Review Questions Answers
1. The most basic circuitry-level computer language is ____________.
R
a. machine language
b. Java
SE
c. high-level language
d. C++
Answer: a
Feedback:
D
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.
O
2. Languages that let you use an easily understood vocabulary of descriptive terms, such as read, write, or add, are
known as ____________languages.
C
a. procedural
b. high-level
S
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.

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

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.

Answer: a
Feedback:

You must compile classes written in Java into bytecode. Source code is the high-level programming
statements. Javadoc statements are a type of comment used for documentation. Object code is the low-
level code produced when a compiler translates high-level code.
