WGU C173 - Scripting and Programming
Foundations: Questions With A+ Solutions
Instruction types Correct Answer - input, process, output
Input Correct Answer - A program gets data, perhaps from a
file, keyboard, touchscreen, network, etc.
Process Correct Answer - A program performs computations
on that data, such as adding two values like x + y.
Output Correct Answer - A program puts that data somewhere,
such as to a file, screen, network, etc.
Computational thinking Correct Answer - creating a sequence
of instructions to solve a problem
Flowchart Correct Answer - A diagram that shows step-by-
step progression through a procedure or system especially using
connecting lines and a set of conventional symbols.
Program Correct Answer - a list of statements or actions to
accomplish a task in a computer program
Interpreter Correct Answer - Converts a program written in a
higher level language into a lower level language and executes it,
beginning execution before converting the entire program.
Run and execute Correct Answer - What are words for
carrying out a program's statements?
Variable Correct Answer - A name that can hold a value
, String literal Correct Answer - text in double quotes
Character Correct Answer -
Newline Correct Answer - A special two-character sequence
whose appearance in an output string literal causes the cursor to
move to the next output line.
Put item to output Correct Answer - How is an output
statement written?
Variable = get next input Correct Answer - How is an input
statement written?
Comment Correct Answer - text a programmer adds to a
program -- is understood by humans to better understand the code,
but is ignored by the program when executing.
Whitespace Correct Answer - refers to black spaces between
items within a statement, and to newlines. Helps improve
readability for humans.
Moore's Law Correct Answer - the observation that computing
power roughly doubles every two years.
Embedded computer Correct Answer - a computer inside
another electrical device, like inside a TV, car, printer, thermostat,
etc
Bit Correct Answer - binary digit
ASCII Correct Answer - a code for representing English
characters as numbers, with each letter assigned a number from 0 to
127
