EROFS
EROFS (Enhanced Read-Only File System) is a lightweight read-only file system initially developed by Huawei, originally for the Linux kernel and now maintained by an open-source community. EROFS aims to form a generic read-only file system solution for various read-only use cases (embedded devices, containers and more) instead of just focusing on storage space saving without considering any side effects of runtime performance. For example, it provides a solution to save storage space by using transparent compression as an option for scenarios that need high-performance read-only requirements on their devices with limited hardware resources, e.g. smartphones like Android and IoT operating systems such as HarmonyOS alongside its HarmonyOS NEXT core system iteration. All of Huawei's new products shipped with EMUI 9.0.1 or later used EROFS, and it was promoted as one of the key features of EMUI 9.1. Oppo, Xiaomi and some Samsung products also use EROFS. Also, it provides a content- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EMUI
EMUI (formerly known as Emotion UI) is an interface based on Android (operating system) developed by Chinese technology company Huawei, used on the company's smartphones primarily globally. Instead of Google Mobile Services, EMUI devices have used Huawei Mobile Services, such as the Huawei AppGallery, in January 2020 due to United States sanctions imposed during the trade war against China in May 2019. From Version 13 (2022), Huawei additionally bundled the HarmonyOS TEE microkernel with the Android system; this microkernel for example handled identity security features such as the fingerprint authentication. History On 30 December 2012, Huawei introduced Emotion UI 1.0, based on Android 4.0. It features a voice assistant app (only in Chinese), customizable homescreens and theme-switching. The company rolled out installation files for the Ascend P1 through their website. The company claims that it is "probably the world's most emotional system". On 4 September 2014 ...

HarmonyOS NEXT
HarmonyOS NEXT ( zh, s=鸿蒙星河版, p=Hóngméng Xīnghébǎn) is a proprietary software, proprietary distributed operating system that succeeded the similarly named HarmonyOS, with the main difference that the "Next" operating system was developed by Huawei to support only HarmonyOS Native (computing), native App (file format), apps. Unlike Android-based HarmonyOS versions 1 to 4 (2019-2024) and the global market EMUI operating system, the Next version (starting with HarmonyOS Next 5) does not include the Android Android (operating system), AOSP core and is incompatible with Android applications. HarmonyOS NEXT both discards the common Unix-like Linux kernel and replaces the previous multikernel system with its own bespoke HarmonyOS microkernel. The rich execution environment (REE) version of the HarmonyOS microkernel is placed at its core, with a single framework as kernel mode. The operating system shares lineage with the lightweight LiteOS real-time operating system for r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Little-endian
'' Jonathan_Swift.html" ;"title="Gulliver's Travels'' by Jonathan Swift">Gulliver's Travels'' by Jonathan Swift, the novel from which the term was coined In computing, endianness is the order in which bytes within a word (data type), word of digital data are transmitted over a data communication medium or Memory_address, addressed (by rising addresses) in computer memory, counting only byte significance compared to earliness. Endianness is primarily expressed as big-endian (BE) or little-endian (LE), terms introduced by Danny Cohen into computer science for data ordering in an Internet Experiment Note published in 1980. Also published at The adjective ''endian'' has its origin in the writings of 18th century Anglo-Irish writer Jonathan Swift. In the 1726 novel ''Gulliver's Travels'', he portrays the conflict between sects of Lilliputians divided into those breaking the shell of a boiled egg from the big end or from the little end. By analogy, a CPU may read a digital word b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inode
An inode (index node) is a data structure in a Unix-style file system that describes a file-system object such as a file or a directory. Each inode stores the attributes and disk block locations of the object's data. File-system object attributes may include metadata (times of last change, access, modification), as well as owner and permission data. A directory is a list of inodes with their assigned names. The list includes an entry for itself, its parent, and each of its children. Etymology There has been uncertainty on the Linux kernel mailing list about the reason for the "i" in "inode". In 2002, the question was brought to Unix pioneer Dennis Ritchie, who replied: A 1978 paper by Ritchie and Ken Thompson bolsters the notion of "index" being the etymological origin of inodes. They wrote: Additionally, Maurice J. Bach wrote that the word ''inode'' "is a contraction of the term index node and is commonly used in literature on the UNIX system". Details A file system ...

Mainline Linux
The Linux kernel is a free and open source Unix-like kernel that is used in many computer systems worldwide. The kernel was created by Linus Torvalds in 1991 and was soon adopted as the kernel for the GNU operating system (OS) which was created to be a free replacement for Unix. Since the late 1990s, it has been included in many operating system distributions, many of which are called Linux. One such Linux kernel operating system is Android which is used in many mobile and embedded devices. Most of the kernel code is written in C as supported by the GNU compiler collection (GCC) which has extensions beyond standard C. The code also contains assembly code for architecture-specific logic such as optimizing memory use and task execution. The kernel has a modular design such that modules can be integrated as software components including dynamically loaded. The kernel is monolithic in an architectural sense since the entire OS kernel runs in kernel space. Linux is provided un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
