  1. Computer software

  2. Software Software- Software are programs or instructions that a computer must follow to do its task. The purpose of software is to process data into useful information for people. Software today often has a graphical user interface. With a graphical user interface (GUI pronounced gooey), you interact with the software using text, graphics, and visual images such as icons.

  3. An icon is a miniature image that represents a program, an instruction, or some other object.

  4. Categories of software The two categories of software are system software and application software. System Software System software consists of the programs that control or maintain the operations of the computer and its devices. System software serves as the interface between the user, the application software, and the computer’s hardware. Two types of system software are the operating system and utility programs.

  5. Two types of system software are the operating system and utility programs. Operating System An operating system is a set of programs that coordinates all the activities among computer hardware devices. It provides a means for users to communicate with the computer and other software. Many of today’s computers use Microsoft’s Windows or Mac OS, Apple’s operating system.

  6. Utility Program A utility program allows a user to perform maintenance-type tasks usually related to managing a computer, its devices, or its programs. For example, you can use a utility program to transfer digital photos to an optical disc. Most operating systems include several utility programs for managing disk drives, printers, and other devices and media. You also can buy utility programs that allow you to perform additional computer management functions.

  7. Application Software Application software consists of programs designed to make users more productive and/or assist them with personal tasks. A widely used type of application software related to communications is a Web browser, which allows users with an Internet connection to access and view Web pages or access programs.

  8. Other popular application software includes word processing software, spreadsheetsoftware, database software, and presentation software. • Many other types of application software exist that enable users to perform a variety of tasks. These include personal information management, note taking, project management, accounting, document management, computer-aided design, desktop publishing, paint/image editing, audio and video editing, multimedia authoring, Web page authoring, personal finance, legal, tax preparation, home design/landscaping, travel and mapping, education, reference, and entertainment (e.g., games or simulations).

  9. Installing and running programs Installing is the process of setting up software to work with the computer, printer, and other hardware. When you buy a computer, it usually has some software preinstalled on its hard disk. To begin installing additional software from an optical disc, insert the program disc in an optical disc drive. To install downloaded software, the Web site typically provides instructions for how to install the program on your hard disk.

  10. To begin installing additional software from an optical disc, insert the program disc in an optical disc drive. To install downloaded software, the Web site typically provides instructions for how to install the program on your hard disk.

  11. Once installed, you can run the program. When you instruct the computer to run an installed program, the computer loads it, which means the program is copied from storage to memory. Once in memory, the computer can carry out, or execute, the instructions in the program so that you can use the program.

  12. Software development A programmer, sometimes called a developer, is someone who develops software or writes the instructions that direct the computer to process data into information. Complex programs can require thousands to millions of instructions. Programmers use a programming language or program development tool to create computer programs.

  13. Application Software Application software consists of programs designed to make users more productive and/or assist them with personal tasks. Application software has a variety of uses: 1. To make business activities more efficient 2. To assist with graphics and multimedia projects 3. To support home, personal, and educational tasks 4. To facilitate communications

  14. Four categories of Application Software 1. Business 2.Graphics and Multimedia 3. Home/personal/Educational 4. Communications

  15. Business software Business software is application software that assists people in becoming more effective and efficient while performing their daily business activities. Business software includes programs such as word processing, spreadsheet, database, presentation, note taking, personal information manager, business software for phones, business software suites, project management, accounting, document management, and enterprise computing software.

  16. Word processing Word processing software, sometimes called a word processor, allows users to create and manipulate documents containing mostly text and sometimes graphics. Millions of people use word processing software every day to develop documents such as letters, memos, reports, mailing labels, newsletters, and Web pages. A major advantage of using word processing software is that users easily can change what they have written. Word processing software also has many features to make documents look professional and visually appealing. For example, you can change the shape, size, and color of characters; apply special effects such as three-dimensional shadows.

  17. Examples of word processing Microsoft Word Apple Pages Corel WordPerfect

  18. Spreadsheet Software allows users to organize data in rows and columns and perform calculations on the data. These rows and columns collectively are called a worksheet . Most spreadsheet software has basic features to help users create, edit, and format worksheets.

  19. Examples of spreadsheet Microsoft Excel OpenOfficeCalc AppleNumbers

  20. Database Software A database is a collection of data organized in a manner that allows access, retrieval, and use of that data. In a manual database, you might record data on paper and store it in a filing cabinet. With a computerized database, the computer stores the data in an electronic format on a storage medium such as a hard disk.

  21. Database software is application software that allows users to create, access, and manage a database. Using database software, you can add, change, and delete data in a database; sort and retrieve data from the database; and create forms and reports using the data in the database.

  22. With most personal computer database programs, a database consists of a collection of tables, organized in rows and columns. Each row, called a record, contains data about a given person, product, object, or event. Each column, called a field, contains a specific category of data within a record. Example:Corel Paradox Microsoft Access Sun MYSQL

  23. Presentation Software is application software that allows users to create visual aids for presentations to communicate ideas, messages, and other information to a group. The presentations can be viewed as slides, sometimes called a slide show, that are displayed on a large monitor or on a projection screen

  24. Presentation software typically provides a variety of predefined presentation formats that define complementary colors for backgrounds, text, and graphical accents on the slides. This software also provides a variety of layouts for each individual slide such as a title slide, a two-column slide, and a slide with clip art, a chart, a table, or a diagram. In addition, you can enhance any text, charts, and graphical images on a slide with 3-D, animation, and other special effects such as shading, shadows, and textures.

  25. When building a presentation, users can set the slide timing so that the presentation automatically displays the next slide after a preset delay. Presentation software allows you to apply special effects to the transition between slides. One slide, for example, might fade away as the next slide appears.

  26. Example: Microsoft Powerpoint Apple Keynote Impress Corel Presentations

  27. Note Taking Software Note taking software is application software that enables users to enter typed text, handwritten comments, drawings, or sketches anywhere on a page and then save the page as part of a notebook. Users also can include audio recordings as part of their notes. Users find note taking software convenient during meetings, class lectures conferences, in libraries, and other settings that previously required a pencil and tablet of paper for recording thoughts and discussions.
