Android (operating System)
Android is a mobile operating system based on a modified version of the Linux kernel and other open-source software, designed primarily for touchscreen mobile devices such as smartphones and tablets. Android is developed by a consortium of developers known as the Open Handset Alliance and commercially sponsored by Google. It was unveiled in November 2007, with the first commercial Android device, the HTC Dream, being launched in September 2008. Most versions of Android are proprietary. The core components are taken from the Android Open Source Project (AOSP), which is free and open-source software (FOSS) primarily licensed under the Apache License. When Android is installed on devices, the ability to modify the otherwise free and open-source software is usually restricted, either by not providing the corresponding source code or by preventing reinstallation through technical measures, thus rendering the installed version proprietary. Most Android devices ship with additional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pixel 2
The Pixel 2 and Pixel 2 XL are a pair of Android smartphones designed, developed, and marketed by Google as part of the Google Pixel product line. They collectively serve as the successors to the Pixel and Pixel XL. They were officially announced on October 4, 2017 at the Made by Google event and released in the United States on October 19. On October 9, 2018, they were succeeded by the Pixel 3 and Pixel 3 XL. History In early March 2017, Google's Rick Osterloh confirmed that they would bring a "next-gen" Pixel smartphone later that year. He stated it would "stay premium" and that there would be no "cheap Pixel". Google originally intended to use HTC to manufacture both their 2017 flagships, but later shifted to LG to manufacture the bigger Pixel 2 XL. The unreleased device that was supposed to be the Pixel 2 XL under the codename "Muskie", was later re-developed by HTC into the HTC U11+. The Google Pixel 2 and Pixel 2 XL were carried in the United States by Verizon and Proj ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Android Nougat
Android Nougat ( codenamed Android N during development) is the seventh major version and 14th original version of the Android operating system. First released as an alpha test version on March 9, 2016, it was officially released on August 22, 2016, with Nexus devices being the first to receive the update. The LG V20 was the first smartphone released with Nougat. Nougat introduces notable changes to the operating system and its development platform, including the ability to display multiple apps on-screen at once in a split-screen view, support for inline replies to notifications, and an expanded Doze power-saving mode that restricts device functionality once the screen has been off for a period of time. Additionally, the platform switched to an OpenJDK-based Java environment and received support for the Vulkan graphics rendering API, and seamless system updates on supported devices. Nougat received positive reviews. The new app notification format received particular praise; w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ARM Cortex-A7
The ARM Cortex-A7 MPCore is a 32-bit microprocessor core licensed by ARM Holdings implementing the ARMv7-A architecture announced in 2011. Overview It has two target applications; firstly as a smaller, simpler, and more power-efficient successor to the Cortex-A8. The other use is in the big.LITTLE architecture, combining one or more A7 cores with one or more Cortex-A15 cores into a heterogeneous system. To do this it is fully feature-compatible with the A15.

Advanced Encryption Standard
The Advanced Encryption Standard (AES), also known by its original name Rijndael (), is a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology (NIST) in 2001. AES is a variant of the Rijndael block cipher developed by two Belgian cryptographers, Joan Daemen and Vincent Rijmen, who submitted a proposal to NIST during the AES selection process. Rijndael is a family of ciphers with different key and block sizes. For AES, NIST selected three members of the Rijndael family, each with a block size of 128 bits, but three different key lengths: 128, 192 and 256 bits. AES has been adopted by the U.S. government. It supersedes the Data Encryption Standard (DES), which was published in 1977. The algorithm described by AES is a symmetric-key algorithm, meaning the same key is used for both encrypting and decrypting the data. In the United States, AES was announced by the NIST as U.S. FIPS PUB 197 (FIPS 197) on Novemb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adiantum (cipher)
Adiantum is a cipher construction for disk encryption, which uses the ChaCha and Advanced Encryption Standard (AES) ciphers, and Poly1305 cryptographic message authentication code (MAC). It was designed in 2018 by Paul Crowley and Eric Biggers at Google specifically for low-powered mobile devices running Android Go. It has been included in the Linux kernel since version 5.0. HPolyC is an earlier variant of Adiantum, which uses a different construction for the Poly1305 hash function. Adiantum is implemented in Android 10 as an alternative cipher for device encryption, particularly on low-end devices lacking hardware-accelerated support for AES. The company stated that Adiantum ran five times faster than AES-256-XTS on ARM Cortex-A7 The ARM Cortex-A7 MPCore is a 32-bit microprocessor core licensed by ARM Holdings implementing the ARMv7-A architecture announced in 2011.

Clickjacking
Clickjacking (classified as a user interface redress attack or UI redressing) is a malicious technique of tricking a user into clicking on something different from what the user perceives, thus potentially revealing confidential information or allowing others to take control of their computer while clicking on seemingly innocuous objects, including web pages. Clickjacking is an instance of the confused deputy problem, wherein a computer is tricked into misusing its authority.The Confused Deputy rides again! Tyler Close, October 2008 History In 2002, it had been noted that it was possible to load a transparent layer over a web page and have the user's input affect the transparent layer without the user noticing.

Light-on-dark Color Scheme
A light-on-dark color scheme —also called black mode, dark mode, dark theme, night mode, or lights-out (mode)— is a color scheme that uses light-colored text, icons, and graphical user interface elements on a dark background. It is often discussed in terms of computer user interface design and web design. Many modern websites and operating systems offer the user an optional light-on-dark display mode. Some users find dark mode displays more visually appealing, and claim that it can reduce eye strain. Displaying white on full brightness uses roughly six times as much power as pure black on a 2016 Google Pixel, which has an OLED display. However conventional LED displays cannot benefit from reduced power consumption. Most modern operating systems support an optional light-on-dark color scheme. History Predecessors of modern computer screens, such as cathode-ray oscillographs, oscilloscopes, etc., tended to plot graphs and introduce other content as glowing traces on a bl ...

Sidebar (computing)
The sidebar is a graphical control element that displays various forms of information to the right or left side of an application window or operating system desktop. Examples of the sidebar can be seen in the Opera web browser, Apache OpenOffice, LibreOffice, SoftMaker Presentations and File Explorer; in each case, the app exposes various functionalities via the sidebar. Overview Sidebars have originated in desktop apps, which are designed for rectangular screens with longer horizontal sides. Like toolbars and status bars, sidebars host both information and GUI widgets with which the user issues commands to the app. Unlike toolbars and status bars, sidebars have larger surface areas because of horizontally longer layout of desktop apps. Sidebars may use accordions to organize widgets and accommodate a larger layout than the visible surface area. Widgets In a number of Widget engines, one is able to install applets which can reside on a sidebar. Notable examples include: * Wi ...

Android Lawn Statues
The Android lawn statues are a series of large foam statues near the Googleplex (Google's headquarters) in Mountain View, California, Mountain View, California, currently located at Charleston Rd & Huff Ave. They are based on the code names for Android version history, versions of Google's Android (operating system), Android mobile operating system, which were named after desserts and sweet treats. Google used to commission a statue for each new Android version, a tradition that ended in 2019 after the release of Android 10. Starting with Android 11, the statues are created as virtual 3D modeling, 3D models. These statues were originally located in front of Building 44, where the Android development team had its offices, before being moved to their present location a few blocks away next to the Google Visitor Center Beta. The area is open to Google employees and their guests, and visitors are encouraged to take photos. Up to 2013's KitKat, all the sculptures were made by the compa ...
