INSTALLING A SOFTWARE

When purchasing a personal computer, it already contains

software such as :

•

Operating system

•

Utility Programs

•

Basic Applications

•

A Setup Program: It is included with the software to guide

you

through

the

installation

steps

and

prepare

the

software you use on your computer.

INSTALLING A SOFTWARE

Four types of Software

• Application Software
• Window apps
• Mobile apps
• Utility Programs such as drivers and

system tools.

Desktop or Laptop

Desktop application
Windows app
Desktop operating system
other system software

Tablet or smartphone

Mobile app

Mobile operating system

OVERVIEW OF
INSTALLATION SETUP

Three distribution methods:
•

CD or DVD

•

Compressed file (on a web site, app App store

Window Store or Apple Store

OVERVIEW OF
INSTALLATION SETUP

The setup program guides you through the
setup

to

install

the

software,

including

choosing the component
You want to install and select a folder for the
software.

OVERVIEW OF
INSTALLATION SETUP

A web site provided by a software developer
or publisher. The software and program are
contained

in

a

single

compressed

file

available on the web site.

OVERVIEW OF
INSTALLATION SETUP

Store apps such as the Windows Store, the
Apple Store, and Google Play Store provided
access to apps designed for the particular
operating system

INSTALLATION TASKS

•Copies files: The setup program copies files from the distribution to your hard disk, and
then creates a log to indicate where it stores files during installation.

•Extract Files: if the files are stored in a compressed file, the setup program extracts them so
they can all be used in the installation. The setup might also create folders and subfolders
for the files.

•Check for existing versions of the software: The setup program scans for other versions of
the software if it finds an earlier version, it might need to install it first or it might be able to
use files already on your computer.

•Verifies system requirement: The setup program checks system components, such as RAM
and the hard drive, to make sure they have enough capacity to run and store the software.

•Find drivers and other system files: If you are installing application software, the setup
program looks for and activates the drivers the software uses. Such as printer drivers, also
look for system files it might need to provide services such as Internet access.

•Updates system files: the setup program provides configuration data to the operating
system so it can run the software. On a Windows computer, this information is stored in
the window Registry, a database of information about your computer’s configuration.

•Provides a way to start the software: The setup program adds a button, icons, or tile to the
graphical user interface so you can start the software.

REINSTALLING SOFTWARE

• If you have installed software, but it not working properly

you can reinstall it.

• Uninstall the software as described in the “uninstalling

software.

• Restart the computer. Reset the computer and free

system resources, greatly reducing the possibility of
corrupting a file.

• Install the software in the “installing software” if possible,

and select a website or store app as the distribution
location so you can install a recent version of the software.

• . If the setup program prompts you to check for and install

updates, choose the option to do so. In most cases, it is
best to install the most recent version available.

•

REINSTALLING AN
OPERATING SYSTEM

•

MAC OS X- You can reinstall MAC OS X by
choosing the restart command on the Apple
Menu and then holding down the command +R
keys as the computer restarts.

•

IOS: you reinstall or update IOS by connecting
your smartphone or tablet to the internet or to a
computer where iTunes software is installed.

•

Android: You can reinstall or update Android by
using the settings app. Select a command called
About Tablet or something, similar, and then
choose System Updates to check for an update
or reinstall Androids.

UNDERSTANDING
SOFTWARE LICENSE

•

When purchasing software, you do not actually
own the software. Instead, you are purchasing
a software license, a legal agreement that
specifies how you can install and use the
software.

•

Software is distributed using a single-user
license called a single-seat license, which gives
only one person the right to install and use the
software.

•

Single-user license Some software is
distributed using a site license( also called a
(network license or volume license)usually to an
organization.

UNDERSTANDING
SOFTWARE LICENSE

•The people and organizations that develop software determine
how to me it available to users, such as selling it through retail
stores and Websites so it earns a profit or proving free or for a
nominal fee to cover distribution expenses.

•Commercial software: Sold for profit Usually through retail stores
and Web sites.

•Custom software: is a type of commercial software that is not sold
in retail outlets. Instead, an organization contracts with one or more
programmers or programming companies to develop software
that fits the organization’s unique needs.

•Shareware: is distributed free of charge as a download on the web,
often by single programmers who want to distribute their software
independently without packaging or advertising.

•Freeware: is software the developer makes available to users free of
charge.

•Public domain software: is the only type of software that is not
copyright.
