This part will deal with the three most popular application programs: word processor, spreadsheet, and database. Unlike operating systems (that oversee the general work of the computer), these programs are intended to help the users to carry out specific tasks. They can be utilised to manipulate text, numbers, or graphics, and modern ones usually combine all three features. Application packages (for example the Microsoft Office package) are also quite popular; they offer a good integration of their applications so that switching among them can greatly enhance the general performance of your work.

Another application that is very popular and useful is the image editor. It is specifically dedicated to modify pictures and create image effects. There are many of them, from simple to professional ones. This kind of application will not be dealt with here but you can easily find information about various image editors at the following Internet site: http://www.html.it/psp/index.html which is in Italian and contains a number of tutorials on Paint Shop Pro, one of the most popular image editors (if you browse through the website you will also find materials and information on other image editors).
