From the tasks that you have carried out, you will have noticed a number of facilities or characteristics for each type of application package. For example, if you were telling a friend how a word processor might be used, you might say that:

• it is useful for producing a range of documents, such as letters and reports
  
• it includes proofing tools to check spelling and sometimes grammar
  
• the appearance of text can be changed.

Your description of other types of application packages would be considerably different.
