A petabyte (derived from the SI prefix peta- ) is a unit of information equal to one quadrillion (short scale) bytes, or 1000 terabytes. The unit symbol for the petabyte is PB. The prefix peta (P) indicates the fifth power to 1000:

• 1 PB = 1000000000000000B = 1000⁵ B = 10¹⁵ B = 1 million gigabytes = 1 thousand terabytes

The Motorola Droid (stylized as DROID; GSM/UMTS version: Motorola Milestone) is an Internet and multimedia enabled smartphone designed by Motorola, which runs Google's Android operating system. The Droid had been publicized under the codenames Sholes and Tao and the model number A855. In Latin America and Europe, the model number is A853 (Milestone), and in Mexico, the model number is A854 (Motoroi). Due to the ambiguity with newer phones with similar names, it is also commonly known as the DROID 1 or the OG DROID (where OG is short for OriGinal or Original Gangster or Old school Gangster). The brand name Droid is a trademark of Lucasfilm licensed to Verizon Wireless.
Features of the phone include Wi-Fi networking, a 5-megapixel low light capable digital camera, a standard 3.5 mm headphone jack, interchangeable battery, 3.7-inch 854 x 480 touchscreen display. It also includes microSDHC support with bundled 16 GB card, free turn-by-turn navigation from Google Maps, sliding QWERTY keyboard, and Texas Instruments OMAP 3430 processor. The Motorola Droid runs Android version 2.2.
The phone does not, however, run the re-branded Motoblur interface for Android, instead providing the Google Experience skin and application stack.
The Droid has a hearing aid compatibility (hac) rating of M3/T3. The phone was the first to ship with free Google Maps Navigation (beta) installed.

Google Chrome OS is a Linux-based operating system designed by Google to work exclusively with web applications. Google announced the operating system on July 7, 2009 and made it an open source project, called Chromium OS, that November.
Unlike Chromium OS, which can be compiled from the downloaded source code, Chrome OS only ships on specific hardware from Google's manufacturing partners. The user interface takes a minimalist approach, resembling that of the Chrome web browser. Since Google Chrome OS is aimed at users who spend most of their computer time on the Internet, the only application on the device is a browser incorporating a media player and a file manager.
The expected launch date for retail hardware featuring Chrome OS slipped after Google first announced the operating system: from an initial forecast date in late 2010 to June 15, 2011, when "Chromebooks" from Samsung (and then Acer in July) actually shipped.

An operating system (OS) is a set of programs that manage computer hardware resources and provide common services for application software. The operating system is the most important type of system software in a computer system. A user cannot run an application program on the computer without an operating system, unless the application program is self booting.
Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting for cost allocation of processor time, mass storage, printing, and other resources.
For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between application programs and the computer hardware, although the application code is usually executed directly by the hardware and will frequently call the OS or be interrupted by it. Operating systems are found on almost any device that contains a computer—from cellular phones and video game consoles to supercomputers and web servers.

Android is an operating system for mobile devices such as smartphones and tablet computers. It is developed by the Open Handset Alliance led by Google.
Google purchased the initial developer of the software, Android Inc., in 2005. The unveiling of the Android distribution on November 5, 2007 was announced with the founding of the Open Handset Alliance, a consortium of 84 hardware, software, and telecommunication companies devoted to advancing open standards for mobile devices. Google released most of the Android code under the Apache License, a free software license. The Android Open Source Project (AOSP) is tasked with the maintenance and further development of Android.
Android consists of a kernel based on the Linux kernel, with middleware, libraries and APIs written in C and application software running on an application framework which includes Java-compatible libraries based on Apache Harmony. Android uses the Dalvik virtual machine with just-in-time compilation to run Dalvik dex-code (Dalvik Executable), which is usually translated from Java bytecode.
Android has a large community of developers writing applications ("apps") that extend the functionality of the devices. Developers write primarily in a customized version of Java. There are currently approximately 300,000 apps available for Android, from a total of 500,000 apps over the life of Android. Apps can be downloaded from third-party sites or through online stores such as Android Market, the app store run by Google.
Android was listed as the best-selling smartphone platform worldwide in Q4 2010 by Canalys with over 200 million Android devices in use by November 2011.
