Free Software is software that is available free of charge and is an open source that one has the freedom to make changes.There are free operating systems available such as ubuntu.com and gnu.org.There are many free software programmes a very popular one in our home is You Tube.com this is a very entertaining site for veiwing videos. Some others I learnt about today are TED.com showing talks, discussions and demonstrations,vimeo more video clips , submedia.t.v blogging site for video clips and another that I already know about is the extremly helpful Wikipedia having alot of information available .
