QuestionAnswer
Advanced Configuration and Power Interface (ACPI) In computing, the Advanced Configuration and Power Interface (ACPI) specification provides an open standard for device configuration and power management by the operating system.
back-side bus (BSB) In personal computer microprocessor architecture, a back-side bus (BSB), or backside bus, is a computer bus used to connect the CPU to CPU cache memory, usually L2.
case fan A computer fan is any fan inside, or attached to, a computer case used for active cooling, and may refer to fans that draw cooler air into the case from the outside, expel warm air from inside, or move air across a heatsink to cool a particular component.
Centrino The Centrino brand represents Intel Wi-Fi and WiMAX adapters. It was formerly a platform-marketing initiative from Intel until January 7, 2010.
chassis air guide (CAG) Chassis Air Guide or CAG in abbreviation, is Intel's thermal system to PC chassis.
Cool’n’Quiet Cool'n'Quiet is a CPU speed throttling and power saving technology introduced by AMD with its Athlon 64 processor line.
Cooler Computer fans are very widely used to reduce temperature by actively exhausting hot air. There are also more exotic and extreme techniques, such as liquid cooling.
DRAM Dynamic random-access memory (DRAM) is a type of random-access memory that stores each bit of data in a separate capacitor within an integrated circuit.
dual-core processing A multi-core processor is a single computing component with two or more independent actual central processing units (called "cores"), which are the units that read and execute program instructions.
Enhanced Intel SpeedStep Technology (EIST) SpeedStep is a trademark for a series of dynamic frequency scaling technologies and including built into some Intel microprocessors that allow the clock speed of the processor to be dynamically changed by software aka EIST.
Execute disable bit The NX bit, which stands for Never eXecute, is a technology used in CPUs to segregate areas of memory for use by either storage of processor instructions (or code) or for storage of data, a feature normally only found in Harvard architecture processors.
front-side bus (FSB) A front-side bus (FSB) is a computer communication interface (bus) often used in Intel-chip-based computers during the 1990s and 2000s.
heat sink In electronic systems, a heat sink is a passive heat exchanger component that cools a device by dissipating heat into the surrounding air. In computers, heat sinks are used to cool central processing units or graphics processors.
hyper-threading Hyper-threading is Intel's proprietary simultaneous multithreading (SMT) implementation used to improve parallelization of computations performed on PC microprocessors.
hyper transport HyperTransport (HT), formerly known as Lightning Data Transport (LDT), is a technology for interconnection of computer processors
internal bus Internal bus, also known as internal data bus, memory bus or system bus or front-Side-Bus, connects all the internal components of a computer, such as CPU and memory, to the motherboard.
Level 1 (L1) cache Multi-level caches generally operate by checking the smallest level 1 (L1) cache first; if it hits, the processor proceeds at high speed
Level 2 (L2) cache If the smaller cache misses, the next larger cache (L2) is checked, and so on, before external memory is checked
