| Question | Answer |
| ATX | motherboard form factor 12" x 9.6" AMD and Intel are top manufacturers max of 7 expansion slots |
| mATX | micro ATX form factor 9.6" x 9.6" max of 4 expansion slots |
| mini-ITX | form factor 6.7" x 6.7" used in mini towers and slim profile PCs |
| system bus | connects all of the systems primary components a highway for sharing and transmitting data |
| CPU | Central Processing Unit includes Arithmetic Logic Unit (APU) and Floating Point Unit (FPU) |
| PGA | Pin Grid Array socket where CPU goes primarily made by AMD |
| LGA | Land Grid Array socket where CPU goes primarily made by Intel |
| northbridge | one of two chips that make up the CPU's chipset handles the most critical and fastest comm., such as the CPU, RAM, and PCIe |
| southbridge | one of two chips that make up the CPU's chipset handles less critical components, such as the PCI, front panel, storage drives, etc. |
| firmware | basic or low-level software used for managing & controlling hardware components set of system and component instructions seen as a hybrid between software & hardware |
| BIOS | Basic Input/Output System system firmware - set of instructions responsible for POST stored on ROM chip on motherboard 32-bit program |
| UEFI | Unified Extensible Firmware Interface performs same purpose as BIOS 64-bit program lays on top of BIOS and adds features like secure boot and the GUID partition table (GPT) |
| TPM | Trusted Platform Module chip on motherboard that adds security functions on a hardware level supports full disk encryption on OSs that have the functionality |
| HSM | Hardware Security Module physical computing device that provides tamper-evident & intrusion-resistant safeguarding and management of all digital keys and other secrets, as well as crypto-processing |
| PCI | Peripheral Component Interconnect type of expansion bus used to connect peripherals, or internal components to the motherboard, through expansion slots |
| PCIe | PCI Express upgrade for PCI, faster and has the ability to use lanes |
| M.2 standard | a standard that defines the interface and connector used for internally attached expansion cards and SSDs commonly 2 - amongst PCIe slots and near SATA connectors smaller form factor to an SSD, and faster |
| SATA cable Serial Advanced Technology Attachment internally connect storage drives upgrade for PATA & SCSI pins: data - 7 (SD to motherboard) power - 15 (PSU to SD) | |
| Molex cable (PATA) power cable (PSU to HDDs & optical drives) -some connect to motherboard for power, such as chassis fans pins: commonly 4, but has 6 & 8 too | |
| SCSI ("scuzzy") cable Small Computer System Interface connects many types of peripheral devices can support up to 16 devices, can be used as an expansion card | |
| DE-9 (D - shape, E - size, 9 - # of pins) connect computer to console configurable devices, like routers & switches mostly been replaced by USB or Ethernet cables | |
| IEEE 1394 or FireWire data and power serial bus interface used similarly to USB, Thunderbolt, and Lightning | |
| VGA cable Video Graphics Array analog graphics standard 15-pins legacy | |
| HDMI cable High-Definition Multimedia Interface pin size - 19-type A, 29-type B other form factors - C, D, E versions - 1.1, 1.2, 1.3, 1.4, 2.0, 2.1 successor to DVI | |
| DP cable Display Port open-source competitor to HDMI greater data throughput/res. capability pin count - 20 versions - 1.2, 1.4 | |
| DVI cable Digital Visual Interface analog & digital interface for output legacy to HDMI | |
| RS-232 cable Recommended Standard DB-9 or DB-25 comm. between computers & terminal devices like a modem, router, or peripherals like a printer, mouse, or UPS | |
