Question 1

Reliance on software - responsibility of (industry) accurately

Answer 1

The software development industry has a responsibility to ensure all systems are reliable and perform their various functions accurately

Question 2

Intellectual property

Answer 2

Property resulting from the fruits of mental labour

Question 3

Acknowledging the intellectual property of others (right)

Answer 3

All people and companies involved in the original creation of the software package are authors and have intellectual property rights in regard to their particular original contribution.

Question 4

Recognition by others of the developer’s Intellectual property

Answer 4

Publishers of software products have a responsibility to ensure the intellectual property rights of all authors involved in the creation of the final product are acknowledged and compensated

Question 5

Producing quality software solutions

Answer 5

The final quality of a software development project is an important responsibility for all software developers.

Question 6

External factors affecting quality - hardware responsibility

Answer 6

The operating system creators have a responsibility to ensure that specifications are published and accurate and that the operating systems perform correctly

Question 7

Neither generating nor transmitting malware

Answer 7

Software developers have a responsibility
to ensure their products do not contain malware. To make sure this is the case they should check any new data and software being added to their computers for viruses

Question 8

Inclusivity responsibility

Answer 8

Software developers have a responsibility that software is accessible to all people regardless of their culture, economics, gender or disability

Question 9

Factors to consider to ensure inclusivity (RECGD)

Answer 9

• Religion
• Economics
• Cultural background
• Gender
• Disability

Question 10

Commercial software (x5)

Copyright, copying, modifications, RE, package

Answer 10

• Covered by copyright
• One archival copy may be made for use only if the original fails
• Modifications to the software are not permitted
• Reverse engineering and decompilation are not permitted
• Use of the work as part of another package is not allowed without permission

Question 11

Shareware (x5)

Copyright, copying, modifications, RE, package

Answer 11

• Covered by copyright
• Copies can be made for archival or distribution purposes
• Modifications to the software are not permitted
• Reverse engineering and decompilation are not allowed
• Use of the work as part of another package is→not allowed without permission

Question 12

Public domain (x5)

Copyright, copying, modifications, RE, package

Answer 12

• Copyright has been relinquished
• Copies can be made with no restrictions
• Modifications to the software are allowable
• Decompilation is allowed
• Developing new works based on the product is allowed without restriction

Question 13

Open source (x5) (CASFE)

Code, copying, distribution, modifications, examples

Answer 13

• Code is developed collaboratively; this encourages collaboration and sharing of ideas without fear of legal challenge
• Available to everyone to modify and redistribute, but modified products must be released using the same unrestricted open source license
• Software distributed under an open source license can be installed and used without restriction
• Freedom to use, change, and share changes of the software
• Examples include Linux OS, the MySQL database management system, Apache web server, 
and programming languages such as Java, PHP and Perl

Question 14

Decompilations

Answer 14

Decompilation

Translating machine executable code into a higher-level code (usually assembler).

Question 15

Structured approach characteristics (x3)

Answer 15

• There is a distinct start and finish
• Characterised by distinct formal stages
• Generally used for large-scale projects where performance and reliability are vital requirements

Question 16

Agile approach characteristics (x2)

Answer 16

• Responds well to changing specifications; specifications are encouraged to change and evolve
• Basic functionality is included initially so operational software can be released as soon as possible

Question 17

Evolutionary & concept prototypes

Answer 17

Evolutionary - used to assist in the formulation of requirements

Concept prototypes - produced to assist in the determination of requirements, they are then discarded 


Question 18

RAD characteristics (x3)

Answer 18

• Creates a usable software solution in the shortest time possible at the lowest possible cost to the client
• Lacks formal stages
• Uses existing modules

Question 19

End user characteristics (x3)

Answer 19

• They usually have little to no experience in programming or software development
• Use of standard software packages

Question 20

CASE tools def

Answer 20

Tools used to assist and coordinate the activities involved in the process of software development

Question 21

CASE tools examples (x3)

Answer 21

• Simple drawing programs
• Text processors
• Analysis tools

Question 22

Direct cut over

Answer 22

Involves the old system being completely dropped and the new system being completely installed at the same time

Question 23

Parallel

Answer 23

Involves operating both systems together for a period. This allows any major problems with the new system to be encountered and corrected without the loss of data

Question 24

Phased

Answer 24

Involves a gradual introduction of the new system whilst the old system is progressively discarded. This can be achieved by introducing new parts of the new product one at a time while the older parts being replaced are removed

Question 25

Pilot (x2)

Answer 25

• The new system is installed for a small number of users . These users learn, use and evaluate the new system
• Once the new system is deemed to be performing satisfactorily then the system is installed for a small number of users
