Describe the different types of tablets. What is a stylus?

Usually smaller than a laptop but larger than a smartphone, a tablet is a thin, lightweight mobile computer that has a touch screen. Two popular form factors of the tablet are the slate and convertible. Resembling a letter-sized pad, a slate tablet is a type of tablet that does not contain a physical keyboard. A convertible tablet is a tablet that has a screen it its lid and a keyboard in its base, with the lid and base connected by a swivel-type hinge. You can use a convertible tablet like a traditional laptop, or you can rotate the display and fold it down over the keyboard so that it looks like a slate tablet. As with laptops, tablets run on batteries or a power supply or both; however, batteries in a tablet typically last longer than those in laptops. 

Some tablets include a stylus, which looks like a small ink pen, that you can use instead of a fingertip to enter data, make selections, or draw on a touch screen. A stylus may include buttons you can press to simulate clicking a mouse. As an alternative to interacting with the touch screen, some users prefer to purchase a separate physical keyboard that attaches to or wirelessly communicates with the tablet.
