Dynamic voltage scalingIn computer architecture, dynamic voltage scaling is a power management technique in which the voltage used in a component is increased or decreased, depending upon circumstances. Dynamic voltage scaling to increase voltage is known as overvolting; dynamic voltage scaling to decrease voltage is known as undervolting. Undervolting is done in order to conserve power, particularly in laptops and other mobile devices, where energy comes from a battery and thus is limited, or in rare cases, to increase reliability.
Mobile deviceA mobile device (or handheld computer) is a computer, small enough to hold and operate in the hand. Mobile devices typically have a flat LCD or OLED screen, a touchscreen interface, and digital or physical buttons. They may also have a physical keyboard. Many such devices can connect to the Internet and connect with other devices such as car entertainment systems or headsets via Wi-Fi, Bluetooth, cellular networks or near field communication.
PlayStation PortableThe PlayStation Portable (PSP) is a handheld game console developed and marketed by Sony Interactive Entertainment. It was first released in Japan on December 12, 2004, in North America on March 24, 2005, and in PAL regions on September 1, 2005, and is the first handheld installment in the PlayStation line of consoles. As a seventh generation console, the PSP competed with the Nintendo DS. Development of the PSP was announced during E3 2003, and the console was unveiled at a Sony press conference on May 11, 2004.
Standby powerStandby power, also called vampire power, vampire draw, phantom load, ghost load or leaking electricity refers to the way electric power is consumed by electronic and electrical appliances while they are switched off (but are designed to draw some power) or in standby mode. This only occurs because some devices claimed to be "switched off" on the electronic interface, but are in a different state. Switching off at the plug, or disconnecting from the power point, can solve the problem of standby power completely.
Portable Media CenterPortable Media Center (PMC) is a portable media player (PMP) platform developed by Microsoft. Announced at the 2003 Consumer Electronics Show (CES), and released in early 2004, it was originally positioned as a competitor to Apple's iPod. All its hard drive-based players use a graphical user interface (GUI) modeled after Media Center, a software portal bundled with Windows XP Media Center Edition. Manufacturers of PMC devices included Creative, Philips, iriver, Samsung, and Toshiba.
VaioVAIO (バイオ) is a brand of personal computers and consumer electronics, currently developed by Japanese manufacturer VAIO Corporation, headquartered in Azumino, Nagano Prefecture. VAIO was originally a brand of Sony, introduced in 1996. In February 2014, Sony created VAIO Corporation Inc., a special purpose company with investment firm Japan Industrial Partners, as part of its restructuring effort to focus on mobile devices.
Dynamic frequency scalingDynamic frequency scaling (also known as CPU throttling) is a power management technique in computer architecture whereby the frequency of a microprocessor can be automatically adjusted "on the fly" depending on the actual needs, to conserve power and reduce the amount of heat generated by the chip. Dynamic frequency scaling helps preserve battery on mobile devices and decrease cooling cost and noise on quiet computing settings, or can be useful as a security measure for overheated systems (e.g.
Solid-state driveA solid-state drive (SSD) is a solid-state storage device that uses integrated circuit assemblies to store data persistently, typically using flash memory, and functioning as secondary storage in the hierarchy of computer storage. It is also sometimes called a semiconductor storage device, a solid-state device or a solid-state disk, even though SSDs lack the physical spinning disks and movable read–write heads used in hard disk drives (HDDs) and floppy disks. SSD also has rich internal parallelism for data processing.
Computer performanceIn computing, computer performance is the amount of useful work accomplished by a computer system. Outside of specific contexts, computer performance is estimated in terms of accuracy, efficiency and speed of executing computer program instructions. When it comes to high computer performance, one or more of the following factors might be involved: Short response time for a given piece of work. High throughput (rate of processing work). Low utilization of computing resource(s). Fast (or highly compact) data compression and decompression.
Compaq PortableThe Compaq Portable is an early portable computer which was one of the first IBM PC compatible systems. It was Compaq Computer Corporation's first product, to be followed by others in the Compaq Portable series and later Compaq Deskpro series. It was not simply an 8088-CPU computer that ran a Microsoft DOS as a PC "work-alike", but contained a reverse-engineered BIOS, and a version of MS-DOS that was so similar to IBM's PC DOS that it ran nearly all its application software.
