Program and Application

A computer program or application is what allows people to perform tasks on the computer.  Each application is intended to accomplish a specific task.  Applications are sometimes free, sometimes cheap, and sometimes expensive.  When you open an application, you can use its features, and when you are finished using it, you can save your work, and then quit the application to signal that you have finished using it for the time being.

Examples
One popular application is Microsoft Word.  This application is a word processor: it lets you type and read documents and letters.

Another application is Internet Explorer.  This application is a web browser: it lets you enter web addresses and view web sites on the Internet.

A third application is iTunes.  This application lets you organize and listen to music, movies, and TV shows on your computer.  It also lets you buy new music, movies, and shows from the Internet, and transfer songs to an iPod.
