System Components in CompTIA A+ refer to the essential hardware and software parts that make up a computer system.
Central Processing Unit (CPU): The brain of the computer that processes instructions. Key specifications include cores, clock speed (measured in GHz), cache size, and socket type.
Motherboard: The main circuit board connecting all components. Features include form factor (ATX, micro-ATX), chipset, expansion slots (PCIe, PCI), and socket type which must match the CPU.
Random Access Memory (RAM): Temporary storage for running programs. Specifications include type (DDR4, DDR5), capacity, speed, and form factor (DIMM for desktops, SO-DIMM for laptops).
Storage devices: Hard Disk Drives (HDDs) offer high capacity at lower cost, while Solid State Drives (SSDs) provide faster performance. M.2 and NVMe drives offer even greater speeds.
Power Supply Unit (PSU): Converts AC power to DC power for components. Important specifications include wattage rating, efficiency certification (80+ Bronze/Silver/Gold), and modularity.
Cooling systems: Heat sinks, fans, and liquid cooling solutions that maintain safe operating temperatures.
Expansion cards: Graphics Processing Units (GPUs), sound cards, network interface cards that add functionality.
Input/Output interfaces: USB ports, audio jacks, display connections (HDMI, DisplayPort, VGA, DVI).
Firmware: BIOS/UEFI that initializes hardware during boot and provides configuration options.
Peripherals: Keyboards, mice, monitors, printers, and other external devices.
Case/chassis: Houses and protects internal components while facilitating airflow.
CompTIA A+ certification tests technical understanding of how these components work together, compatibility requirements, installation procedures, and troubleshooting methodologies when components malfunction.System Components in CompTIA A+ refer to the essential hardware and software parts that make up a computer system.
