<human>:  What is the difference between a laptop and a tablet?
<bot>: The main difference between a laptop and a tablet is that laptops are generally larger and heavier than tablets, have a physical keyboard and trackpad, and use an operating system such as Windows or Mac OS. Tablets are generally smaller and lighter than laptops, have a touch-screen and on-screen keyboard, and use an operating system designed specifically for mobile devices such as iOS or Android.
