It is not clear what question(s) you are asking. When you say, "Technology", you are not being very explicit. Almost anything could be called "Technology". As others have pointed out, it's a buzzword, like "World Class", or "Thinking Outside the Box" - or "Proactive", even. It's basically fluff.

DreamWeaver is a program that is used to build Web pages. I don't know if it's exactly an "IDE", but it does make Web development easier. It's a "Technology", but so is shipbuilding. The word, as I said, is without meaning. I wouldn't concern myself too much with trying to decide what's a technology and what's an IDE.

"Server side" describes where something happens. In a Web context, you have server side and client side. Either the client's browser or computer does something, or else the server (whatever s/he's connected to) does it.

The word "Process" has several meanings, depending on context. On a Windows box, if you type 'Ctrl-Alt-Delete', you will get the task manager, which can display the processes going on in your computer. Those processes often await certain conditions, and then do something. There is a process started by my antivirus program that will display a warning if a virus is detected.

In a Perl/CGI context, processes could be programs or sub-programs that respond to input, serve up pages, or perform any number of useful tasks.

My suggestion to you is to begin by deciding what it is you want to accomplish. If you are simply trying to learn Perl (or Perl/CGI web authoring), then you can find a wealth of information here using Super Search. There is also CPAN, where you can download Perl modules and find documentation for them.

If you are actively trying to create a CGI site, you probably need to learn considerably more than Perl - such as HTML, for one. You can Google for this information.

In any event, you have your work cut out for you. There is much to learn. You can find a great deal of help here at PerlMonks, but you'll still have to do your own sweating to learn Perl. It's not easy, but it certainly can be lots of fun - especially when there's a large community of helpful Monks to guide you along. Good luck.
