| AT | Advanced Technology; form factor that came after the XT but before the Baby AT and ATX form factors; the power supplies had 2 connectors powering the motherboard and a hard-wired switch to power the case. |
| ATX | Advanced Technology Extended; form factor that came after the Baby AT form factor having one power connector going to the motherboard and also supporting a soft power switch. |
| BIOS | The small program that resides on a ROM chip and is used to start the computer and control the way devices in the computer talk to each other. |
| BTX | Balanced Technology Extended, motherboard form factor for low profile cases that allowed for better cooling. |
| Chipset | The specialized IC's on the motherboard that helps the CPU to work with memory or the expansion boards, also known as northbridge and southbridge. |
| CMOS | Same as BIOS setup; program that allows the configuration settings, such as hard drive type, time and date settings, and boot order, to be manipulated. |

| Firmware | Program stored in ROM that holds its contents with the power removed. |
| Form factor | The specifications and size of a motherboard or power supply. |
| Integrated | A component that could operate separately but is built into another object to become one unit. |
| MicroATX | Small form factor motherboard used in PCs where reduced size is desired. |
| Motherboard | Also known as main board, planar board and system board; contains all the pathways of wires to connect the CPU to memory and the expansion boards. |
| NLX | New Low Profile Extended, low profile mother board form factor that utilizes riser cards for expansion cards. |
| Riser Card | Printed circuit board connecting to the motherboard and accepting expansion boards that will be parallel to the motherboard; examples are AMR, CNR and ACR. |
| Slot | Connector type used to hold SECC (Single Edge Contact Cartridge) processor modules used with some PII and PIII processors, memory modules and expansion cards. |
| Socket | The connector used to attach a CPU to the motherboard. |
| ZIF | Zero Insertion Force; socket type where the processor just drops in with no effort and then a level is locked down to hold the processor in place. |
