The iPad is a tablet computer designed and developed by Apple. It is particularly marketed for consumption of media such as books and periodicals, movies, music, and games, and for general web and e-mail access. At around 700 grams its size and weight are intermediate between most contemporary smartphones and laptop computers. Sales of the iPad tablet are strong.
Apple is best known for the hardware products which includes mac computers ,iphone the ipod and now another revolutionary product called the Ipad. It is particularly marketed as a platform for audio and visual media such as books, periodicals, movies, music, and games as well as web content. It has been designed to fill the illusive gap between the notebooks and the smartphones. It has got the features of both the laptops and the iphone . Like iPhone and iPod Touch, the iPad is controlled by a multitouch display — a break from most previous tablet computers, which used a pressure-triggered stylus. All of the built-in apps on iPad were designed from the ground up to take advantage of the large Multi-Touch screen and advanced capabilities of iPad. And they work in any orientation. So you can do things with these apps that you can’t do on any other device. Its hard to believe how something so thin and light can be so capable.
Power And Battery
The iPad uses an internal rechargeable lithium-ion polymer battery. The batteries are made in Taiwan by Simplo Technology, which makes 60% of them, and Dynapack International Technology. The iPad is designed to be charged with a high current (2 amperes) using the included USB 10 W power adapter. While it can be charged by a standard USB port from a computer, these are limited to 500 milliamperes (half an amp). As a result, if the iPad is turned on while being charged with a normal USB computer port, it will charge much more slowly, if at all.
The iPad can use Wi-Fi network trilateration from Skyhook Wireless to provide location information to applications such as Google Maps. The3G model contains A-GPS to allow its position to be calculated with GPS or relative to nearby cellphone towers; it also has a black plastic accent on the back side to improve 3G radio sensitivity For wired connectivity, the iPad has a dock connector; it lacks the Ethernet and USB ports of larger computers.
Like the iPhone, with which it shares a development environment (iPhone SDK, or software development kit, version 3.2 onwards), the iPad only runs its own software, software downloaded from Apple's App Store, and software written by developers who have paid for a developer's license on registered devices.The iPad runs almost all thirdparty iPhone applications, displaying them at iPhone size or enlarging them to fill the iPad's screen. Developers may also create or modify apps to take advantage of the iPad's features. Application developers use iPhone SDK for developing applications for iPad.

The Ipad And The Ipod Touch
The iPad runs iPhone OS. It will use many of the same APIs to write your iPad apps that we use to write apps for the iPhone. So isn’t the iPad just a big iPod touch? It’s certainly true that an iPad is much bigger than an iPhone. An iPad is about the size of the printed version of this book—about half an inch taller and a little thinner, but roughly the same size. The iPhone is much smaller. Here’s a picture that shows the relative size of two iPhone screens to the iPad screen. So the iPad is a big iPod touch—it’s just not just a big iPod touch. Being bigger is the key to what makes it special.
