Difference between Laptop, Notebook, Netbook, Tablet PC and Ultrabook

We are running deep into the age of portable computers and right now they have almost replaced the conventional desktop computers in our daily lives. The need of portable computers was felt when people wanted to access their computers outside their homes. Eventually, the humans were more in need of “on the move” computing. A lot of portable computers have been introduced over time, capable of operating independent on location or surroundings. These devices usually came with internal batteries to keep them running irrespective of movement.
