I have purchased a laptop of Toshiba since few weeks ago and I have connected an internet service provider of MTNL the MTNL is the leading internet service provider in Mumbai. I think so that it provides up to 4 Mbps of speed. And I think this is the fastest speed that I ever have. And I have windows 7 pre-installed in it. Recently I have made an account on the Facebook. And I am having the problem with the Facebook people and the problem is that what does the # symbol mean in the Facebook and why the people are using this symbol. Please help me in solving the problem. Thanking all in advanced for helping me and giving me the suggestions and your precious time.
