The CPU is the "brain" of the computer, executing instructions measured in GHz (e.g., a 3.2 GHz chip handles 3.2 billion cycles per second). Think of it like a fast toll booth where each car (instruction) gets processed rapidly. Mnemonic: "Crazy Penguins Understand" to recall CPU's role in handling computations (source: Intel Education).
Random Access Memory (RAM) -
RAM is volatile memory that stores data your computer actively uses, like open apps or documents. With sizes from 4 GB to 16 GB in 6th grade PCs, more RAM means smoother multitasking (source: Kingston Tech Guides). Remember: "RAM is your desk," where a bigger desk helps you spread out your work.
Motherboard -
The motherboard is the main circuit board connecting CPU, RAM, storage, and peripherals via slots and buses. It's like a city's highway system - every component relies on its lanes to communicate (source: IEEE Spectrum). Check for key parts: chipset, PCIe slots, and power connectors.
Storage Devices (HDD vs. SSD) -
Hard drives (HDDs) use spinning disks, offering high capacity (1 TB+) at lower cost, while SSDs use flash memory for faster boot times and file access (often 500 MB/s+ read speed). Picture HDDs as vinyl records and SSDs as digital music files (source: Computer Science Review). The formula for speed difference: SSD read speed ÷ HDD read speed ≈ 10× faster.
Graphics Processing Unit (GPU) -
The GPU accelerates image and video tasks with hundreds of small cores, making games and animations smoother (source: NVIDIA Developer). Many GPUs include dedicated VRAM (e.g., 4 GB GDDR5) to store textures quickly. Mnemonic: "Great Penguins Unite" to remember GPUs handle visual workloads.
