REVIEW QUESTIONS
1. Computer software is divided into two broad categories: system software and
operational software.
a. True
b. False
Answer: b. False
Feedback: Computer software is divided into two categories: system software and
application software.
2. The operating system provides services such as a user interface, file and database
access, and interfaces to communications systems.
a. True
b. False
Answer: a. True
Feedback: Operating system is the interface between the user and the computer
hardware.

4. The programmer design tool used to design the whole program is the flowchart.
a. True
b. False
Answer: b. False
, Feedback: Flowchart is a tool to represent the flow of data through a program and
how it is processed.
