Now almost everything is virtual.  In the office we already have what we call virtual Information Technology where all the information technology employees from all the affiliates of one company are merged into one.  So even if they belong to different sets of companies, they also belong to one Information Technology, although no physical office to speak of yet.  That is why it is called Virtual IT.

Same thing with Virtual Telephone, you do not see an actual telephone but you can make use of it to call a love one or a friend or even somebody whom you do not know.
