Explain the difference between application software and system software.
Application softwares enables users to complete a particular application or task, such as word processing, investment analysis, data manipulation, or project management.
System software enables applications to run on a computer. It also manages the interaction between the CPU, memory, storage, input/output devices, and other computer components.
2
Enumerate the different generations of programming languages and explain how they differ
a) First Generation - Machine language: It is the only language that computer hardware understands. It need to create long strings of 0s and 1s.
b) Second Generation - Assembly language: made programming somewhat easier because they aggregated common commands into “words”, although many of the “words” are not English-like.
c) Third-generation languages (3GLs) - known as “procedural” languages as programmer must detail logical procedure.One 3GL statement = 5 to 10 assembly language statements.
d) Fourth-generation languages (4GLs) - more English-like than commands in 3GL procedural languages. Speed up the development process. They are built around database management systems. One 4GL statement = several 3GL statements.

a) Ease of learning the language
b) Ease of programming
c) Significantly shorter code
d) Ease of debugging
e) Ease of maintenance
Disadvantages:

Explain the types and uses of Website design tools
Website design tools are used to develop and change the content of webpages

Clarify the differences between proprietary software and open source software
Proprietary software:
a) Sold/licensed for profit
b) Source code is private and not available
c) Developer retains all rights to the software; user purchases a license to use the software
Open source software:
a) Free source code
b) Developed through voluntary collaboration of programmers
c) Reviewed by many programmers hence, there are fewer bugs
d) Eg. Mozilla Firefox, MySQL, Linux
6
What are the advantages of open source software over proprietary software?
Advantages:
a) It has fewer bugs because thousands of independent programmers review the code
b) It can offer more innovative features by incorporating ideas from a diverse set of experts from different countries and cultures who collaborate
c) Free for all to
However, one major disadvantage:
a) Development and support depend on the continued effort of an army of volunteers
7

b) Fitness for purpose
c) Ease of learning to use
d) Ease of use
