Cheat Sheet
- CPU Architecture & Core Function -
In a hardware components quiz, understanding that the CPU performs instruction execution at GHz clock speeds is critical; for example, an Intel i7-9700K runs at 3.6 GHz with 8 cores. Recall IPC (instructions per cycle) as a key performance metric - higher IPC means more work per tick. Mnemonic: "C for CPU, C for Central," to remember Central Processing Unit.
- GPU vs. CPU: Parallel vs. Serial Processing -
If a computer hardware quiz asks about graphics vs. general compute, know that CPUs excel at serial tasks while GPUs handle thousands of threads in parallel for rendering and AI workloads. NVIDIA's CUDA cores or AMD's Stream Processors showcase how GPUs distribute work across many small units. Think "G for Graphics, G for Gigantic parallelism" to lock in that distinction.
- RAM Types & Memory Hierarchy -
Computer hardware trivia often tests your grasp of SRAM (cache) vs. DRAM (main memory) and the DDR generations (e.g., DDR4 at 3 200 MT/s vs. DDR5 at 6 400 MT/s speeds). Remember the memory pyramid: Registers → L1/L2/L3 Cache → RAM → SSD/HDD. Use the phrase "R-CR-R" (Registers, Cache, RAM, ROM) to recall the order.
- Motherboard Components & Bus Architecture -
Quiz questions on motherboards often focus on the chipset's role dividing Northbridge (memory controller) and Southbridge (I/O), plus bus standards like PCIe 4.0 offering 16 GT/s per lane. SATA, USB, and NVMe interfaces all connect via specific ports and lanes - knowing each speed helps. Mnemonic: "NBC & SBI" (Northbridge, Southbridge, I/O) keeps the flow clear.
- Storage Devices & I/O Performance -
In a computer parts quiz, distinguish HDDs (magnetic platters, ~150 MB/s) from SATA SSDs (~550 MB/s) and NVMe SSDs (up to 3 500 MB/s, using PCIe lanes). IOPS (Input/Output Operations Per Second) measures responsiveness - SSDs typically reach tens of thousands of IOPS vs. HDD's hundreds. Remember "H for Heads & Magnetic, S for Solid State" to tag each technology.
