1. The most basic circuitry-level computer language is ____________.
R
Prim
a. machine language
b. Java
SE
c. high-level language
d. C++
edo
Answer: a
Feedback:
D
The most basic circuitry-level computer language is machine language. Machine language, or machine
cs
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
Prim
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
edo
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.

The rules of a programming language constitute its syntax.
4. A ____________ translates high-level language statements into machine code.
U
a. programmer
b. syntax detector
R
Prim
c. compiler
d. decipherer
SE
Answer: c
Feedback:
edo
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.
D
5. Named computer memory locations are called ____________.
cs
a. compilers
O
b. variables
c. addresses
C
d. appellations
Answer: b
Feedback:
S
Named computer memory locations are variables. Compilers translate programming statements into
Prim
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
____________.

c. constants
edo
d. logistics
Answer: a
Feedback:
cs
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.

edo
Answer: a
Feedback:
D
You must compile classes written in Java into bytecode. Source code is the high-level programming
cs
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.
