Mobile <strong>Computing</strong><br />

The predecessor of tablets was <strong>the</strong> laptop or<br />

portable computer. As opposed to previous<br />

desktop computers, laptops were powered by<br />

mobile power sources such as large lithium<br />

batteries allowing computers to be carried<br />

away from a wall socket. The processor and<br />

hard-drive were also connected directly with<br />

<strong>the</strong> monitor, creating a component that could<br />

be carried around easily with little additional<br />

pieces o<strong>the</strong>r than perhaps a mouse or<br />

additional keyboard.<br />

Laptops eventually began to offer many of <strong>the</strong><br />

same capabilities as desktop computers.<br />

However, <strong>the</strong>y did not offer any significant new<br />

functionality from regular desktop computers.<br />

Mobility: <strong>Tablet</strong>s were designed with high<br />

mobility in mind. They are smaller than most<br />

laptops while being larger than a phone. Unlike<br />

use while still offering readability with a large<br />

screen. Unlike cell phones, tablets are<br />

generally more powerful and offer much more<br />

features.
