TEXAS TECH ISQS EXAM 1 – DELGADILLO STUDY GUIDE, PRACTICE TEST & EXAM
REVIEW 2026/2027
Data - ✔✔Raw facts
Information - ✔✔The meaningful interpretation of data that enables us to make decisions.
What makes data = information? - ✔✔It's usefulness!
Characteristics of good information - ✔✔Accurate, complete, economical, flexible, reliable, relevant,
simple, timely, verifiable.
System - ✔✔An organized collection of interrelated parts that work together to achieve a common
purpose.
What do systems have? - ✔✔Inputs,
procession mechanism,
outputs,
feedback,
control.
Subsystem - ✔✔(Of a system) University -> Business school -> Marketing.
Simple vs. Complex System - ✔✔Simple- Very few elements & components, relationship is simple.
Complex- A system filled with many simple systems.
A collection of simple systems is better than one, large complex system.
Open vs. Closed System - ✔✔Open- Everyone can use, don't have to have control of market (interact
with other systems)
Closed- Exclusive, not adoptable; only if you have control of market (no interaction)
Information Technology - ✔✔Refers to the method, techniques and tools that are used as means to
bring about computer-based information systems.
Information System - ✔✔Is a set of interrelated components
that collect (input), manipulate and
store (processing), and disseminate
(output) data and information as well
as a feedback mechanism.
What is input and processing? - ✔✔Input - is the activity of capturing
and gathering raw data.
, Processing - involves converting or
transforming raw data into useful
output.
Output - ✔✔Involves producing useful
information, usually in the form of
documents and reports.
Feedback - ✔✔Is output that is used to make
adjustments or changes to input or
processing activities.
Control - ✔✔Involves monitoring and
evaluating feedback.
Computer Based Information System - ✔✔is an Information System that uses computer systems,
devices, and technology.
Computer-Based IS Components?! - ✔✔Hardware, Database, Networks, Procedures
***Software, People = KEY!!!!***
Comparative Advantage - ✔✔Is a significant and long-term benefit to a
company in relation to the competition (innovative thinking, IDEAS!!)
Competing with Information
Technology - ✔✔Competitive value of IT lies mostly in the
capability of software and of people and the
value of information a business acquires and
uses.
Strategic Information Systems - ✔✔Any kind of IS that uses IT to gain competitive advantage (or
sometimes reduce competitive advantage).
Major types of IS - ✔✔- DSS - decisions (what if analysis) - Strategic, Upper
- MIS - reporting - Tactical, Middle
- TPS - transactions - Operational, Lower
Transaction Processing System - ✔✔Is an organized collection of people,
procedures, databases, and devices (software) used to develop and distribute business transactions.
Management Information System - ✔✔Is an organized collection of people, procedures, databases, and
devices, used to provide routine information to decision makers. (**Reports)
Decision Support System - ✔✔Is an organized collection of people, procedures, databases, and devices
used to support problem-specific decision making.
Expert System - ✔✔Is an organized collection of people, procedures, databases, and devices used to
generate expert advise or suggest a decision in an area (become more accurate).
