Intro to IT

JAVASCRIPT

JavaScript is a simple programming language that is often used to make the web pages more interesting. It was used to be called LiveScript, but was later changed to JavaScript as part of a marketing contract between Netscape and Sun. Although many think so, Java and JavaScript are actually two very different programs. For example, you do not need a Java-enabled browser to run JavaScript on a web page. JavaScript code was first invented to validate form fields. It warns users of any errors made before the form is submitted. Nowadays, JavaScript also run beyond web pages, such as through desktop widgets.


APPLETS

An applet is a small application that is written in a script language called Java. It is a program that can work on its own or through other applications. Standalone applets are usually small in size and call only perform a small set of task. Some examples are the Windows NotePad and Microsoft Paint. Applets that work as an extension to other applications must run in a container provided by the webhost, through a plug-in. Applets of this kind includes flash movies and browser games.


FILTERS

Filters are programs whose purpose is to block selected web sites, set time limits per use, monitor web page viewed on a certain computer or network, and create reports on use. In the case of internet safety among the younger audience, filters can help parents limit communication between their kids and other internet users, as well as the amount of time their kids can use the computer. Other than websites, filters can also block downloads and warn and block users from suspicious websites that could be fraudulent.


PLUG-INS

Plug-ins is a type of software components that enable specific tasks in a certain software program. It is commonly used in web browsers to play video, games, and other features. It can easily be installed and used as part of the browser as a plug-in application is recognized automatically by the browser and its function is integrated into the main HTML file that is being presented. Some of its advantages is that it minimize the size of the application, and enable third-party developers to create components to enhance a certain feature of the web browser.


INTERNET SECURITY SUITE

Internet security suite is a software that can be installed into a computer to protect it from various threats that could damage the internal data of the computer. It is usually packed with different kinds of security system like personal firewall, anti-spam, anti-pishing, parental controls, anti-virus and anti-spyware. It is affective in fighthing against virus, spyware, adware or keyloggers.





FTP (FILE TRANSFER PROTOCOL)

FTP or also known as File Transfer Protocol is an internet service which is used to upload and download files to be transferred between computers on a network, using TCP/IP protocols. It can be used to exchange files between different computer accounts, or even access online software archives. FTP can be used with a simple command line interface (for example, from the Windows MS-DOS Prompt window) or with a commercial program that offers a graphical user interface.


WIKI

Wikis are web pages that allow different users to contribute to the content of the page in addition to content itself through writing or editing. Wiki usually supports hyperlinks and simple text. Allowing everyday users to create and edit any page in a Web site is exciting in that it encourages democratic use of the Web and promotes content composition by nontechnical users. An example of Wiki pages are Wikipedia. A wiki farm is a collection of individual wikis, usually hosted by the same website.  The word wiki originated from Hawaiian bearing the meaning "fast".
