The Motherboard Chapter #5 Amy Hissom Key Terms Advanced Transfer Cache (ATC) — A type of L2 cache contained within the Pentium processor housing that is embedded on the same core processor die as the CPU itself. Audio/modem riser (AMR) — A specification for a small slot on a motherboard to accommodate an audio or modem riser card. A controller on the motherboard contains some of the logic for the audio or modem functionality. Back side bus — The bus between the CPU and the L2 cache inside the CPU housing. Bus speed — The speed, or frequency, at which the data on the motherboard is moving. Communication and networking riser (CNR) — A specification for a small expansion slot on a motherboard that accommodates a small audio, modem, or network riser card. CISC (complex instruction set computing) — Earlier CPU type of instruction set. Cooler — A combination cooling fan and heat sink mounted on the top or side of a processor to keep it cool. Discrete L2 cache — A type of L2 cache contained within the Pentium processor housing, but on a different die, with a cache bus between the processor and the cache. Dual-voltage CPU — A CPU that requires two different voltages, one for internal processing and the other for I/O processing. Execution Trace Cache — A type of Level 1 cache used by some CPUs to hold decoded operations waiting to be executed. Expansion bus — A bus that does not run in sync with the system clock. EPIC (explicitly parallel instruction computing) — The CPU architecture used by the Intel Itanium chip that bundles programming instructions with instructions on how to use multiprocessing abilities to do two instructions in parallel. External cache — Static cache memory, stored on the motherboard or inside the CPU housing, that is not part of the CPU (also called L2 or L3 cache). Faceplate — A metal plate that comes with the motherboard and fits over the ports to create a well fitted enclosure around them. Front-side bus — See system bus. Heat sink — A piece of metal, with cooling fins, that can be attached to or mounted on an integrated chip (such as the CPU) to dissipate heat.

Host bus — See memory bus or system bus. I SA (Industry Standard Architecture) slot — An older slot on the motherboard used for slower I/O devices, which can support an 8-bit or a 16-bit data path. ISA slots are mostly replaced by PCI slots. Instruction set
