1

This processes data and transactions to provide users with the information they need to plan, control, and operate an organization

An Information System

2

T/F

Overall, manual accounting systems have been replaced by computerized accounting information systems

TRUE

3

These are designed to improve productivity by supporting daily work of employees (Word, Excel, Email, etc.)

Office Automation Systems

4

This involves the daily processing of transactions (payroll recording, cash receipts, cash disbursements)

Transaction Processing Systems

5

This is designed to help with the decision-making process by providing access to computer data

Management Reporting Systems

6

This is an example of a management reporting system that is designed to provide past, present, and future information for planning, organization, and controlling the operations of the organization

Management Information Systems

7

This is an example of a management reporting system that is computer-based and combines models and data to resolve non-structured problems with extensive user involvement

Decision Support Systems

8

This is an example of a management reporting system that is computer-based and applies reasoning methods to data in a specific relatively structured area to render advice or recommendations

Expert Systems

9

This is an example of a management reporting system is a computerized system that is specifically designed to support executive work

Executive Information Systems

10

What are the phases in a Systems Development Lifecycle (SDLC)

(7 Phases - PADDTIM)

1) Planning
2) Analysis
3) Design
4) Development
5) Testing
6) Implementation
7) Maintenance

11

This is a type of testing under the testing phase (in a systems development lifecycle) that involves testing the pieces of code

Unit Testing

12

This is a type of testing under the testing phase (in a systems development lifecycle) that involves testing of the integration of the units/pieces of code into a system

System Testing

13

This is a type of testing under the testing phase (in a systems development lifecycle) involves testing where the separate systems can work together

Integration Testing

14

This is a type of testing under the testing phase (in a systems development lifecycle) which determines whether the system meets the business requirements and enables users to perform their jobs efficiently and effectively

User Acceptance Testing

15

This is a type of implementation under the implementation phase (in a systems development lifecycle) that uses two systems (old and new) until it is determined that the new system is operating properly

Parallel Implementation

16

This is a type of implementation under the implementation phase (in a systems development lifecycle) that ceases the old system and begins using the new system immediately

Plunge Implementation

17

This is a type of implementation under the implementation phase (in a systems development lifecycle) that involves having a small group of individuals using the new system until it is seen to be working properly

Pilot Implementation

18

This is a type of implementation under the implementation phase (in a systems development lifecycle) that involves installing the system in a series of waves

Phased Implementation

19

The advantage of this implementation is that there is less risk of system disaster

Parallel Implementation

20

The disadvantage of this implementation is the additional work and cost during the implementation period

Parallel Implementation

It is VERY expensive to keep both systems running

21

The advantage of this implementation system is that it isn't very costly

Plunge Implementation

22

The disadvantage of this implementation system is that it has high risk of system disaster

Plunge Implementation

23

The advantage of this implementation system is that it provides a partial operational test of the new system at a lower cost

Pilot Implementation

The costs are much lower than the Parallel Implementation where both systems are being used across the board.

24

In which phase of the SDLC would the activity of identifying the problem(s) that need to be solved most likely occur?

Planning Phase

25

List the 5 types of computers in order of largest/highest power to smallest/lowest power

1) Supercomputers
2) Mainframe Computers
3) Servers
4) Microcomputers (desktops/laptops)
5) Tablets/Smart Phones/PDAs

26

What are 4 categories of hardware?

1) Central Processing Unit (CPU)
2) Secondary Storage
3) Input Devices
4) Output Devices

27

What is the slowest & therefore cheapest form of secondary storage hardware, which is used primarily for archiving purposes

Magnetic Tape

28

What type of secondary storage hardware is similar to a USB drive?

Solid State Drives (SSDs)

29

What type of secondary storage hardware is also known as "Storage as a Service" (SaaS), hosted offsite, and is accessed via the internet?

Cloud-Based Storage

30

What is the most common secondary storage hardware medium used today?

Magnetic Disks (hard drives)
