[#456] Time during which a job is processed by the computer is
Correct Answer

(C) Execution time

Explanation

Solution: In computer science, run time, runtime or execution time is the time during which a program is running (executing), in contrast to other program lifecycle phases such as compile time, link time and load time.

[#457] Which of the following is used to insure the high quality of computer output?
Correct Answer

(B) output controls

Explanation

Solution: Output controls used to insure the high quality of computer output. Output controls ensure that computer programs process these transactions accurately and produce the results we expect to see.

[#458] The most common binary code in use today is the 8 bit ASCII code. What do the letters ASCII stand for?
Correct Answer

(B) American Standard Code for Information Interchange

Explanation

Solution: ASCII to Extended ASCII characters (8-bit system) and ANSI Code: In the 1960s, a need for standardization led to ASCII, which is a 7-bit system. But later almost everything was done in an 8-bit system. With 7 bits, 128 numbers (0-127 in decimal notation) are available to code characters. A bit is a binary digit which can have either two values, on or off. Seven bits can have 2^7 or 128 possible unique values. ASCII was soon expanded to an 8-bit system that has 256 code points, 0-255 (8-bit corresponds to 2 ^ 8 ie. 256 possibilities). There are many variants of Extended ASCII characters (8-bit system) to cover regional characters and symbols. One example is the extended ASCII characters which includes various letters needed for writing languages of Western Europe and certain special characters. Source : wikipedia.org

[#459] The software used to convert source program instructions to object instruction is known as
Correct Answer

(D) Language processor

Explanation

Solution: A language processor is a software program designed or used to perform tasks, such as processing program code to machine code. Language processors are found in languages such as Fortran and COBOL.

[#460] Binary numbers need more places for counting because:
Correct Answer

(D) Binary base is small

Explanation

Solution: Binary number. In mathematics and digital electronics, a binary number is a number expressed in the base-2 numeral system or binary numeral system, which uses only two symbols: typically 0 (zero) and 1 (one) and two. They also call it base-2. The base-2 numeral system is a positional notation with a radix of 2.
