What Java is
Developed by Sun Microsystems, it is a programming language specifically designed for writing programs that can be safely downloaded through the Internet without fear of viruses or other harm to computers or files. Using small Java programs called applets, Web pages can include functions such as animations, calculators, and other fancy tricks. Java is a simple, robust, object-oriented, platform-independent, multi-threaded, dynamic, general-purpose programming environment. It is best used for creating applets and applications for intranets, the Internet, and any other complex, distributed network.
The meaning of Browser
A program used to view, download, upload, surf, or otherwise access documents (for example, Web pages) on the Internet. Netscape Navigator and Internet Explorer are well-known "Web browsers" that enable you to view and interact with Web sites.
Browsers read pages that are "marked up" or coded (usually in HTML but not always). These pages reside on servers. The browsers interpret the code into what we see rendered as a Web page. As well-designed software programs, browsers contain a variety of tools, including bookmarks and the back button, that make "surfing the Net" more enjoyable. You will need a browser to "get on the Web." Visit this definition on NetLingo.com for a link to product reviews and free downloads.
