[#876] A large computer designed to handle complex scientific calculations
Correct Answer

(A) may use only a firmed word-length storage approach

Explanation

Solution: A large computer designed to handle complex scientific calculations may use only a firmed word-length storage approach. It is used for scientific and engineering applications that must handle very large databases or do a great amount of computation.

[#877] The 7-bit ASCII code widely used
Correct Answer

(A) For data communication work

Explanation

Solution: ASCII, abbreviation of American Standard Code For Information Interchange, a standard data-transmission code that is used by smaller and less-powerful computers to represent both textual data and no input-device commands (control characters).

[#878] A technique for processing jobs on a first-come, first-served basis is known as
Correct Answer

(B) FIFO

[#879] A device mounted on a communication satellite which receives, amplifies and re-transmits signals from earth station is
Correct Answer

(B) Transponder

Explanation

Solution: A device mounted on a communication satellite which receives, amplifies and re-transmits signals from earth station is transponder. A transponder is typically composed of: an input band-limiting device (an input band-pass filter), an input low-noise amplifier (LNA), designed to amplify the signals received from the Earth station.

[#880] Which of the following languages is often translated to pseudo code?
Correct Answer

(C) PASCAL

Explanation

Solution: Pseudo code is commonly used to teach algorithms for computer science students in an introductory programming course. When an automatic translation tool is available, students can translate their pseudo code to source code and then execute the resulted source code to check whether their algorithm is correct.
