Modern tablets largely resemble modern smartphones, the only differences being that tablets are relatively larger than smartphones, with screens 7 inch or larger, measured diagonally, and may not support access to a cellular network.
Smartphones are typically pocket-sized, with somewhat larger sizes being called phablets; they are generally smaller than tablet computers.

Cellular network

cellular networkcellularmobile network
Modern tablets largely resemble modern smartphones, the only differences being that tablets are relatively larger than smartphones, with screens 7 inch or larger, measured diagonally, and may not support access to a cellular network.
This enables a large number of portable transceivers (e.g., mobile phones, tablets and laptops equipped with mobile broadband modems, pagers, etc.) to communicate with each other and with fixed transceivers and telephones anywhere in the network, via base stations, even if some of the transceivers are moving through more than one cell during transmission.

Pen computing

The tablet computer and its associated operating system began with the development of pen computing.
Pen computing is also used to refer to the usage of mobile devices such as tablet computers, PDAs and GPS receivers.

ARM architecture

ARMNEONARMv7
It used Apple's own new Newton OS, initially running on hardware manufactured by Motorola and incorporating an ARM CPU, that Apple had specifically co-developed with Acorn Computers. The devices were manufactured by several manufacturers, based on a mix of: x86, MIPS, ARM, and SuperH hardware.
These characteristics are desirable for light, portable, battery-powered devicesincluding smartphones, laptops and tablet computers, and other embedded systems.

Microsoft Tablet PC

Tablet PCTablet PCsspecifications
In 2002, Microsoft attempted to define the Microsoft Tablet PC as a mobile computer for field work in business, though their devices failed, mainly due to pricing and usability decisions that limited them to their original purpose - such as the existing devices being too heavy to be held with one hand for extended periods, and having legacy applications created for desktop interfaces and not well adapted to the slate format.
Hundreds of such tablet personal computers have come onto the market since then.

Virtual keyboard
