Review Questions Answers
1. The most basic circuitry-level computer language is .
a. machine language
b. Java
c. high-level language
d. C++
Answer: a
, Feedback:
The most basic circuitry-level computer language is machine language. Machine
language, or machine code, is the most basic set of instructions a computer can execute.
Java and C++ are both high-level languages and are the opposite of circuitry-level
computer language.
2. Languages that let you use an easily understood vocabulary of descriptive terms, such as read,
write, or add, are known as languages.
a. procedural
b. high-level
c. machine
d. object-oriented
Answer: b
Feedback:
High-level languages use English-like terms; Java is an example of a high-level language.
Procedural languages are those that run by executing a series of procedures or
methods. Machine-level languages do not use English-like terms; they use 1s and 0s.
Object-oriented languages are run by declaring and using objects that contain data and
methods.
3. The rules of a programming language constitute its .
a. syntax
b. logic
c. format
d. objects
Answer: a
Feedback:
The rules of a programming language constitute its syntax.
4. A translates high-level language statements into machine code.
a. programmer
b. syntax detector
, c. compiler
d. decipherer
Answer: c
Feedback:
A compiler translates high-level language statements into machine code. A programmer
writes high-level language statements but does not translate them. “Syntax detector”
and “decipherer” are not terms used in programming.
5. Named computer memory locations are called .
a. compilers
b. variables
c. addresses
d. appellations
Answer: b
Feedback:
Named computer memory locations are variables. Compilers translate programming
statements into machine language; they are not memory locations. Addresses are
unnamed computer memory locations. “Appellations” is not a term used in
programming.
6. The individual operations used in a computer program are often grouped into logical units called
.
a. procedures
b. variables
c. constants
d. logistics
Answer: a
Feedback:
The individual operations used in a computer program are often grouped into logical
units called procedures. Variables are named memory locations, and constants are
, values that do not change; they are not groups of logical operations. “Logistics” is not a
term commonly used in programming.
7. Envisioning program components as objects that are similar to concrete objects in the real world
is the hallmark of .
a. command-line operating systems
b. procedural programming
c. object-oriented programming
d. machine languages
Answer: c
Feedback:
Envisioning program components as objects that are similar to concrete objects in the
real world is the hallmark of object-oriented programming.
8. The values of an object’s attributes are known as its .
a. state
b. orientation
c. methods
d. condition
Answer: a
Feedback:
The values of an object’s attributes are known as its state.
9. An instance of a class is a(n) .
a. method
b. procedure
c. object
d. case
Answer: c
