iPhone
Definition:
The iPhone is a smart phone created by Apple that combines a mobile phone with an iPod. With an iPhone you can also browse the Internet, manage your email, manage your daily appointments, check stock prices, check the weather, watch YouTube videos and more. The iPhone looks different than a traditional mobile phone due to the fact that it relies on a touch-screen interface rather than traditional buttons.
Here's a word you may not know...
480p
The "480" part of 480p describes the number of vertical lines that make up a television or video signal. Most television or video signals are rated at 480, 720 or 1080. The more vertical lines that make up the picture, the crisper or higher definition the picture. The "p" following 480 indicates that the video display is constructed using a progressive scan method.
Many standard definition DVDs are published in a 480p format.
