Concept of URL
URL means Uniform Resource Locator.
Two types of URL
a) Relative URL – Here we explicitly give the web site address

b) Absolute URL – Here we implicitly give the website address. The path is not specified here.
Eg: Consider the web pages index.html and school.html saved in the folder C:\BVM.
The file indexs.html contains the following.
<A href=”school.html”>.

Here we did not specify the full path of the file school.html. But this implicitly points to the file stored in C:\BVM
