A tablet computer is a portable computing device that features a flat touch screen and is primarily operated by touching the screen. It is larger than a smartphone, yet smaller and more streamlined than a notebook computer. Tablets often use an onscreen virtual keyboard or a digital pen, rather than a physical keyboard. Many models incorporate handwriting recognition technology, converting handwritten input into editable text. The term “tablet” may also refer to a “convertible” notebook computer where a keyboard is attached to the screen via a swivel or slide joint, allowing for varied configurations.
Types of Tablet Computers
-
Slate Tablets Slate tablets are primarily touch-based and do not come with a built-in physical keyboard. They have become synonymous with modern tablets like the Apple iPad.
-
Convertible Tablets Convertible tablets have an attached keyboard that can be flipped or slid to lie underneath the touch screen. This allows users to switch between a traditional laptop mode and a touch-based tablet mode, seen in devices like the Microsoft Surface Book.
Historical Context

However, it wasn’t until Apple Inc. launched the iPad in 2010 that tablets gained widespread popularity and reshaped consumer electronics.
