9. software license  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)

10. 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.

11. System Software  3 common operating system software for desktops and laptops  Microsoft Windows  Mac OS  Linux

12. Microsoft Windows  commercial software installed on desktops  Most popular  suffers many virus attacks

13. Mac OS  introduced before Windows  installed only on Apple computers  not as many viruses as Windows

14. Linux  open source software installed on desktops  not as widely used  popular with Techies  can run on older machines  hardly any virus attacks

15. Try it out!  Follow along with me as we explore the Microsoft Operating System  use gadgets, icons, and taskbars  calculator, text editor, clock, volume controls,  add icons and shortcuts to taskbar and shortcut menus

16. Tablet and Smartphone Operating System Software

17. 3 most common mobile operating systems:  Google Android  Apple iOS  Windows Phone

18. Google Android  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  highly customizable, making it a favorite for technology-savvy consumers

19. Apple iOS  installed only on Apple smartphones and tablets  Sleek and simple user interface with icon-based home screen  Can’t customize it easily  Preloaded with an online store called the App Store

20. Windows Phone  Not as popular  Developed years after Android and iOS  Uses “Live Tiles” that provide live updates on home screen  online store - Windows Marketplace  Not as many apps as Apple or Google

21. Application Software

22.  allows users to perform specific tasks on their computers.  Examples:  writing letters  preparing budgets  playing games  sending e-mails  browsing the internet

23. Types of Application Software Application Software Type FunctionExamples Web Browserview webpages on the InternetInternet Explorer, Google Chrome, Apple Safari E-mail Clientsend and receive e-mailsMicrosoft Outlook, Windows Live Mail Word Processorcreate documents - letters, flyersMicrosoft Word, Google Docs Presentation (slide show) create presentationsMicrosoft PowerPoint, Google Slides Spreadsheetscreate documents that can perform calculations. Creates tables, charts, and graphs Microsoft Excel, Google Sheets

24. 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

25. File Management  managing files and folders correctly prevents wasted time, frustration and errors.  proper file management begins with using file naming conventions and good organization.

26. 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.
