Sometimes our output is short-term, such as printing a photo, and sometimes what we work on needs to be kept around for a while. That's where storage comes in.
[#923] A printer in which the characters are embossed on a band is
Correct Answer
(D) Chain
Explanation
Solution: Band printers are a variation of chain printers in which a thin steel band is used instead of a chain, with the characters embossed or etched onto the band. Connected in series, one after the other. Transmitted signals go to the first device, then to the second and so on.
[#924] A type of simulation method using random numbers to determine the evolution of a system is
Correct Answer
(B) Monte carlo
Explanation
Solution: 1) A type of simulation method using random numbers to determine the evolution of a system is Monte carlo. 2) Monte Carlo simulation is a computerized mathematical technique that allows people to account for risk in quantitative analysis and decision making.
