Identity 
Till now, trained specialists were needed to perform many of the operations that you now perform on your personal computer. Market analysts used calculators to sell projects. Graphic artists creating handmade designs. Creating electronic files to store data processing class on large computers, now all this work and many more - you can do with a personal computer and the right application software. Think of a personal computer as an electronic tool. You may think that you are typing, calculating, organizing information, presenting or Managing is not good. But, a personal computer can help you do all these things and much more. All you need is the right software.
To use computers efficiently and effectively, you need to understand the functionality of general-purpose application software, which includes word processors, spreadsheets, presentation programs, and database management systems. You also need to know about the packages and software suites involved.
Application software can be divided into three categories. There is a category, General - Purpose Applications, which includes Word Processing Programs, Spreadsheets, Presentation Graphics, and Database Management Systems. The second category is specialized applications, which include thousands of other programs that focus on specific topics and business-related tasks. The third category is mobile apps, which are add-on features or programs designed for smartphones and tablets.
User Interface
The user interface is the part of the application that lets you control and interact with the program. Depending on the application, you can use the mouse, pointer, keyboard, and / or your voice to interact with the application. Most general-purpose applications use a mouse or professional user interface (GUI) that displays graphical elements to represent familiar objects, called icons. The mouse controls the pointer on the screen to select items like icons. Another feature is the use of Windows to display information. A window is a rectangular area that can contain a document, program, or message. (Do not confuse the term window with Microsoft's Windows operating systems, which are programs.) More than one window can be opened and displayed on a computer screen at a time.
Traditionally, most software programs use a system of menus, toolbars, and dialog boxes.
- Provides menu commands that are usually displayed in the menu bar at the top of the screen.
- Toolbars usually appear at the bottom of the menu bar and contain graphic elements called buttons that provide shortcuts for quick access to commonly used commands.
- Dialog boxes provide additional information and request user input. Many applications, especially Microsoft applications, use an interface called the Ribbon GUI to find and use all the features; This GUI uses a system of ribbons, tabs and galleries.
- Ribbons replace ribbons menus and toolbars by organizing them into commonly used commands tabs. These tabs display command buttons that are most relevant to the task the user is performing.
- Uses tabs to divide ribbons into major activity areas. Each tab is then organized into groups that contain related items. Some tabs, called contextual tabs, appear only when needed and predict what the user will do next.
- Galleries simplify the selection process from a list of options. This is achieved by graphically displaying the effects of the options before selecting.
Common Features
Most applications offer a variety of features for entering / presenting, editing and formatting documents. Some of the most common features include
- Spell Checker - detects misspelled words.
- Alignment Centers, Right - Alliance or Left - Alliances, Numbers and Characters.
- Fonts and font sizes (perhaps using character effects) - especially the size and style of entered numbers and text.
- Character Effects - Offers a variety of typefaces, such as bold or italics.
- Editing Options - Provides easy ways to edit text, such as cut, copy and paste
General - Purpose Applications
As mentioned earlier, General - Purpose applications include word processors, spreadsheets, presentations.
Word Processors
Word Processors create text-based documents and are the most flexible and widely used software tools. All kinds of people and organizations use word processors to create memos, letters and faxes. Organizations create newsletters, manuals, and brochures to inform their customers. Students and researchers use word processors to create reports.
Microsoft Word are the most widely used word processors. Other popular word processors include Apple Pages, Google Docs, WordPerfect and OpenOffice Writer.
