Software Essentials ICT 1 & 2
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.
Cloud Computing • Cloud Applications run within a browser • This means they can run on any operating system • Examples of Cloud Computing Software: • Google Docs • Office 365
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.
ICT 1 – Activity: Identifying File Types • classify file types according to their file name extensions
ICT 2 – Activity: Software Essentials Matching • match common terms associated with software to their definitions
