Droid, or Android is the operating system of a line of mobile devices including phones and tablets. Android was developed by Google as a
direct competitor to the Apple iPhone and subsequent IPad. Android is based on the Linux operating system but has been heavily customized
to support features like voice recognition and phone dialing. Following the Droid philosophy, there are very few native applications built into
the operating system. Most functions such as web browsing and phone book are handled by external applications which run on top of the operating system.
A Development Kit is freely downloadable, allowing programmers to create their own applications. This is in stark contrast to Apple's controlled
development model, where every iPhone application must be reviewed by Apple prior to being made available on the Apple iTunes store.
In addition to software, Google has allowed dozens of manufacturers to sell hardware running the Android operating system, including Samsung, LG and others.
These phones and tablets are available from many retail electronics and phone stores.
