Computer cooling. A finned air cooled heatsink with fan clipped onto a CPU, with a smaller passive heatsink without fan in the background. A 3-fan heatsink mounted on a video card to maximize cooling efficiency of the GPU and surrounding components. Commodore 128DCR computer's switch-mode power supply, with a user-installed 60 mm cooling fan.
AltGr key. The AltGr key is the first key to the right of the space bar. AltGr (also Alt Graph) is a modifier key found on many computer keyboards (rather than a second Alt key found on US keyboards). It is primarily used to type special characters and symbols that are not widely used in the territory where sold, such as foreign currency ...
A typical 105-key computer keyboard, consisting of sections with different types of keys. A computer keyboard consists of alphanumeric or character keys for typing, modifier keys for altering the functions of other keys, [1] navigation keys for moving the text cursor on the screen, function keys and system command keys—such as Esc and Break—for special actions, and often a numeric keypad ...
The Asus Eee PC is a subnotebook / netbook computer. At the time of its introduction in fall 2007, it was noted for its combination of a light weight, Linux -based operating system, solid-state drive and relatively low cost. Newer models have added the option of the Windows 7 operating system, dual-core Intel Atom CPUs, and traditional hard ...
Power-on self-test. A power-on self-test ( POST) is a process performed by firmware or software routines immediately after a computer or other digital electronic device is powered on. [ 1] POST processes may set the initial state of the device from firmware and detect if any hardware components are non-functional.
SpeedFan is a system monitor for Microsoft Windows that can read temperatures, voltages and fan speeds of computer components. [3] It can change computer fan speeds depending on the temperature of various components. [1] [4] The program can display system variables as charts and as an indicator in the system tray.
The turbo button is the small button below the segment display; the amber light above is a secondary indicator of the turbo button state. On IBM PC compatible computers, the turbo button selects one of two run states: the default "turbo" speed or a reduced speed closer to the Intel 8086 CPU. It was relatively common on computers using the Intel ...
In computers, various types of computer fans are used to provide adequate cooling, and different fan control mechanisms balance their cooling capacities and noise they generate. This is commonly accomplished by the motherboards having hardware monitoring circuitry, which can be configured by the end-user through BIOS or other software to ...
