Advanced power management ( APM ) is an API developed by Intel and Microsoft and released in 1992 which enables an operating system running an IBM-compatible personal computer to work with the BIOS ( part of the computer's firmware ) to achieve power management.

This makes it a suitable replacement for older read-only memory ( ROM ) chips, which are used to store program code that rarely needs to be updated, such as a computer's BIOS or the firmware of set-top boxes.

The computer's BIOS must support booting from the device in question.

A southbridge chipset handles all of a computer's I / O functions, such as USB, audio, serial, the system BIOS, the ISA bus, the interrupt controller and the IDE channels.

ACPI is a successor to an earlier Intel-Microsoft standard called Advanced Power Management, which allows a computer's BIOS to control power management functions.

The Accelerated Graphics Port ( often shortened to AGP ) is a high-speed point-to-point channel for attaching a video card to a computer's motherboard, primarily to assist in the acceleration of 3D computer graphics.

In a computer's central processing unit ( CPU ), an accumulator is a register in which intermediate arithmetic and logic results are stored.

Application software is contrasted with system software and middleware, which manage and integrate a computer's capabilities, but typically do not directly apply them in the performance of tasks that benefit the user.

Its purpose is to unburden the application software programmer from the often complex details of the particular computer being used, including such accessories as communications devices, printers, device readers, displays and keyboards, and also to partition the computer's resources such as memory and processor time in a safe and stable manner.

The motive is often to prevent persons from viewing content which the computer's owner ( s ) or other authorities may consider objectionable ; when imposed without the consent of the user, content control can constitute censorship.

" Efficient " means that the data which is stored in the DBMS can be accessed quickly and " compact " means that the data takes up very little space in the computer's memory.

It appears in contexts where the transistor is used as a temperature sensing device, e. g. the thermal " diode " transistor that is embedded within a computer's microprocessor.

The Enhanced Chip Set ( ECS ) is the second generation of the Amiga computer's chipset, offering minor improvements over the original chipset ( OCS ) design.

Computer modems are often designated by a particular fax class, which indicates how much processing is offloaded from the computer's CPU to the fax modem.

* In computer science, lambda is the time window over which a process is observed for determining the working memory set for a digital computer's virtual memory management.

This is also known as rotational latency and seek time since the basic term latency is also applied to the time required by a computer's electronics and software to perform polling, interrupts, and direct memory access.

Polyphony, the number of sounds that can be played simultaneously, is dependent on the power of the computer's Central Processing Unit, as are the sample rate and bit depth of playback, which directly affect the quality of the sound.

The Memory Data Register ( MDR ) is the register of a computer's control unit that contains the data to be stored in the computer storage ( e. g. RAM ), or the data after a fetch from the computer storage.

Machine code or machine language is a system of impartible instructions executed directly by a computer's central processing unit ( CPU ).

Instructions per second ( IPS ) is a measure of a computer's processor speed.

This is done through synchronization software provided with the handheld, or sometime with the computer's operating system.

The source code which constitutes a program is usually held in one or more text files stored on a computer's hard disk ; usually these files are carefully arranged into a directory tree, known as a source tree.

In computability theory, a system of data-manipulation rules ( such as a computer's instruction set, a programming language, or a cellular automaton ) is said to be Turing complete or computationally universal if it can be used to simulate any single-taped Turing machine.

* ICDL Crawler is a cross-platform web crawler written in C ++ and intended to crawl Web sites based on Web-site Parse Templates using computer's free CPU resources only.

The magic packet is a broadcast frame containing anywhere within its payload 6 bytes of all 255 ( FF FF FF FF FF FF in hexadecimal ), followed by sixteen repetitions of the target computer's 48-bit MAC address, for a total of 102 bytes.

In that case, software tools like a packet analyzer can help with Wake-on-LAN troubleshooting as they allow to confirm ( while the PC is still on ) that the magic packet is indeed seen by a particular computer's NIC.

Applesoft BASIC used the ampersand as an internal command, not intended to be used for general programming, that invoked a machine language program in the computer's ROM.

An index register in a computer's CPU is a processor register used for modifying operand addresses during the run of a program, typically for doing vector / array operations.

Traditionally, one of the principles of video / computer game programming is to avoid altering the computer's video buffer except during the vertical retrace.

The computer's memory is preserved during battery changes.

The original game utilized the X68000 ’ s internal time and date settings ; the time on the clock tower during the boss fight on stage 15 would reflect the X68000 ’ s current time and the color scheme used on the painting in stage 21 would reflect one of the four seasons according to the computer's current date.

This means that while the program was active for six minutes and six seconds, during that time the computer's processor spent only 4 / 100 of a second performing calculations for the program.

In this way, JACK acts as a virtual audio patch bay, and it can be configured to use a computer's resources in real time, with dedicated memory, and with various options that minimize the DAW's latency.

Once free of the computer's influence, Lord was portrayed as an amoral businessman, but not a real villain.

This program, stored in the computer's memory and executed by ANTIC in real time, controls the GTIA video interface controller chip to create the actual screen display.

In computing, a virtual desktop is a term used with respect to user interfaces, usually within the WIMP paradigm, to describe ways in which the virtual space of a computer's desktop environment is expanded beyond the physical limits of the screen's real estate through the use of software.

It sometimes lacks the real computer's speed and accuracy, but a team of experts working simultaneously can compensate to a sufficient degree to provide an acceptable simulation.

They are often initialized using a computer's real time clock as the seed, since such a clock generally measures in milliseconds, far beyond the person's precision.

A computer's switched mode Power Supply Unit ( Computer ) | power supply unit.

When computers such as laptops go into a " hibernation " mode to save energy by shutting down the processor, the state of the processor is stored on the computer's disk, so it can be restored when the computer comes out of hibernation, and the processor can take up operations where it left off.

Many computers go into a " lockout " mode for 24 hours if the diver violates the computer's safety limits, to discourage continued diving after an unsafe dive.

The game was implemented entirely in the text mode of the PC, using various characters in the computer's character set, as well as different colors, to present a " graphical " environment.

Whereas a computer in standby mode has the computer's state saved in RAM, a system in hibernations has the state of the computer saved on the hard disk.
