What is software?
software is the set of instructions stored inside a computer
These instructions tell the computer how to work with the hardware.
They also enable the user to communicate with the computer.
software license
allow you to run the program on 1 or 2 machines and make copies of the software for backup purposes.
protects the software developer from people buying and selling illegal copies
2 types of licenses: Commercial – the user pays a fee for permission to use the software
(Microsoft, Adobe)
Open Source - software whose source code is free. Anyone can change, copy, or distribute it. (Linux, Apache)
two basic types of computer software
Operating System Software - Directs all the activities and sets all the rules for how the hardware and software will work together.
Application Software - Programs that work with operating system software to help the computer to do specific types of work.
System Software 3 common operating system software for desktops and
laptops
Microsoft Windows
Mac OS
Linux
Microsoft Windows commercial software installed on
desktops
dominates the market
supports largest amount of application software
suffers many virus attacks
Mac OS introduced before Windows
commercial software installed only on Apple computers
not as many application software as Windows
not as many viruses as Windows
Linux open source software
installed on desktops
not as widely used
popular with Techies
can run on older machines
very few application software available
hardly any virus attacks
Tablet and Smartphone Operating System Software
3 most common mobile operating systems: Google Android Apple iOS Windows Phone
Google Android
Very large market share because it can be installed on almost every type of smartphone and tablet
Uses icon- and widget-based home screen
Preloaded with an online store called Google Play, which allows users to download millions of audio tracks, movies, TV shows and applications
Google Play offers both paid apps and free apps
Google Android is highly customizable, making it a favorite for technology-savvy consumers
Apple iOS
Large market share, but limited because it is installed only on Apple smartphones and tablets
Sleek and simple user interface with icon-based home screen
Very limited in customizability
Preloaded with an online store called the App Store
The App Store is similar to Google Play in that it offers millions of paid and free multimedia downloads
Windows Phone
Smallest market share compared to Android and iOS
Developed years after Android and iOS
Uses “Live Tiles” that provide live updates on home screen instead of icons to open the related apps
Preloaded with an online store called Windows Marketplace
Windows Marketplace has substantially fewer apps available compared to its competitors
ICT 1 Activity – software essentials word search
Use the handout to identify various terminology associated with computer software
ICT 2 Activity - Creating and Moving Files
Follow along with the “Creating and Moving Files” Handout to learn how to create folders and move files
Application Software
Application software allows users to perform specific tasks on their computers.
Examples: writing letters, preparing budgets, playing games, sending and receiving e-mails, browsing the internet.
Types of Application SoftwareApplication Software Type

File Management
managing files and folders correctly can prevent wasted time, frustration and errors.
proper file management begins with using file naming conventions and good organization.
guidelines for naming files and folders:
Use short, simple file and folder names
Use file and folder names that describe the content accurately.
Use underscores instead of spaces in file names. For example: descriptive_essay
Use all lowercase letters in file names.
Avoid using characters such as: ! # $ % @ ^ ` ~ + ; = in file and folder names. Some systems do not allow you to use characters in file and folder names, and will not accept them.
File Extensions A file extension is the suffix at the end of a filename that
indicates what type of file it is.
