| Question | Answer |
|---|---|
| What is BIOS/UEFI responsible for? | BIOS/UEFI controls boot options, fan speeds, temperature monitoring, USB permissions, and security options such as the BIOS password, boot password, TPM, HSM, and Secure Boot |
| What is standard ATX motherboard? | A standard ATX motherboard is 12" x 9.6" -has processor and memory slots at right angles |
| What is a microATX motherboard? | a microATX motherboard is 9.6" x 9.6" - smaller version of an ATX motherboard -has fewer connectors for plugging in expansion cards/peripherals |
| Are microATX motherboards compatible with ATX cases? | ATX and microATX motherboards use the same case mounting points, so a microATX board will fit into a standard ATX case. However, since MicroATX typically have smaller cases, it is unlikely that an ATX will fit into a microATX case |
| ITX | -low power, small form factor board -isn't a form factor on its own, but is a family of form factors |
| What form factors are ITX? | Mini-ITX 6.7" x 6.7" Nano- ITX 4.7" x 4.7" Pico- ITX 3.9" x 2.8" Mobile- ITX 2.4" x 2.4" |
| Can a mini ITX motherboard fit in an ATX or microATX case? | Yes! The mini ITX motherboard has 4 mounting holes that line up with three of four of the holes in the ATX and the micro ATX form factors. Mounting is compatible, but not using the same components |
| True or false: serial buses were replaced by parallel busses and then the industry switched back to serial again | True! The short circuit length of the parallel buses created throughput issues. Serial buses improved and became standard |
| What are limitations of serial buses/circuits? | The main limitation of serial circuits is the capability of the transceivers, which grows over time due to advancements in technology |
| What is the internal bus speed of a CPU derived from? | Front-side bus clock |
| What is a chipset? | A chipset is a collection of chips or circuits that perform interface and peripheral functions for the processor |
| What is a peripheral? | Peripherals are auxiliary hardware devices that connect to a computer to expand its functionality. They include input devices like keyboards and mice, output devices like printers and monitors, and storage devices such as external hard drives. |
| What features do chipsets have? | type of CPU + RAM supported, Onboard Video capabilities/outputs. Motherboard expansion slot types, versions, and speeds, number of input/output ports+ versions, and support for BIOS/UEFI security |
| What is PCI? | Peripheral Component Interconnect, is a local computer bus standard used to connect hardware devices to a computer's motherboard. It allows devices like graphics cards and sound cards to communicate with the CPU and memory. |
| True or false: when dealing with multiple PCIs the speed adjusts to the adapter with the fastest speed? | False, the speed adjusts to the slower bus |
| What is PCIe | PCI express is the new standard for expansion cards. |
