This was something that I almost forgot to mention – sometime ago one of my former students had mentioned to me about the importance of YouTube – what he told me is that you could get most of the study methods or videos regarding technical or configuration of servers or routers from YouTube. Most of this are pretty good – these are uploaded by various people. So you could watch this online or download from YouTube. This is of big help to everyone. Its time you shifted watching pron videos online and watch these tech videos instead..
