Java vs. JavaScript
Java was introduced by Sun Microsystems in 1995. The programming language designed for use in the distributed environment of the Internet (TechTarget). Although it was designed to have the "look and feel" of the C++ language, it offers greater ease of use and enforces an object-oriented programming model. Programmers can use Java to create complete applications that may run on a single computer or be distributed among servers and clients in a network. Programmers can also use Java to build a small application module or applet for use as part of a Web page. Applets make it possible for a Web page user to interact with the page.
JavaScript is an interpreted programming or script language created by Netscape to integrate the functionality of Java with HTML (TechTarget). It is similar in capability to Microsoft's Visual Basic, Sun's Tcl, the UNIX-derived Perl, and IBM's Rexx. Script languages are easier and faster to code in than the more structured and compiled languages such as C++ and Java. However, Script languages generally take longer to process than compiled languages and therefore, are more useful for shorter programs. JavaScript is typically used in Web site development to do such things as automatically changing a formatted date on a Web page, causing a linked-to page to appear in a popup window and causing text or a graphic image to change during a mouse rollover.
A programmer can write fully-functional JavaScript using a simple text editor....
How will JavaScript Technology change my life The best benefit of all of learning JavaScript, its syntax, integration with XML and AJAX is the how marketable this skill is today. Being able to define which rich client is best for a given need is an essential skill going forward in any programming or technical career (Zeichick, 2008). JavaScript will hopefully give me an opportunity to earn more money over time. What are
Asynchronous JAVA Script & XML (AJAX) Asynchronous JavaScript and XML (AJAX) are set of technologies with different function that work together to allow the client-server to create a rich web application (Deursen & Mesbah, 2009). The purpose of this paper is to describe more about AJAX, how is it used to create a web application, the difference from classical web application, companies utilizing this technique, security issues, and how to migrate
(Hackers Chronology, 2006). 1989 The first case of cyber espionage is recognized in Germany (west). This reportedly involved the CHAOS computer club. "Mentor releases the hacker manifesto Conscience of a hacker, which ends with the intriguing line: 'You may stop the individual, but you can't stop us all.'" (Hackers Chronology, 2006). 1990 Electronic Frontier, Freedom on the Internet advocacy group, is launched Polymorphic viruses (which modifies themselves when they spread), along with other sophisticated kinds of
Internet Explorer and Netscape Browsers Most people in 2005 have accessed the World Wide Web, and chances are, they used Microsoft Internet Explorer to do it. In 1995, the situation was quite different; far fewer people had accessed the Web, and most of those who had used Netscape Navigator. Microsoft saw Netscape and the Web as a competitive threat to its operating system business, and launched its own browser to
The responsibility to seek out and use the most appropriate form of protection for a particular system lies with its user. If a user does not regard these duties with the appropriate seriousness, the consequences could be dire indeed. Another very threatening form of computer crime is the phishing scam. Phishing Phishing involves email from an apparently legitimate source such as a bank or other place of business that requires the user
82). Both desktop and Web widgets have the same basic components. Fundamentally, they use Web compatible formats, even if intended to run in a desktop environment. This means that the core of the widget is HTML and CSS code which contains the actual content of the widget, namely text, linked images/video or content pulled from a server of Web service. Alternatively, the widget content can be created using Flash, although
