OpenAL Short for Open Audio Library, it is an audio API that can process multichannel three-dimensional audio.
OpenGL ES OpenGL for Embedded Systems is a mobile optimized version of the OpenGL 3D graphics API.
OS The iPhone OS stands for the iPhone Operating System. Developers create iPhone applications that are run on top of the iPhone OS. The iPhone OS is made up of many other software libraries, APIs, and applications.
peer-to-peer (P2P) Describes a network situation where two or more systems connect and share responsibilities. Unlike client server connections, a peer in a peer-to-peer configuration will at times act as both client and server. In the iPhone SDK, peer-to-peer is a popular choice for connecting nearby devices over Bluetooth.
PNG A PNG or portable network graphics format file is an image file with an 8-bit transparency alpha channel. It is the native image format of the iPhone SDK.
Quartz When you hear Quartz as it relates to the iPhone, always think graphics. Quartz is the primary 2-D graphics-rendering library for the iPhone—and for Mac OS, for that matter.
SDK The iPhone SDK stands for the iPhone Software Development Kit. Developers can use the iPhone SDK to create applications for the iPhone.
Simulator The iPhone Simulator lets you build and run your iPhone applications on your computer without using a real device. One advantage of the Simulator is that even registered developers can use it. You do not have to be a paid developer to utilize the Simulator.
sprite The general term for an image or graphic object. Sprites are very common in game programming circles.
SQLite SQLite is the database of choice for iPhone applications. It is small, powerful, and free. Support for SQLite is included in Core Data.
Status Bar The iPhone Status Bar contains the icons located at the top of the screen, which give information about the iPhone's current status. Common status information includes Wi-Fi and cellular connectivity. It can also include Bluetooth and remaining battery status.
transparency Transparent objects are clear and can be seen through. Transparent and opaque are opposites of each other. Many objects in the iPhone SDK, such as the UIImageView, support transparency.
UDID The UDID is the unique device identifier for an iPhone or iPod touch.
UIAlertView A UIAlertView is used to show the user a standardized view containing alert information. It operates as a message box and allows the end user to acknowledge and respond appropriately.
UIButton The UIButton class is a UIControl that creates a button on the screen. A button can receive and respond to touch events. You can set the title, image, and other properties of the button. You can also assign a separate appearance for each button state.
UIColor A UIColor object is used throughout the iPhone SDK to represent color information. It can be used to assign colors to UI elements both at design time and run-time.
UIDevice The UIDevice class represents the current device. From this object you can get information about the device, such as unique ID, assigned name, device model, and operating system name and version.
UIImage A UIImage object is a high-level way to display image data. You can create images from files, from Quartz image objects, or from raw image data you receive. The UIImage class also offers several options for drawing images to the current graphics context using different blend modes and opacity values.
UIImageView A UIImageView object can display either a single image or an animation of a series of images. You can set the frequency and the duration of the animation, and you can start and stop the animation as needed.
UILabel The UILabel class creates a read-only text view. You can also use this class to draw either one or multiple lines of text. You have options to modify the appearance of your text as well.
UINavigationBar The UINavigationBar is used for navigating up and down through hierarchical content. The UINavigationBar is usually shown at the top
