Tablets are mobile computers that are very handy to use. They use the touch screen
technology. Tablets come with an onscreen keyboard or use a stylus or a digital pen. Apple‘s iPod
redefined the class of tablet computers.
Tablet PCs offer all the functionality of a notebook PC
, but they
are lighter and can accept input from a
special pen—called a stylus or a digital pen—that is used to tap or write directly
on the screen.

A tablet is a wireless, portable personal computer with a touchscreen interface. The tablet form factor is typically smaller than a notebook computer, but larger than a smartphone. The idea of tablet computing is generally credited to Alan Kay of Xerox, who sketched out the idea in 1971.
Tablet PCs also have a built-in microphone and special software that accepts input from the user's voice. A few models even have a fold-out
keyboard, so they can be transformed into a standard
notebook PC. Tablet PCs run specialized versions of
standard programs and can be connected to a network. Some models also can be connected to a
keyboard and a full-size monitor.
