Objective of this learning outcome
On this learning outcome we have to consider three basic terms
1. What is software?
2. What is upgrading Means?
3. What are the requirement that helps to upgrade a software?

5.  Computer Software
 determines the tasks a computer can help you accomplish. Some
software helps you create documents, while other software helps you
block viruses or fine-tune your computer’s performance.
 the characteristics of application software, utilities, and device drivers
 What is software?
 Is the instructions that tell a computer how to carry out a task are
referred to as a computer program.
 These programs form the software that prepares a computer to do a
specific task, such as document production, photo editing, virus
protection, file management, or Web browsing.

6. Software
 The two main categories are
1. System Software and
2. Application software.
 System Software
 System software is designed for computer-centric tasks, whereas application
software is designed to help people accomplish real-world tasks.
 For example, you would use system software to diagnose a problem with your
hard disk drive or Internet connection, but you would use application software
to edit a photo or write a term paper.
 System software includes operating systems , utilities, and device drivers.
 Application Software
 Application software can be divided into subcategories according to its use.

7. Application software
 Why is it called application software?
 Application software utilizes the capacities of a computer directly
for a dedicated task. Application software is able to manipulate
text, numbers and graphics.
 It can be in the form of software focused on a certain single task
like word processing, spreadsheet or playing of audio and video
files.
 A computer certainly has many uses, such as creating documents,
crunching numbers, drawing designs, and editing videos.
 Each use is considered an application, and the software that
provides the computer with instructions for each use is called
application software, an application, or simply an app.

8. Productivity software
 What is productivity software?
 Some types of application software are referred to as productivity
software.
 Many different definitions exist for this popular term. In general, however,
productivity software can be defined as any type of application software
that has the potential to help people do their work more efficiently.
 The term might have originated in reference to software tools used by
businesses to increase secretarial efficiency at routine office tasks, such as
typing, filing, and basic bookkeeping.
 The applications that are most commonly associated with productivity
software include word processing, spreadsheets, schedulers, and database
management systems.
 Graphics software, presentation software, and desktop publishing software
are also sometimes classified as productivity applications.

9. Utility software
 What is utility software?
 A type of system software called utility software is designed to help
you monitor and configure settings for your computer system
equipment, the operating system, or application software.
 Like all system software, utilities focus on computer-centric tasks such
as blocking viruses or diagnosing hard disk errors, rather than real-
world tasks such as document production or accounting. Examples of
utility software include setup wizards, communications programs,
security software, and diagnostic tools

10.  In recent years, antivirus products, such as Norton Antivirus, McAfee
Virus Scan Plus, and a vast! Antivirus, have been a popular category
of utility software

11. DEVICE DRIVERS
What is a device driver?
 A device driver is software that helps a peripheral
device establish communication with a computer.
 This type of system software is used by printers,
monitors, graphics cards, sound cards, network cards,
modems, storage devices, mice, and scanners.
 Once installed, a device driver automatically starts
when it is needed.
 Device drivers usually run in the background, without
opening a window on the screen.

13. Common Types of Application SW
 Word Processing Software:
 This software enables users to create and edit documents. The most popular
examples of this type of software are MS-Word, WordPad and Notepad
among other text editors.
 Database Software:
 Database is a structured collection of data. A computer database relies on
database software to organize data and enable database users to perform
database operations. Database software allows users to store and retrieve
data from databases. Examples are Oracle, MS Access, etc.
 Spreadsheet Software:
 Excel, Lotus 1-2-3 and Apple Numbers are some examples of spreadsheet
software. Spreadsheet software allows users to perform calculations using
spreadsheets. They simulate paper worksheets by displaying multiple cells that
make up a grid.

14.  Multimedia Software:
 They allow users to create and play audio and video files. They are
capable of playing media files. Audio converters, audio players, burners,
video encoders and decoders are some forms of multimedia software.
Examples of this type of software include Real Player and Media Player.
 Presentation Software:
 The software that is used to display information in the form of a slide show is
known as presentation software. This type of software includes three
functions, namely, editing that allows insertion and formatting of text, methods
to include graphics in the text and a functionality of executing slide shows.
Microsoft PowerPoint is the best example of presentation software.
 Enterprise Software:
 It deals with the needs of organization processes and data flow. Customer
relationship management or the financial processes in an organization are
carried out with the help of enterprise software.
Common Types of Application SW

15.  Information Worker Software:
 Individual projects within a department and individual needs of creation and
management of information are handled by information worker software.
Documentation tools, resource management tools and personal management
systems fall under the category of this type of application software.
 Educational Software:
 It has the capabilities of running tests and tracking progress. It also has the
capabilities of collaborative software. It is often used in teaching and self-
learning. Dictionaries like Britannica and Encarta, mathematical software like
Matlab and others like Google Earth and NASA World Wind are some of the
well-known names in this category.

group of applications combined to perform related functions.
 OpenOffice.org and Microsoft Office are the best examples of this type of
application software.
 These application suites, as you know, come as bundles of applications like word
processors, spreadsheets, presentation software, etc. Applications in the suite can
work together or operate on each other's files.
Common Types of Application SW

17.  Software that aid Engineering and Development of Products:
 These software are used in the design and development of hardware and software
products.
 Integrated development environments (IDE) and computer language editing tools falls
under this type of application software.
 Interestingly, software products are developed using other software, and software
communicate with one another through software.
 Application programming interfaces which aid the communication of two or more
software, are examples of this application software type.
Common Types of Application SW

18. cont.……
 Application software are available in different forms such as.
 Licensed:
 A majority of software applications are licensed and not sold.
 In this case, a user purchases a software license and not the
software itself.
 The vendor allows for the installation of this software on a
specific number of machines.
 Sometimes, the license is limited to a certain number of users.
Most software licenses allow you to run the application on only
one machine, although you are allowed to copy the software on
other machines for backup purposes.
 Licenses disallow the resale of software.

19.  As Freeware:
 Application software that can be downloaded, used and copied
without any restrictions is known as freeware.
 Generally small programs are released as freeware and are open
for use.
 Sold:
 As opposed to licensed software, these software are sold to users.
 You need to purchase this type of software from the vendor in which
case, you own a legitimate copy of the software.
 This allows you to resale the software.

20. Cont..
 As Shareware:
 These application software can be downloaded but you need to pay
some amount for using them. Generally, mid-size software developed
by software companies are made available as shareware.
 Open Source:
 Open source software, as their name suggests, are made available
with their source code.
 The code is open for modification and use.
 People mistake open source software for free. But note that here,
'free' refers to the freely available source code, thus making the
software open for further development by users.

21.  Needs to be Installed:
 This is true with many application software; for example
spreadsheet software, word processors, data management
software, etc. They need to be installed on your computer hard
drive for use.
 Runs Online:
 Antivirus software runs online. Similarly, Internet games that you
can play online and which don't need to be downloaded fall
under this category.
 Simply put, application software are software designed for specific
purposes, or meant for specific applications. Application software are of
great use in completing individual and organizational tasks, as they have
user-friendly features and are easy and interactive to use.

22. Upgrading

23. Upgrading
 Term used to describe updating a software program
or adding a new hardware.
 With software, an upgrade allows a user to get the
latest version of a software program at a discounted
price and not have to purchase the full product.
 For example, a user running Microsoft Windows 95
could purchase the Microsoft Windows 98 upgrade for
a low price when compared to the full version of
Windows 98.

24.  Below are a few reasons and benefits of upgrading your software products to
the latest version.
1. New features not available or found in previous versions.
2. Often, the new version of a program will have better stability and
increased performance.
3. After so long an older software program will be discontinued and
often no longer supported.
Tip:
Upgrading and updating: a software program are two different things.
When upgrading a software program you will almost always have to
purchase the upgrade. However, most updates are small and usually free
programs that can be run to update the program.

25.  A hardware upgrade such as a memory upgrade may not
require a user to remove the memory from the computer because
of the availability of additional expansion slots.
 Below is a few reasons and benefits a user should expect to see
when upgrading a hardware device.
 Performance increase.
 The majority of the hardware upgrades performed are
done to increase the performance of the computer.
 Compatibility.
 A user may upgrade one or more components in their
computer to be able to run or use a software program.

26. Conti…..
 Capacity increase.
 Users may upgrade or add a new device to increase the
overall capacity of the computer.
 For example, adding a new hard drive to allow the
computer to store more information; or increase the memory
to increase the ability of what programs can be opened
and also at the same time increase the performance.

27.  A software update
 provides bug fixes and minor software enhancements and is made
available by free download.
 Software updates sometimes include new drivers to support the latest
hardware such as printers, CD drives and DVD drives.
 A software update is sometimes called a software patch because it is
applied over software that you already have installed.
 A software update does not provide a full software package
installation.
 A software upgrade
 is a purchase of a newer version of software you currently use of a
more fully-featured version of your current software. There is usually a
cost for a software upgrade, although you can often upgrade at a
reduced price.
