2. How ActiveX Works
ActiveX is a Microsoft created
technology that enables different
software applications to share
information and functionality.
ActiveX only works with Microsoft
applications like Word, Excel,
Internet Explorer and PowerPoint,
and will only work on a computer
running the Windows operating
system.
3. How JavaScript Works
JavaScript is what is called a
Client-side Scripting Language.
That means that it is a computer
programming language that runs
inside an Internet browser (a
browser is also known as a Web
client because it connects to a
Web server to download pages).
4. How Java Works
All of the tools you need to start
programming in Java are widely
available on the Web for free. There is
also a huge amount of educational
material for Java available on the Web,
so once you finish this article you can
easily go learn more to advance your
skills. You can learn Java programming
here without spending any money on
compilers, development environments,
reading materials, etc. Once you learn
Java it is easy to learn other languages,
so this is a good place to start.
5. How CGI Scripting Work
On most Web servers, the CGI mechanism has
been standardized in the following way. In the
normal directory tree that the server considers to
be the root, you create a subdirectory named cgi-
bin. (You can see this directory in the figure on
the previous page.) The server then understands
that any file requested from the special cgi-bin
directory should not simply be read and sent, but
instead should be executed. The output of the
executed program is what it actually sent to the
browser that requested the page. The executable
is generally either a pure executable, like the
output of a C compiler, or it is a PERL script.
PERL is an extremely popular language for CGI
scripting.
