3. Mobile Devices

3.1 Explain the basic features of mobile operating systems

1. Advanced Configuration and Power Interface (ACPI) specification provides an open standard for device configuration and power management by the operating system.

2. The specification is central to Operating System-directed configuration and Power Management (OSPM), a system implementing ACPI, which removes device management responsibilities from legacy firmware interfaces.

3. The Advanced Host Controller Interface (AHCI) is a technical standard defined by Intel that specifies the operation of Serial ATA (SATA) host bus adapters in a non-implementation-specific manner.

4. iOS 5 offers untethered updates.

5. You can see the IP address of an iOS device by going to Settings > General > Network > Wi-Fi > SSID Name > IP address

6. iTunes is a media player and media library application developed by Apple Inc. It is used to play, download, and organize digital audio and video on personal computers running the OS X operating system and the iOS-based iPod, iPhone, and iPad devices, with editions also released for Microsoft Windows.

7. iCloud is a cloud storage and cloud computing service from Apple Inc. The service allows users to store data such as music and iOS applications on remote computer servers for download to multiple devices such as iOS-based devices running iOS 5 or later, and personal computers running OS X 10.7.2 "Lion" or later, or Microsoft Windows (Windows Vista service pack 2 or later).

8. Gyroscope enables re-alignment of screen orientation as the user turns his phone.

9. The Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. Most smart phones have GPS built in to the software.

3.2 Establish basic network connectivity and configure email

1. Bluetooth is widely used for communication between smart phones and other accessories or between PDAs and information kiosks. The typical coverage for Bluetooth devices is up to 30 feet.Bluetooth devices, when in discoverable mode, are able to be seen ( discovered ) by other bluetooth devices. If two phones connect, the phone that is trying to establish the initial connection, must be looking for a phone that is "discoverable" otherwise it will not see it. Once the connection is saved, discoverable mode is no longer necessary, as the phones already know each other. This is only necessary during an initial link.

2. The Wireless function key typically turns on / off the wireless radio. If you inadvertantly press the function key, it is possible that you are not able to access the Internet, if using WiFi.

3. You need to know your domain name (e.g. example.com.au), email address (e.g. yourname@example.com.au) and email account password. You also need to know the POP or IMAP server name.
