The image above shows a view of the first-generation iPad from the front, back, and side. Each side of the device has some features that are explained below. Knowing what the items are will help you get the most out of your iPad.
- Home button. You press this button when you want to exit an app and return to your home screen. It's also involved in restarting a frozen iPad and completing the process of rearranging your apps and adding new screens.
- Dock connector. This is where you plug in the including cable to sync your iPad and your computer.
- Speakers. The built-in speakers on the bottom of the iPad play music and audio from movies, games, and apps.
- Hold button. This button locks the iPad's screen and puts the device to sleep. It's also one of the buttons you hold to restart a frozen iPad.
- Antenna cover. This small strip of black plastic is found only on iPads that have 3G connectivity built in. The strip covers the 3G antenna and allows the 3G signal to reach the iPad. WiFi-only iPads don't have this; they have solid gray back panels.
- Mute Button. Like on the iPhone, toggling this switch will mute the volume of the iPad or restore it. On iPads running versions of the iOS prior to 4.2, this was the screen orientation lock, which prevented the iPad's screen from automatically switching from landscape to portrait mode (or vice versa) when you changed the orientation of the device.
- Volume Controls. Use this button to raise or lower the volume of the audio played through the speakers at the bottom of the iPad.
- Headphone Jack. - Plug in headphones here.
