- Abbreviated GUI. A program interface that takes advantage of the computer's graphics capabilities to make the program easier to use. Well-designed graphical user interfaces can free the user from learning complex command languages. On the other hand, many users find that they work more effectively with a command-driven interface, especially if they already know the command language. It features a few basic components such as pointer, windows, menu and icons.
Word Processor.
- Programmable typewriter or computer program used to compose, format, sort, and rearrange text upon command and sometimes perform other related functions such as correcting misspelled words. Word processors are commonly used to compose copy and to create personalized computer letters to customers or prospects using standard formats with spaces for inserting information specific to that customer.
Spreadsheet.
- Spreadsheet applications (sometimes referred to simply as spreadsheets) are computer programs that let you create and manipulate spreadsheets electronically. In a spreadsheet application, each value sits in a cell. You can define what type of data is in each cell and how different cells depend on each other. Once you have defined the cells and the formulas for linking them together, you can enter your data. You can then modify selected values to see how all the other values change accordingly. This enables you to study various what-if scenarios. A simple example of a useful spreadsheet application is one that calculates mortgage payments for a house.
Database Management System.
- A collection of programs that enables you to store, modify, and extract information from a database. There are many different types of Database Management Systems, ranging from small systems that run on personal computers to huge systems that run on mainframes.
Utility suites.
- PC utilities are programs that are designed to help with maintenance of the system and to keep it free from errors. However, this is an oversimplification. There are many different components that go into such software and work together. Here, we shall take a look at some of the components of the best PC utility software suites. One of the first, and most critical, utilities that is included in virtually all utility software is a backup utility. This program creates a copy of the system and all files on the computer. Sometimes the backup is only for certain types of files prior to making an update to the system. Other times, one can backup the entire system and all files to a portable storage device. This option should be used at least weekly to ensure that one has the necessary files to correct problems should something be damaged or deleted.
