4.How it is different from
a smart phone or a cell phone
Like laptops, tablet computers are designed to be portable.
However, they provide a very different computing experience.
The most obvious difference is that tablet computers don't
have keyboards or touch pads. Instead, the entire screen
is touch-sensitive, allowing you to type on a virtual keyboard
and use your finger as a mouse pointer. Tablet computers
are mostly designed for consumers, and they are optimized
for tasks like web browsing, watching videos, reading e-books,
watching photos, and playing games. For many people, a "regular"
computer like a desktop or laptop is still needed in order
to use programs like Microsoft Word or Photoshop. However,
the convenience of a tablet computer means that it may be
ideal as a second computer. Below are some of the main features
that you can expect with a tablet computer.
Tablet computers usually use solid-state drives, which
allow the computer to boot up and open programs more quickly.
They are also more durable than hard disk drives.
Wi-Fi and 3G/4G: Since they are optimized for Internet
use, tablet computers have built-in Wi-Fi. For a monthly
fee, you can also purchase a 3G or 4G data plan, allowing
you to access the Internet from almost anywhere.
In order to save space, tablet computers have very few
ports. If you want to use an external keyboard or other
peripherals, they will often use a wireless Bluetooth connection
In comparison, a smart phone is a powerful mobile phone
that is designed to run a variety of applications in addition
to phone service. They are basically small tablet computers,
and they can be used for web browsing, watching videos,
reading e-books, playing games and more. Smart phones use
touch screens and operating systems similar to those used
by tablet computers. Many of them use a virtual keyboard,
but others (such as the BlackBerry Curve) have a physical
keyboard, which allows the entire screen to be used for
display purposes. Internet access is an important feature
of smart phones. Generally, you will need to purchase a
3G data plan in addition to normal cell service. Smart phones
can also connect to Wi-Fi when it is available, which is
usually faster than 3G. The differences between smart phones
and a tablet PC are very few, such as larger screen area,
extended battery life, higher computing power and memory
capacity in tablet PCs.
