Hi Annu_Shah
Unlike the Arduino Yun, the Galileo doesn't have a web server running by default.
As CMata mentioned you can create a web server using one of the programming languages - Node.js or Python, or you can install a web server.
I outlined how you can install Flask, a Python based web server here

Since it is written in Python you can use the Wiring_x86 library from EmuTek and display information from sensors, pictures taken with a web cam and control the GPIO pins. See the example for WebLamp
