NOTES

What is a WebPage?

A Webpage is a document that resides on a remote computer site.  That side could be anywhere in the world, yet when we 'browse' the internet.  In fact, in e-mail program's Preferences set to messages in HTML format(if using Outlook Express or Netscape 6, this will probably have been done automatically), then the mini webpages is created every time when tap in new message and send it.

HTML- HyperText Markup Language- is the code that underpins webpages.  In this day and age, there are too many software application out there that take care of all the HTML; we just need to concentrate on the design and content .
The software tools that do this are called WYSIWYGs, which stand for 'What You See Is What You Get'.  Means that you can see how your webpage looks as you create it - and there is also a bunch of user-friendly tools to enable you to amend text and graphics to an almost infinite degree.

Web Browsers

A web browser is that we use to view the Internet Explorer and Netscape Navigator (or Communitor).  A browser is the software which will use to view the webpages at a particular Internet address (or URL), and the should open automatically wheneverwe doubleclick a webpage, or HTML file, on the desktop.

Which Web Design Software?

To build a website, HTML pages has to been created.  We could still do this by learning HTML code and writing it directly into Notepad, Simple Text or something similar.  There are plenty of applications available today in which we can design our pages visually, in just the we would a newsletter in Microsoft Word which they will write all the HTML.
Web design software ranges from the most basic, entry-level packages such as FrontPage Express and Netscape Composer, to more professional composer such as Dreamweaver and Adobe GoLive.


Java

A high level programming language developed by Sun Microsystems. Java was originally called OAK, and was designed for handheld devices and set-top boxes. Oak was unsuccessful so in 1995 Sun changed the name to Java and modified the language to take advantage of the burgeoning World Wide Web.

Java is an object-oriented language similar to C++, but simplified to eliminate language features that cause common programming errors.  Java source code files (files with a .java extension) are compiled into a format calledbytecode (files with a .class extension), which can then be executed by a Java interpreter. Compiled Java code can run on most computers because Java interpreters and runtime environments, known as Java Virtual Machines (VMs), exist for most operating systems, including UNIX, the Macintosh OS, and Windows. By thecode can also be converted directly into machine language instructions by a just-in-time compiler(JIT).

Java is a general purpose programming language with a number of features that make the language well suited for use on the World Wide Web. Small Java applications are called Java applets and can be downloaded from a Web server and run on your computer by a Java-compatible Web Browser, such as Netscape Navigator or Microsoft Internet Explorer.

Streaming

Streaming or media streaming is a technique for transferring data so that it can be processed as a steady and continuous stream. Streaming technologies are becoming increasingly important with the growth of the Internet because most users do not have fast enough access to download large multimedia files quickly. With streaming, the client browser or plug-in can start displaying the data before the entire file has been transmitted.

For streaming to work, the client side receiving the data must be able to collect the data and send it as a steady stream to the application that is processing the data and converting it to sound or pictures. This means that if the streaming client receives the data more quickly than required, it needs to save the excess data in a buffer. If the data doesn't come quickly enough, however, the presentation of the data will not be smooth.

There are a number of competing streaming technologies emerging. For audio data on the Internet, the de facto standard is Progressive Network's RealAudio.

Linux

Pronounced lee-nucks or lih-nucks. A freely-distributable open source operating system that runs on a number of hardware platforms. The Linux kernel was developed mainly by Linus Torvalds and it is based on Unix. Because it's free, and because it runs on many platforms, including PCs and Macintosh, Linux has become an extremely popular alternative to proprietary operating systems.
