Website blocking without third party applications

how to block a particular website without any software
Today i am telling to how to block a particular website like facebook,google etc...

This  method is used to block some websites in our schools and collages. Also this same method is used to unlock the website.
Let me remind you that this method is appropriate when we are not able to edit the internet options settings manually without admin privileges.

Step 1: Make sure about the website that you really want to block  and also you have to know the  name of that website like"www.google.com"

Step 2: Now you have to open your System Drive in your computer

Step 3: If Your OS is in drive C:\ then Go to this Path in your compu ter "C:\Windows\System32\drivers\etc\"

Step 4: There is a file named "hosts" Open this file in your text editor (You can use your favorite one 'Notepad' )

after a localhost add your link which you want to block with the same IP address

Step 5:
Now Save this file in Any Other place and replace with the original one.

Step 6:
Now you can see that google is blocked in your computer so, you are not able to access google .Ya Don't Forget to close all the Folders Which is Open in your Explorer
