As originally used, firmware contrasted with hardware (the CPU itself) and software (normal instructions executing on a CPU). It was not composed of CPU machine instructions, but of lower-level microcode involved in the implementation of machine instructions. It existed on the boundary between hardware and software; thus the name firmware.
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.
The WD TV is a discontinued series of consumer digital media players produced by Western Digital designed to play videos, images, and music from USB drives, internal drives or network locations.

The Western Digital Raptor (often marketed as WD Raptor, 2.5" models known as VelociRaptor) is a discontinued series of high performance hard disk drives produced by Western Digital first marketed in 2003.
Intel claims the ME is required to provide full performance. [8] Its exact workings [9] are largely undocumented [10] and its code is obfuscated using confidential Huffman tables stored directly in hardware, so the firmware does not contain the information necessary to decode its contents. [11]
This requirement led to the development and use of specialized software such as model-based systems engineering (MBSE) tools. The application development toolset SCADE (from Ansys ) (not to be confused with the application category SCADA ) is an example of an MBSE tool and has been used as part of the development of FADEC systems.
In Windows 10 and Windows 11, the use of Windows Update is mandatory; however, the software agreement states that users may stop receiving updates on their device by disconnecting their device from the Internet. [5] [6] There also exist C and D updates, [7] that users enroll in when they click the update button. [8]
The performance and endurance of SSDs vary depending on the number of bits stored per cell, ranging from high-performing single-level cells (SLC) to more affordable but slower quad-level cells (QLC). In addition to flash-based SSDs, other technologies such as 3D XPoint offer faster speeds and higher endurance through different data storage ...
