Unit 6: Computer Software

was part of its Windows operating system or a separable piece of application software. As another
example, the GNU/Linux naming controversy is, in part, due to disagreement about the relationship Notes
between the Linux kernel and the operating systems built over this kernel. In some types of embedded
systems, the application software and the operating system software may be indistinguishable to
the user, as in the case of software used to control a VCR, DVD player or microwave oven. The
above definitions may exclude some applications that may exist on some computers in large
organizations. For an alternative definition of an app: see Application Portfolio Management.

Explain the difference between system and application software with example.

6.3 Application Software Classification

Application software falls into two general categories; horizontal applications and vertical
applications. Horizontal applications are the most popular and widespread in departments or
companies. Vertical applications are niche products, designed for a particular type of business or
division in a company.
There are Many Types of Application Software:
An application suite consists of multiple applications bundled together. They usually have related
functions, features and user interfaces, and may be able to interact with each other, e.g. open each
other’s files. Business applications often come in suites, e.g. Microsoft Office, OpenOffice.org and
iWork, which bundle together a word processor, a spreadsheet, etc.; but suites exist for other
purposes, e.g. graphics or music.
Enterprise software addresses the needs of organization processes and data flow, often in a large
distributed environment. (Examples include financial systems, customer relationship management
(CRM) systems and supply-chain management software). Note that Departmental Software is a
sub-type of enterprise software with a focus on smaller organizations or groups within a large
organization. Examples include travel expense management and IT Helpdesk)
Enterprise infrastructure software provides common capabilities needed to support enterprise
software systems. (Examples include databases, email servers, and systems for managing networks
and security.)
Information worker software addresses the needs of individuals to create and manage information,
often for individual projects within a department, in contrast to enterprise management. Examples
include time management, resource management, documentation tools, analytical, and collaborative.
Word processors, spreadsheets, email and blog clients, personal information system, and individual
media editors may aid in multiple information worker tasks.
Content access software is software used primarily to access content without editing, but may include
software that allows for content editing. Such software addresses the needs of individuals and groups
to consume digital entertainment and published digital content. (Examples include Media Players,
Web Browsers, Help browsers and Games)
Educational software is related to content access software, but has the content and/or features
adapted for use in by educators or students. For example, it may deliver evaluations (tests), track
progress through material, or include collaborative capabilities.

Simulation software are computer software for simulation of physical or abstract systems
for either research, training or entertainment purposes.
