Likewise, Linux distributions include a variety of power management settings and tools. [5] There is a significant market in third-party PC power management software offering features beyond those present in the Windows operating system. [6] [7] [8] Notable vendors Data Synergy's 'PowerMAN', [9] Faronics' 'Power Save', [10] [11] and Verdiem's ...
This can often be done through a section within the BIOS, or, once an operating system is running, through a system monitor software like lm_sensors on Linux, envstat on NetBSD, sysctl hw.sensors on OpenBSD and DragonFly BSD, or SpeedFan on Windows. Most power supply fans are not connected to the speed sensor on the motherboard and so cannot be ...

Game consoles have long used specialized and customized computer hardware with the base in some standardized processor instruction set architecture. In this case, it is PowerPC and Power ISA, processor architectures initially developed in the early 1990s by the AIM alliance, i.e. Apple, IBM, and Motorola.
In 4:1:1 chroma subsampling, the horizontal color resolution is quartered, and the bandwidth is halved compared to no chroma subsampling. Initially, 4:1:1 chroma subsampling of the DV format was not considered to be broadcast quality and was only acceptable for low-end and consumer applications.
A regulated power supply is an embedded circuit; it converts unregulated AC (alternating current) into a constant DC. With the help of a rectifier it converts AC supply into DC. Its function is to supply a stable voltage (or less often current), to a circuit or device that must be operated within certain power supply limits.
An AC-AC converter with approximately sinusoidal input currents and bidirectional power flow can be realized by coupling a pulse-width modulation (PWM) rectifier and a PWM inverter to the DC-link. The DC-link quantity is then impressed by an energy storage element that is common to both stages, which is a capacitor C for the voltage DC-link or ...
Windows, OS/2, and Sun customers, faced with the lack of application software for the PowerPC, almost universally ignored the chip. IBM's Workplace OS platform (and thus, OS/2 for PowerPC) was summarily canceled upon its first developers' release in December 1995 due to the simultaneous buggy launch of the PowerPC 620.
