Ntldr The OS boot record program for Windows XP.
On-board ports Ports that are directly on the motherboard, such as a built-in keyboard port or on-board serial port.
partician table This table tells BIOS how many partitions the drive has, where each partition begins and ends, and which partition is used for booting (called the active partition).
PCI (Peripheral Component Interconnect) Buses have been improved several times. There are currently three major categories and within each category, several variations of PCI.
PCI Express (PCIe) PCI Express uses a serial bus, which is faster than a parallel bus because it transmits data in packets similar to how an Ethernet network, USB, and FireWire transmit data.
pin grid array (PGA) Sockets aligned with pins aligned in uniform rows around the socket. Used in earlier Pentiums.
power-on password A password that a computer uses to control access during the boot process.
program file A program file contains a list of instructions stored in a file.
riser card A card that plugs into a motherboard and allows for expansion cards to be mounted parallel to the motherboard. Expansion cards are plugged into slots on the riser card.
SLI (Scalable Link Interface) NVIDIA’s technology for installing two video cards on a motherboard.
soft boot A soft boot, or warm boot, involves using the operating system to reboot.
South Bridge The slower hub in the Accelerated Hub Architecture.
staggered pin grid array (SPGA) Having the pins staggered over the socket to squeeze more pins into a small space.
standoffs Round plastic or metal pegs that separate the motherboard from the case, so that components on the back of the motherboard do not touch the case.
track Concentric circles on a hard drive. Each track is divided into segments called sectors, and each sector can hold 512 bytes of data.
user password A password enabling you to logon to the operating system.
wait state A clock tick in which nothing happens. Used to ensure that the microprocessor is not getting ahead of slower components. A 0-wait state is preferable to a 1-wait state.
zero insertion force (ZIF) sockets Square or nearly square sockets so that even force is applied when inserting the processor in the socket, all current processor sockets have a lever on the side of the socket.
