lesson objectives
Lesson Objectives
  • Define and give examples of application software and application suites
  • Identify a file type by looking at its extension
  • Identify the specific application software needed to open a given file
  • Identify the uses for a given application software
  • Demonstrate how to create, name, organize, copy, move, and delete files and folders

application software
Application Software
  • “I’ve got an app for that” - App is short for application software
  • Application software:
    • a computer program that performs a specific function(s) for the user
    • A group of applications packaged together are called a Suite

application software1
Application Software
  • Examples of applications:
    • Google Earth application software locates and gives a virtual picture of any place on earth
    • Windows Media Player application software plays songs and videos
  • Examples of Suites:
    • Microsoft Office is a package that bundles Word, Excel, PowerPoint, Publisher and Access together
    • Adobe offers various Suites containing Photoshop, Flash, and other Designing applications

file extensions
File Extensions
  • Using the “my computer” icon or “my files” icon/folder, you can view a list of files contained on your computer
  • Each file displays an icon, the filename, and an extension
  • The filename is followed by a period and then an extension

file extensions1
File Extensions
  • You can identify a file by its extension
  • .doc and .docx are Microsoft Word documents
  • .doc represents a Word document created for version 2003 or less
  • .docx represents a Word document created for version 2007 or higher

File Extensions
  • Pictures, images and graphics can also be identified by their extensions
  • Common graphic extensions are:
    • .bmp - bitmap
    • .gif – Graphics Interchange Format
    • .jpg or .jpeg – Joint Photographic Experts Group
