Software Over-the-air
An over-the-air update (or OTA update), also known as over-the-air programming (or OTA programming), is an update to an embedded system that is delivered through a wireless network, such as Wi-Fi or a cellular network. These embedded systems include mobile phones, tablets, set-top boxes, cars and telecommunications equipment. OTA updates for cars and internet of things devices can also be called firmware over-the-air (FOTA). Various components may be updated OTA, including the device's operating system, applications, configuration settings, or parameters like encryption keys. Terminology The term ''over-the-air update'' applies specifically to embedded systems, rather than non-embedded systems like computers. Before OTA updates, embedded devices could only be flashed through direct physical access (with a JTAG) or wired connections (usually through USB or a serial port). Purpose Over-the-air delivery may allow updates to be distributed at larger scales, reduce the cost ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Embedded System
An embedded system is a specialized computer system—a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system. It is embedded as part of a complete device often including electrical or electronic hardware and mechanical parts. Because an embedded system typically controls physical operations of the machine that it is embedded within, it often has real-time computing constraints. Embedded systems control many devices in common use. , it was estimated that ninety-eight percent of all microprocessors manufactured were used in embedded systems. Modern embedded systems are often based on microcontrollers (i.e. microprocessors with integrated memory and peripheral interfaces), but ordinary microprocessors (using external chips for memory and peripheral interface circuits) are also common, especially in more complex systems. In either case, the processor(s) us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Software Framework
In computer programming, a software framework is a software abstraction that provides generic functionality which developers can extend with custom code to create applications. It establishes a standard foundation for building and deploying software, offering reusable components and design patterns that handle common programming tasks within a larger software platform or environment. Unlike libraries where developers call functions as needed, frameworks implement inversion of control by dictating program structure and calling user code at specific points, while also providing default behaviors, structured extensibility mechanisms, and maintaining a fixed core that accepts extensions without direct modification. Frameworks also differ from regular applications that can be modified (like web browsers through extensions, video games through mods), in that frameworks are intentionally incomplete scaffolding meant to be extended through well-defined extension points and followin ...

Android Fragmentation
Fragmentation in a technology market happens when a market is composed of multiple highly-incompatible technologies or technology stacks, forcing prospective buyers of a single product to commit to an entire product ecosystem, rather than maintaining free choice of complementary products and services. Two common varieties of fragmentation are ''market fragmentation'' and ''version fragmentation''. Fragmentation is the opposite of, and is solved by standardization. Market fragmentation Market fragmentation happens when multiple competing firms offer highly-incompatible technologies or technology stacks, likely leading to vendor lock-in. Version fragmentation Version fragmentation happens when a firm offers multiple incompatible versions or variations of a single product, either in tandem or over time as a result of accumulated changes to product specification. Android and iOS operating systems A term being used in the Android development community is ''Android fragmentation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Software Bug
A software bug is a design defect ( bug) in computer software. A computer program with many or serious bugs may be described as ''buggy''. The effects of a software bug range from minor (such as a misspelled word in the user interface) to severe (such as frequent crashing). In 2002, a study commissioned by the US Department of Commerce's National Institute of Standards and Technology concluded that "software bugs, or errors, are so prevalent and so detrimental that they cost the US economy an estimated $59 billion annually, or about 0.6 percent of the gross domestic product". Since the 1950s, some computer systems have been designed to detect or auto-correct various software errors during operations. History Terminology ''Mistake metamorphism'' (from Greek ''meta'' = "change", ''morph'' = "form") refers to the evolution of a defect in the final stage of software deployment. Transformation of a ''mistake'' committed by an analyst in the early stages of the softw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
