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.

Interface  An interface is a software application's onscreen appearance, including the tools provided for users to issue commands and access features.  There are 2 types:  Command Line Interface  Graphical User Interface (GUI)

Command Line Interface  Text-based interface that does not support a mouse  Example: Windows DOS

Graphical User Interface (GUI)  Allows users to click and drag onscreen objects with the mouse  Also called point-and-click interface  Examples: Microsoft, Apple

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)

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  Most popular  suffers many virus attacks

Mac OS  introduced before Windows  installed only on Apple computers  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  hardly any virus attacks

Tablet and Smartphone Operating System Software

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

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

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

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

Application Software

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

Types of Application Software Application Software Type FunctionExamples Web Browserview webpages on the InternetInternet Explorer, Google Chrome, Apple Safari Clientsend and receive sMicrosoft 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

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 prevents 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. File TypeExtension Portable Document Format (PDF).pdf Microsoft Word Document.doc,.docx Microsoft Excel Spreadsheet.xls,.xlsx Plain Text File.txt Webpage.htm,.html Compressed File.zip,.rar,.tar Audio File.wav,.mp3,.ogg Video File.avi,.wmv,.mp4,.mpg Graphics File.jpg,.png,.gif
