Hardware Features of Apple's iPad

iPad tablets are tablet computers that run the iOS operating system, and they are designed, developed, and marketed by Apple Inc. The first iPads went on sale on April 3rd, 2010. The iOS operating system the iPad runs on is similar to the operating system used on Apple smartphones and laptop computers. The difference, however, is that the iPad combines the best features of a laptop or netbook with an iPod touch. In fact, Apple claims an iPad is the best way to experience the internet, email, videos, and photos. Unlike the Android tablet, Apple has strict control of the iPad from the design of the user interface (UI) all the way down to the hardware which houses the software.

The iPad boasts a list of impressive features, including an on-screen touch keyboard (similar to the iPhone and iPod touch), a built-in Bluetooth which works with the Apple wireless keyboard, an LCD-backlit multi-touch screen, and up to 10 hours of battery life. In addition, the iPad comes preloaded with Apple's iWork productivity suite of apps, optimized for the iPad. It's also very lightweight, weighing in at 1.5 pounds or less, depending on the type of iPad. All generations of iPads feature the following hardware components:

  • A processor
  • Memory chips
  • An internal storage chip
  • A battery
  • A sound processor and speakers
  • A graphics processor
  • Sensors, such as accelerometers, for touch screen capabilities
  • A Wi-Fi antenna
  • A camera
  • A Bluetooth chip

There have been five versions of the iPad to date. The first-generation iPad established the screen size for the full-sized iPads to follow. The second-generation iPad included a dual core Apple A5 processor and both front and rear-facing cameras, designed for FaceTime video calling. The third-generation iPad added a retina display, as well as an updated processor and camera. The fourth-generation iPad replaced the 30-pin connector with a Lightning connector. Finally, the fifth generation of iPad, the iPad Mini, featured a reduced screen size, and internal features similar to that of the iPad 2.

The iPad is typically used by three main industries: business, education and healthcare, and consumers. In regards to business, iPad penetrated 50% of Fortune 100 companies within 90 days of its release. iPads in the business environment are said to increase employee productivity, reduce paperwork, and even increase revenue. iPads are also widely used within the healthcare and education sectors. They are considered revolutionary tools in the classroom. In addition, iPads help hospitals manage their supply chain. Finally, the largest group of iPad users is clearly the consumer group. Consumers use iPads for just about anything.
