Today I learned many things that I never know before. I attended seminar on GitHub , Which is also known as Bitbucket. Actually these are websites that provides a facility to work in a team. In GitHub you can create your repository, In which you can store or upload your own project data. Multiple users can work on same project they can share data, can work at different module of same project. But for using this you have to install Git interface. In this anyone can use your source code and can keep changes in it. you can use Bitbucket from this website : https://bitbucket.org/.
And new thing, that I know today is remote access using openssh-server. Basically openssh-server provides remote access of another computer. But you must know IP address of another computer for remote access.
