A
tablet is a wireless, portable personal computer with a touch screen interface.
The tablet form factor is typically smaller than a notebook computer but larger
than a Smartphone.

digitize handwriting. Tablet PC's use digital ink technology.
A
tablet personal computer (PC) is a cross between a laptop or notebook computer
and a personal digital assistant (PDA). It's essentially a flat-panel portable
computer. The user either taps on the screen with his or her finger or with a
stylus, or he or she uses a stylus to write on the screen. A tablet PC can
wirelessly connect to the Internet and other computers. The term "tablet
PC" originally referred to a specific brand or tablets that were
compatible with certain operating systems, but any tablet-sized computer has
come to be referred to in some instances as a tablet PC.
The main feature of a tablet computer is portability. These devices typically are about the size of a thin book — roughly 7 to 8 inches (17.8 to 20.3 cm) wide by 9 to 10 inches (22.9 to 25.4 cm) tall and about 0.5 inches (1.27 cm) thick or less, although some might be slightly larger or smaller. They usually weigh less than 2 or 3 pounds (0.9 or 1.36 kg). Their size makes them convenient for businesspeople, students and just about anyone else to take with them in whatever they use to carry their belongings, such as a briefcase, backpack or purse.

Some
tablet PCs come with detachable keyboards that allow them to function like
laptop computers. Others have separate keyboards that are accessory items,
rather than part of the normal device. There are even models that have the clam shell design of a typical laptop, with a literal twist — the screen can
rotate 180 degrees and can be closed with the screen-side up so that the
tablet PC can continue to be used without the keyboard. A
tablet PC can be used for many purposes, including business, education and
entertainment. Many of these devices use the same operating systems as desktop
or laptop computers and can be connected to them for things such as managing
content and transferring files. Some tablet computers allow their users to
download special applications that work only on specific brands or types of
devices. Most are able to connect to the Internet using wireless technology,
and some are able to do so through cellular phone communication technology,
thereby giving their users Internet access in a much wider area.
A
tablet PC is manufactured by assembling multiple hardware components. Many of
the components are same as those you find in a regular desktop computer or
laptop. Other distinguishing components are mentioned below:
Unlike regular computers, the key usage of tablet PC is ease of convenience while on the move. That is, mobility becomes an important factor while choosing or purchasing a tablet PC. Almost
all tablet PCs come with touch screen enabled display. This makes it easy for
an end-user to conveniently interact with the tablet. Many manufacturers also
provide a stylus, which is a touch tool for interaction with touch screens.
Every touch screen has a gesture or touch controller microchip which helps
detect and process the touch interactions from the end-user. Accelerator meter
is a component that helps determine motions and movements in a tablet PC. This
feature is widely used while playing games and in entertainment apps. Gyroscope
is another such component which determines the orientation of a tablet display.
That is, the display layout can change according to how you hold a tablet PC –
vertically or horizontally. Graphics processor helps run graphic-intensive apps and games. It renders high definition pixels on the display. Network
connectivity comes into picture when you talk of mobility. A user should be
able to connect to the Internet via different types of networks depending on
its availability. Wi-FI, GSM, LTE, CDMA and others are types of network
connectivity. Tablet
PCs can be plugged into a power source or can also run on recharged battery.
This feature particularly helps in using it while on the move. GPS
system helps you determine your location on apps like Google Maps. It is also
used in apps that help navigate through cities and countries. There
are several types of Tablet PCs and various models have different functions in
order to fulfill the needs of different types of computer users. For instance,
a businessman who uses a tablet PC may be interested in different functions and
accessibility than someone who just wants a computer that they can use in bed.
Tablet PCs include “booklet”, “slate”, “convertible”, and “hybrid” models. As
technology gets better over the next year or so, there will undoubtedly be even
more models of tablet PCs to choose from. Booklet
A booklet tablet PC is a device that folds open like a book and has a screen on either side. Booklet tablet PCs are equipped with touch screen functionality in both screens and comes with a stylus pen for additional support. This type of computer, as do many tablet PC models, has pen writing recognition software that allows you to actually write on your screen as if you were writing on paper and the computer will process it as computer text. Booklet PCs allow you to fold the device up and take it with and then unfold it to plan your schedules and projects, get on the Internet, play music and other media, read books, and even display a separate application on each screen for dual-monitor use. Slate
With a slate tablet PC, it is like you are carrying around a small flat screen TV as a computer. Slate computers do not have a keyboard and instead require the user to depend on the touch screen or a stylus pen to enter text and perform functions. Of course, if you would rather have a keyboard, you can setup a wireless one or plug one in via USB port. Since the amount of moving parts has been decreased with the lack of a keyboard, slate tablet PCs are typically notably more resilient and can often be much smaller than other types of tablet PCs. The iPad is the most prominent example of a slate type of tablet. Convertible
Convertible tablet PCs are a popular option for users that wish to retain the option of keeping their keyboard functionality while taking advantage of the convenience of the touch screen technology. Convertibles look almost identical to a traditional laptop when the lid is shut, however when the lid is opened, an innovative swiveling hinge allows the screen to turn a full 180 degrees, allowing the casing of the laptop to lie back against the keyboard. This allows the user to view the screen and interact with the laptop much as if it were a traditional paper notebook. Hybrid
Hybrid
tablet PCs combines the best of both worlds by joining slate technology with
the functions of a convertible. With a hybrid tablet PC, you can either use the
monitor alone as a slate computer or attach a keyboard to it and have the
monitor swivel around like a convertible. Hybrid tablet PCs come with both
monitor and keyboard and simply allow you to detach the devices from each other
whenever you want. The stylus pen and touch screen functions are also included
in this model

Design Considerations A
Tablet is a handheld electronic device primarily designed to run multimedia and
web-based applications which require considerable processing power. Its main
advantage over a laptop PC or a Notebook PC is its portability which is
achieved by having a small form factor and less number of peripheral devices.
Additionally, it uses a touch screen as the primary interface to control and
interact with the product. Key requirements for a Tablet include: |
