Basic and Specialized Software Application

Graphical User Interface (GUI)


GUI is a type of user interface that allows users to interact with electronic devices with images rather than text commands. It represents the information and actions available to a user through graphical icons and visual indicators such as secondary notation, as opposed to text-based interfaces,typed command labels or text navigation.

Word Processor


Word processor is using a computer to create, edit and print documents. Of all computer applications, word processing is the most common. To perform  word processing, you need a computer, a special program called word processor, and a printer. It also enables you to create a document, store it electronically on a disk, display it on screen, modify it by entering commands and characters from keyboard, and print it on a printer.

Spreadsheet

A spreadsheet is a computer application that simulates a paper, accounting worksheet. It displays multiple cells usually in a two-dimensional matrix or grid consisting of rows and columns. Each cell contains alphanumeric text, numeric values of formulas which define how the content of the cell is to be calculated from the content of any other cell( or combination of cells) each time any cell is updated.

DBMS

DBMS stands for data management system which is a collection of prgrams that help you to store, modify, and extract information from a database. There are plenty of different types of DBMSs, ranging from small systems that run on personal computers to huge systems which run on mainframes. Computerized library systems and flight reservation systems are the examples of database applications.

Utility Suites

Utility software is a kind of system software designed to help analyze, configure, optimize and maintain the computer. A single pieceof utility software is generally called a utility(abbr.util) or tool. It is for users to do things like creating text documents, playing games, listening to music or surfing the web.

Web Authoring

Web authoring is a category of software that enables the user to develop a web site in a dekstop publishinh format. The software generates the required HTML coding for the layout of Web pages based on what the user designs. Typically, the user can toggle back and forth between the graphical design and the HTML code and make changes to the Web page in either the design of the accompanying code.

Audio Editing Software

This audio editing software is a full featured professionalaudio and music editor for Windows and MacOSX. It lets you record and edit music, voice and other audio recordings. When editing audio files you can cut , copy and paste parts of recordings then add effects like echo, amplification and noise reduction. WavePad works as a wav or mp3 editor but it also supports a number of other file formats including vox, gsm,wma, real audio, au, aif, flac ogg and more.

Bitmap Image

A bitmap is a type of memory organisation or image filr format used to store digital images. The term bitmap comes from the computer programming terminology, meaning just a map of bits, a spatailly mapped array of bits. Raster images in general may be referred to as bitmaps whether synthetic or photographic, i files or memory.

Desktop Publishing Program

Desktop publishing program combines a personal computer and WYSIWYG page layout software to create publication documents on a computer for either large scale publishing or small scale local multifunction peripheral output and distribution.

HTML Editor

A HTML editor is a software application for creating web pages. Although the HTML markup of a web page can be written with any text editor, specialized HTML editors can offer convenience and added functionality. Many editors work not only with HTML, but also with related technologies such as CSS,XML and JavaScript or ECMAScript.

Image Editor

Image editor is a software that allows images to be edited and also converted to different graphic formats. Image editors typically deal with only bitmapped images such as GIFs, JPEGs and BMPs; however, some editors support both bitmaps and illustrations. Common functions are manually cropping and resizing the image and using ''filters'' to adjust bring brightness, contrast and colors. A myriad of filters are available for special effects.

Multimedia

Multimedia is media and content that uses a combination of different content forms. The term can be used as a noun( a medium with multiple conteny forms) or as an adjective describing a medium as having multiple content forms. The term is used in contrast to media which only use traditional forms of printed or hand-produced material.

 

Vector Image

Vector images is the use of geometrical primitives such as points, lines, curves, and shapes or polygon(s), which are all based on mathematical equations, to represent images in computer graphics. Its formats are comlementary to raster graphics, which is the representation of images as an array of pixels , as is typically used for the representation of photographic images.

The Internet, The Web & Electronic Commerce

URL

URL stands for Uniform Resource Locator which specifies where an indentified resource is available and the mechanism for retrieving it. The best- known example of the use of URLs is for the addresses of web pages on the World Wide Web, such as http://www.example.com/.

HTML

HTML ( Hyper text Markup Language) is a predominant markup language for web pages and also is the basic building-blocks of webpages. HTML is written in the form of HTML elements consisting of tags, enclosed in angle brackets (<html>), within the web page content. HTML tags normally come in pairs like <h1> and</h1>. The first tag in a pair is the start tag, the second tag is the end tag( they are also called opening tags and closing tags). In between these tags web designers can add text, tables, images, etc.

Javascript

Javascript is a prototype-based, object-oriented scripting language that is dynamic, weakly typed and has the first class functions. It  is also considered a functional programming language like Scheme and OCaml because it has closures and supports higher order functions.

Applets

An applet is a program written in the Java programming language that can be included in an HTML page, much in the same way an image is included in a page. When you use a Jave technology-enabled brower to view a page that contains an applets, the applet's code is transferred to your system and executed by the brower's Jave Virtual Machine (JVM). For information and examples on how to include an applet in an HTML page, refer to this description of the <APPLET> tag.

Blogs

A blog( a blend of the term web log) is a type of website or part of website. Blogs are usually maintained by an individual with regular entries of commentary, description of events, or other material such as graphics or video.
Entries are commonly displayed in reverse- chronological order. Blog can also be used as a verd, meaning to maintain or add content to a blog.

Wikis

A wiki is a website that allows the creation and editing of ant number of interlinked web pages via a web browser using a simplified markup language or a WYSIWYG text editor. Wikis are typically powered by wiki software and often used to create collaborative works. Examples include community websites, corporate intranets, knowledge management systems, and note services. The software can also used for personal notetaking.

FTP

File Transfer Protocol (FTP) is a standard network protocol used to copy a file from one host to another over a TCP- based network, such as the Internet. FTP is vuilt on a client-server architecture and utilizes separate control and data connections between the client and sever. FTP users may authenticate themselevs using a clear-text sign in protocol but can connect anonymously if the server is configured to allow it.

Plug-in

A plug-in (or plugin) is a set of software components that adds specific abilities to a larger software application. If supported, plug-ins enable customizing the functionally of an application. For example, plug-ins are commomly ysed in web browsers to play video, scan for viruses, and display new file types. well-known plug-ins examples include Adobe Flash Player and Quick Time.

Filters

In computing, filter(high-order function), a higher-order function that processes a data structure( typically a list) in some order to produce a new data structure for containing exactly those elements of the original data structure for which a given predicate returns the boolean value true.

Internet Security Suite

Internet Security Suite is available for Microsoft Windows. It offers anti-malware protection, a personal firewll and a Host-based intrusion Prevention System (HIPS) called Defense+ version 4.0 and later also includes a sandbox feature for isolating unknown applications.
