Accelerated Graphics Port (AGP) 32-bit Bus designed exclusively for video cards. address bus bus system that connects CPU with main memory module. Identifies memory locations where data is stored and retrieved backplane Circuit board with slots along the length of the board. Ensures easy upgrades of any and all components bus collection of conductors that connect multiple parts, allowing them to work together for a specific purpose bus mastering allows data to be transferred directly between 2 devices without going through the CPU chipset handles data manipulation and motherboard traffic that would otherwise have to be done by the CPU CMOS setup program program that allows one to identify the hard drive type and other storage systems in the PC, select power/management features, and select boot order of storage devices control bus a bus that delivers command signals from the CPU to devices data bus a bus used to move information between PC components direct memory access (DMA) combination of software and hardware that allows certain devices access to RAM without going through the CPU Enhanced Parallel Port (EPP) parallel port standard that allows a throughput as high as 2 Mbps. Also referred to as IEEE-1284 standard expansion card slots connectors that allow devices to be quickly and easily plugged in to the bus system Extended Capabilities Port (ECP) parallel port standard that provides for bidirectional communication and has enhanced capabilities to support multiple devices Extended Industry Standard Architecture (EISA) 32-bit expansion bus, designed in response to IBM's MCA bus system. ISA cards can also fit into this slot. field replaceable unit (FRU) any major part of a computer system that could be completely replaced on site rather than repaired Firewire (IEEE1394) bus system that provides a high rate of data transfer (up to 400Mbps) and can serve up to 63 devices in a daisy-chain fashion flash BIOS BIOS that is stored on a reprogrammable chip, allowing for easy upgrades form factor the physical shape or outline of a motherboard and the location of the mounting holes I/O bus slower bus used to communicate with keyboards, mice, floppy drives, printers, etc I/O port address the memory address assigned to a device so that it may be identified by other devices Industry Standard Architecture (ISA) an I/O expansion bus system featuring a 16-bit data bus internal bus the bus that is found inside of the CPU IRQ A signal that interrupts the process taking place inside the CPU and asks that the CPU pay attention to a particular device local bus a bus system that connects directly to the CPU and provides communication to high-speed devices mounted closely to the CPU memory address range an assigned section of memory used as a temporary storage area for data before it is transferred memory bus bus that connects the CPU to RAM MicroChannel Architecture (MCA) I/O expansion bus system featuring a 32-bit data bus. Not compatible with ISA bus north bridge the portion of the chipset that controls high speed data systems such as graphics and DVD hardware Peripheral Component Interconnect (PCI) 32-bit data bus system that provides the high-speed bus structure used for faster CPUs Plug and Play (PnP) BIOS function that allows the automatic detection and configuration of new hardware components. Automatically assigns system resources such as DMA channels, IRQs, memory, port assignments power bus bus system that sends electrical power for small consumption devices such as speakers, lights, and switches south bridge the portion of the chipset that controls the slower devices associated with the PCI and ISA buses Universal Serial Bus (USB) bus system designed to replace expansion slots, with a data transfer rate of up to 480Mbps. Can support up to 127 devices in a daisy-chain configuration
