer
increased use of CAD/CAM techniques
Explanation
Solution: It is the use of computers to interactively design products and prepare engineering documentation. Increased use of CAD/CAM techniques, faster turnaround time, developments in artificial intelligence systems, development of products more suitable for human use.
[#582] The EAM device that does not use a control panel is the:
Correct Answer
(D) sorter
Explanation
Solution: The EAM device that does not use a control panel is the sorter. Electro-absorption modulator (EAM) is a semiconductor device which can be used for modulating the intensity of a laser beam via an electric voltage.
[#583] Whenever a peripheral is being controlled by the CPU, it is said to be online. If additionally, the computer files are updated as soon as any change takes place, the system is called
Correct Answer
(C) real time system
Explanation
Solution: The peripheral is being controlled by the CPU, it is said to be online. If additionally, the computer files are updated as soon as any change takes place, the system is called real time system.
[#584] The following is true about 2-out of-5 code:
Correct Answer
(B) it is unweighted code
Explanation
Solution: A two-out-of-five code is a constant-weight code that provides exactly ten possible combinations of two bits, and is thus used for representing the decimal digits using five bits. Each bit is assigned a weight, such that the set bits sum to the desired value, with an exception for zero.
[#585] The Josephson tunneling device illustrates principles associated with the advanced storage technique:
Correct Answer
(A) cryogenics
Explanation
Solution: Cryogenics is the study of material sciences at extremely low temperatures. Cryogenics is of particular interest when applied to electricity and silicon-based semiconductor processors because supercooling can be used to bring about superconductivity.
