A program or group of programs designed for end users .Software can be divided into two general classes: systems software and applications software . Systems software consists of low-level programs that interact with the computer at a very basic level. This includes operating systems, compilers , and utilities for managing computer resources . In contrast, applications software (also called end-user programs ) includes database programs, word processors , and spreadsheets . Figuratively speaking, applications software sits on top of systems software because it is unable to run without the operating system and system utilities.
An applet is a small Java program that is embedded into an HTML page. The applet is not allowed access to certain resources on the computer such as files and drives and the applet is prohibited from communicating across networks.
A file attached to an e-mail message. Many e-mail systems only support sending text files as e-mail. If the attachment is a binary file or formatted text file (such as an MS-Word document), it must be encoded before it is sent and decoded once it is received. There are a number of encoding schemes, the two most prevalent being Unicode and MIME.

(v.) 1. To prepare a storage medium , usually a disk , for reading and writing . When you format a disk, the operating system erases all bookkeeping information on the disk, tests the disk to make sure all sectors are reliable, marks bad sectors (that is, those that are scratched), and creates internal address tables that it later uses to locate information. You must format a disk before you can use it. Note that reformatting a disk does not erase the data on the disk, only the address tables. Do not panic, therefore, if you accidentally reformat a disk that has useful data. A computer specialist should be able to recover most, if not all, of the information on the disk. You can also buy programs that enable you to recover a disk yourself. 2. To specify the properties, particularly visible properties, of an object . For example, word processing applications allow you to format text , which involves specifying the font ,alignment ,margins , and other properties.

Abbreviated GUI (pronounced GOO-ee ). 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. Graphical user interfaces, such as Microsoft Windows and the one used by the Apple Macintosh , feature the following basic components:
* pointer: a symbol that appears on the display screen and that you move to select objects and commands . Usually, the pointer appears as a small angled arrow. Text -processing applications, however, use an I-beam pointer that is shaped like a capital I.
* pointing device: A device , such as a mouse or trackball , that enables you to select objects on the display screen.
* icons: Small pictures that represent commands, files , or windows . By moving the pointer to the icon and pressing a mouse button , you can execute a command or convert the icon into a window. You can also move the icons around the display screen as if they were real objects on your desk.
* desktop: The area on the display screen where icons are grouped is often referred to as the desktop because the icons are intended to represent real objects on a real desktop.
* windows: You can divide the screen into different areas. In each window, you can run a different program or display a different file. You can move windows around the display screen, and change their shape and size at will.
* menus: Most graphical user interfaces let you execute commands by selecting a choice from a menu.

A special type of database system , in which objects (text , pictures, music, programs) can be creatively linked to each other. When you select an object, you can see all the other objects that are linked to it. You can move from one object to another even though they might have very different forms. For example, while reading a document about Mozart, you might click on the phrase Violin Concerto in A Major, which could display the written score or perhaps even invoke a recording of the concerto. Clicking on the name Mozart might cause various illustrations of Mozart to appear on the screen. The icons that you select to view associated objects are called Hyperlinks or buttons.

Netscape is a web browser that was originally based on a program called Mosaic. Netscape is also the name of the company.
The most important program that runs on a computer . Every general-purpose computer must have an operating system to run other programs. Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk , and controlling peripheral devices such as disk drives and printers. Think of it as a secretary between you and your computer.
Operating systems provide a software platform on top of which other programs, called application programs, can run. The application programs must be written to run on top of a particular operating system. For PCs , the most popular operating systems are DOS, OS/2 , and Windows, but others are available, such as Linux .
Adobe Portable Document Format File (see Sect. 2-File Formats Summary)
Are software applications that add a specific feature or service for a variety of media uses. Web plug-ins , such as Flash, allow the transfer, viewing, and interaction with websites, downloaded movies, sound, online databases and more.For example, there are number of plug-ins for the Netscape Navigator browser that enable it to display different types of audio or video messages. Navigator plug-ins are based on MIME file types. See Browser plug-in directory, Section X)
A window that suddenly appears (pops up) when you select an option with a mouse or press a special function key . Usually, the pop-up window contains a menu of commands and stays on the screen only until you select one of the commands. It then disappears.
Also, a type of window that appears over the browser window of a Web site when visited by a user. In contrast to a pop-under ad , which appears behind the browser window. A pop-up is more obtrusive as it covers other windows, particularly the window that the user is trying to read. Pop-ups ads are used extensively in advertising on the Web, though advertising is not the only application for pop-up windows . These should be turned off when using UNCG / DCL online courses. You can do this by going into “preferences” in your web browser.
A special kind of pop-up window is a pull-down menu, which appears just below the item you selected, as if you had pulled it down.

Is a multimedia development, storage, and playback technology from Apple. Quicktime files combine sound, text, animation, and video in a single file. Quicktime files can be recognized by their file name extensions: qt, mov, and moov. Also used to play MPEG files. (see Sect. 2-Plug-in Directory/Multi-Media Plug-ins).
Is the place in a computer where the operating system, application programs, and data in current use are kept so that they can be quickly reached by the computer’s processor. RAM is much faster to read from and write to than the other kinds of storage in a computer: the hard disk, floppy disk, and CD-ROM. However, the data in RAM stays there only as long as your computer is running. When you turn the computer off, RAM loses its data. When you turn your computer on again, your operating system and other files are once again loaded into RAM, usually from your hard disk.
RAM can be compared to a person’s short-term memory and the hard disk to the long-term memory. The short-term memory focuses on work at hand, but can only keep so many facts in view at one time. If short-term memory fills up, your brain sometimes is able to refresh it from facts stored in long-term memory. A computer also works this way. If RAM fills up, the processor needs to continually go to the hard disk to overlay old data in RAM with new, slowing down the computer’s operation. Unlike the hard disk which can become completely full of data so that it won’t accept any more, RAM never runs out of memory. It keeps operating, but much more slowly than you may want it to.
Is a continuous or streaming sound technology from Progressive Networks’ RealAudio. A RealAudio player or client program may come included with a Web browser or can be downloaded. (see Sect. 2-Browser Plug-ins)
