You might have stared preparing for your Lab internal exams. Here I give you the lab programs written by me in Web designing. This will help you in case you are not finding all of them at one place. I'm not sure with the output of 5(b). Please verify whether it is the required output or not.
Unzip the file and copy the entire folder in the root directory of your web server. If you have installed XAMPP, then the root directory is C:\xampp\htdocs. The best way to learn web designing is to make changes in the code and learn its effects.
One important thing. For typing these programs I highly recommend you to use Notepad++. This is a special editor especially for programmers. If you don't have it, then you can download it for free at http://download.cnet.com/Notepad/3000-2352_4-10327521.html. You can also use other softwares such as Aptana Studio. For Aptana Studio you need to have Java runtime installed on you system. You can download Java runtime for free if you don't have it. You can also use Microsoft Expression Web.
I am aware that you need lab programs in Computer Networks also. Don't worry I'll be posting it very soon. Till then, hope this helps.
