REVIEW QUESTIONS ANSWERS
1. Computer programs also are known as _______________. (1.1)
a. data
b. hardware
c. software
d. information
Answer: c
Feedback:
a. Incorrect. Data is the facts and figures that are input to programs.
b. Incorrect. Hardware is computer equipment.
c. Correct. Computer programs are called software as opposed to computer
equipment, which is hardware. Data is the facts and figures that are input into
programs, while information is data that has been processed and output.
d. Incorrect. Information is data that has been processed and output.
2. The major operations performed by all sizes of computers include _______________.
(1.1)
a. input, processing, and output
b. hardware and software
c. sequence and looping
d. spreadsheets and word processing
Answer: a
Feedback:
1
, a. Correct. All computers perform input, processing, and output to change data
into information. Hardware and software are, respectively, the equipment and
programs in a computer system. Sequence and looping describe groups of
software instructions, and spreadsheets and word processing are examples of
software applications.
b. Incorrect. Hardware and software are equipment and programs, respectively.
c. Incorrect. Sequence and looping are two logical structures.
d. Incorrect. Spreadsheets and word processing are examples of software
applications.
3. Visual Basic, C++, and Java are all examples of computer _______________. (1.1–1.3)
a. operating systems
b. programming languages
c. hardware
d. machine languages
Answer: b
Feedback:
a. Incorrect. Operating systems manage computer resources. Windows, Linux,
Apple iOS, and Unix are examples of operating systems.
b. Correct. Visual Basic, C++, and Java are high-level programming languages.
They are far more English-like than machine language, which consists of 0s and
1s. Hardware is equipment. Operating systems are the software that manage a
computer’s resources.
c. Incorrect. Hardware is equipment such as printers and monitors.
d. Incorrect. Machine languages are binary language; Visual Basic, C++, and Java
are higher-level languages, meaning they are more English-like.
4. A programming language’s rules are its _______________. (1.1)
a. syntax
b. logic
c. format
d. options
Answer: a
Feedback:
a. Correct. A programming language’s rules are its syntax.
b. Incorrect. Logic is the series of events that leads to a solution.
c. Incorrect. The term “format” has nothing to do with language rules.
d. Incorrect. Options are not programming language rules.
5. The most important task of a compiler or interpreter is to _______________. (1.1)
2
, a. create the rules for a programming language
b. translate English statements into a language such as Java
c. translate programming language statements into machine language
d. execute machine language programs to perform useful tasks
Answer: c
Feedback:
a. Incorrect. The designers of a programming language create its rules.
b. Incorrect. Programmers translate English statements into programming
languages.
c. Correct. Compilers and interpreters translate programming language
statements into machine language.
d. Incorrect. A computer’s CPU executes programs.
6. Which of the following is temporary, internal storage? (1.1)
a. CPU
b. hard disk
c. keyboard
d. memory
Answer: d
Feedback:
a. Incorrect. A CPU is hardware that performs processing.
b. Incorrect. A hard disk is a hardware storage device.
c. Incorrect. A keyboard is a hardware input device.
d. Correct. Memory is temporary, internal storage.
7. Which of the following pairs of steps in the programming process is in the correct
order? (1.3)
a. code the program, plan the logic
b. test the program, translate it into machine language
c. put the program into production, understand the problem
d. code the program, translate it into machine language
Answer: d
Feedback:
a. Incorrect. You must plan the logic before you code the program.
b. Incorrect. You must translate the program into machine language before it can
be tested.
c. Incorrect. You must understand the problem before you can write the program
and ultimately put it into production.
