Power managementPower management is a feature of some electrical appliances, especially copiers, computers, computer CPUs, computer GPUs and computer peripherals such as monitors and printers, that turns off the power or switches the system to a low-power state when inactive. In computing this is known as PC power management and is built around a standard called ACPI which superseded APM. All recent computers have ACPI support.
United States Environmental Protection AgencyThe Environmental Protection Agency (EPA) is an independent agency of the United States government tasked with environmental protection matters. President Richard Nixon proposed the establishment of EPA on July 9, 1970; it began operation on December 2, 1970, after Nixon signed an executive order.
Energy StarEnergy Star (trademarked ENERGY STAR) is a voluntary energy-efficiency program established by the U.S. Environmental Protection Agency (EPA) in 1992. The program is jointly administered by the EPA and the U.S. Department of Energy (DOE). In March 2026, the DOE was designated the lead federal agency, with the transfer of program responsibilities targeted for completion by July 2027.
Analog televisionAnalog television is the original television technology that uses analog signals to transmit video and audio. In an analog television broadcast, brightness, color, and sound are represented by the amplitude, phase, and frequency of the signal. The strength of an analog signal varies over a continuous range of possible values, meaning that electronic noise and interference may be introduced. Thus, a moderately weak signal becomes snowy and subject to interference.
ScreensaverA screensaver (or screen saver) is software that controls a monitor of the host computer with the intent of preventing screen burn-in for a screen susceptible to it. Generally, a screensaver starts controlling a monitor when the computer has been idle for a designated period of time and fills the screen either with black (all pixels off) or with changing graphics that tend to prevent each pixel from being on for a long time.StandardizationStandardization (American English) or standardisation (British English) is the process of implementing and developing technical standards based on the consensus of different parties that may include firms, users, interest groups, standards organizations and governments. Standardization can help maximize compatibility, interoperability, safety, repeatability, efficiency, and quality. It can also facilitate a normalization of formerly custom processes.
XfceXfce (pronounced as four individual letters, ) is a free and open-sourcedesktop environment for Linux and other Unix-like operating systems. Xfce aims to be fast and lightweight while still visually appealing and easy to use. The desktop environment is designed to embody the traditional Unix philosophy of modularity and re-usability, as well as adherence to standards; specifically, those defined at freedesktop.org.
Video Electronics Standards AssociationVESA (), formally known as Video Electronics Standards Association, is an American technical standards organization for computer display standards. The organization was incorporated in California in July 1989 and has its office in San Jose. It claims a membership of over 300 companies.Microsoft WindowsWindows is a proprietary operating system developed by Microsoft. Windows is grouped into families that cater to particular sectors of the computing industry – Windows for personal computers, Windows Server for servers, and Windows IoT for embedded systems. Windows itself is further grouped into editions that cater to different users – Home for home users, Professional for advanced users, Education for schools, and Enterprise for corporations.
Computer monitorA computer monitor is an output device that displays information in pictorial or textual form. A discrete monitor comprises a visual display, support electronics, power supply, housing, electrical connectors, and external user controls. The display in modern monitors is typically an LCD with LED backlight, having by the 2010s replaced CCFLbacklit LCDs. Before the mid-2000s, most monitors used a cathode ray tube (CRT) as the image output technology.
MacOSOperating system for Apple computersOperating systemmacOS (previously OS X and originally Mac OS X) is a proprietary Unix operating system, derived from OPENSTEP for Mach and FreeBSD, which has been marketed and developed by Apple since 2001. It is the current operating system for Apple's line of Mac computers.VESA BIOS ExtensionsVESA BIOS Extensions (VBE) is a VESA standard, currently at version 3, that defines the interface that can be used by software to access compliant video boards at high resolutions and bit depths. This is opposed to the "traditional" INT 10h BIOS calls, which are limited to resolutions of 640×480 pixels with 16 colour (4-bit) depth or less. VBE is made available through the video card's BIOS, which installs some interrupt vectors that point to itself during boot up.
Super VGASuper VGA (SVGA) or Extended VGA is a broad term that covers a wide range of computer display standards that extended IBM's VGA specification. When used as shorthand for a resolution, as VGA and XGA often are, SVGA refers to a resolution of 800 × 600. HistoryIn the late 1980s, after the release of IBM's VGA, third-party manufacturers began making graphics cards based on its specifications with extended capabilities.*As an Amazon Associate I earn from qualifying purchases.
