I think the best amazing website on the world network is youtube.com. Because there is a lots of videos are uploaded daily. that means a lots of information. about the world.
It is the power of social network. For student purpose, it is best to use. there is a lots of video tutorials for various subjects and technologies. For example, before six months I did not get the jobs in any it industry. But after learning the basics and advance concept of programming from youtube.com. Now I get the jobs reputed company webkul software pvt ltd, Noida.
I observe that this is only site where every type of information is available.yes, there are worst aspects for youtube.com. there is a lots of advertisement displaying on the website that consuming a lots of data and time. But its benefits overcome its worst aspects.
