On smartphones, tablets, and other devices, an over-the-air update is a firmware or operating system update that is downloaded by the device over the internet. Previously, users had to connect these devices to a computer over USB to perform an update. These updates may add features, patch security vulnerabilities, or fix software bugs.
Firmware is commonly stored in an EEPROM or Flash memory, [1] which makes use of an I/O protocol such as SPI. In computing, firmware is software that provides low-level control of computing device hardware. For a relatively simple device, firmware may perform all control, monitoring and data manipulation functionality.
Contrary to its predecessor BIOS which is a de facto standard originally created by IBM as proprietary software, UEFI is an open standard maintained by an industry consortium. Intel developed the original Extensible Firmware Interface (EFI) specification. The last Intel version of EFI was 1.10 released in 2005.
ARM (stylised in lowercase as arm, formerly an acronym for Advanced RISC Machines and originally Acorn RISC Machine) is a family of RISC instruction set architectures (ISAs) for computer processors. Arm Ltd. develops the ISAs and licenses them to other companies, who build the physical devices that use the instruction set.
A dive computer, personal decompression computer or decompression meter is a device used by an underwater diver to measure the elapsed time and depth during a dive and use this data to calculate and display an ascent profile which, according to the programmed decompression algorithm, will give a low risk of decompression sickness.
On September 7, 2016, Sony announced a hardware revision of the PlayStation 4, model number CUH-2000, known colloquially as the PlayStation 4 Slim, which phased out the original model. [215] It is a revision of the original PS4 hardware with a smaller form factor; it has a rounded body with a matte finish on the top of the console rather than a ...
The native operating system of the PlayStation 4 is Orbis OS, which is a fork of FreeBSD version 9.0 which was released on January 12, 2012. [6] [7] The software development kit (SDK) is based on LLVM and Clang, [8] which Sony has chosen due to its conformant C and C++ front-ends, C++11 support, compiler optimization and diagnostics. [9]
Bluetooth HID is a lightweight wrapper of the human interface device protocol defined for USB. The use of the HID protocol simplifies host implementation (when supported by host operating systems) by re-use of some of the existing support for USB HID in order to support also Bluetooth HID. Keyboard and keypads must be secure.
