hello friends, Today i am going to dicuse about what is blog, so we can say blog is place where we can share our thoughts, knowledge , exprience. in today time blog is best way to share knowledge and gain knowledge. By blogging you can also earn money, by displaying ads on your blog. SO blog is LIKE A WEBSITE but it is not hosted by you. although if you purchase your own domain name than you can host it yourself. to use blog you dosen't need to learn any programming language like html or java.
