About the Flashcards
Flashcards for the CompTIA A+ exam provide a focused review of core PC hardware terminology and component functions. Each card reinforces concise definitions and the roles of parts such as the CPU, motherboard, RAM (DDR4/DDR5), storage devices (HDD/SSD), GPU, and PSU to prepare students for recall-style questions.
It also reviews motherboard features (form factors, PCIe, DIMM), firmware and startup concepts (BIOS/UEFI, POST, CMOS battery), cooling and power management (heatsinks, thermal paste), and common ports and peripherals (USB-C, HDMI, Thunderbolt, monitors, printers) so learners can match terms to functions quickly. Cards emphasize performance differences, quick definitions, and common connectors for efficient exam-style drilling.
Topics covered in this flashcard deck:
- CPU and motherboard functions
- RAM types and roles
- Storage devices and differences
- GPU and VRAM basics
- Firmware and startup concepts
- Ports and peripherals
