What component is considered the brain of the computer?
Central Processing Unit (CPU)
Random Access Memory (RAM)
Graphics Processing Unit (GPU)
Power Supply Unit (PSU)
The CPU executes instructions and performs calculations, making it the primary processing component. It coordinates and processes data for all running software. Without the CPU, a computer cannot perform any tasks or run applications. For more information, see Wikipedia on CPUs.
Which type of memory is volatile and loses its data when the computer is powered off?
Random Access Memory (RAM)
Read-Only Memory (ROM)
Hard Disk Drive (HDD)
Solid State Drive (SSD)
RAM is designed for quick read/write access but is volatile, meaning it requires power to maintain stored data. When the system shuts down, all data in RAM is cleared. This is why important files must be saved to non-volatile storage. For more details, see RAM on Wikipedia.
Which component provides permanent storage using spinning magnetic disks?
Hard Disk Drive (HDD)
Solid State Drive (SSD)
Random Access Memory (RAM)
Graphics Processing Unit (GPU)
An HDD uses spinning platters coated with magnetic material to store data persistently. Data is written and read by moving heads over the disks. While slower than SSDs, HDDs typically offer greater capacities at lower cost per gigabyte. Learn more at Hard Disk Drive on Wikipedia.
Which device converts AC power from the outlet into DC power for computer components?
Power Supply Unit (PSU)
Motherboard
Central Processing Unit (CPU)
Graphics Processing Unit (GPU)
The PSU is responsible for converting AC power from the wall into regulated DC voltages used by all internal components. It provides multiple voltage rails and protects the system from power surges. A reliable PSU is critical for stable operation. For more information, see Computer Power Supplies on Wikipedia.
What term describes the size, layout, and mounting specifications of a motherboard?
Form factor
Chipset
Front side bus
BIOS
Form factor defines the physical dimensions, mounting holes, and connector placements of a motherboard. Common standards include ATX, Micro-ATX, and Mini-ITX. Choosing the correct form factor ensures compatibility with your case and components. See ATX Form Factors on Wikipedia.
Which port is typically colored blue and transmits analog video signals?
VGA
HDMI
DisplayPort
DVI
VGA is an older 15-pin connector carrying analog video signals. It is often colored blue to distinguish it from digital ports. Although largely superseded by DVI and HDMI, VGA remains common on legacy hardware. Read more at VGA on Wikipedia.
Which connector type is used for SATA data cables?
7-pin L-shaped connector
4-pin Molex connector
24-pin ATX connector
8-pin EPS connector
SATA data cables use a 7-pin L-shaped connector to transmit data between storage devices and the motherboard. This design prevents incorrect orientation and supports hot swapping. The SATA power connector is a separate 15-pin plug. For details, see SATA Connectors on Wikipedia.
What is the primary role of BIOS or UEFI firmware on the motherboard?
Initialize hardware and start the operating system
Store user files
Render graphics output
Regulate fan speeds only
BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) initializes hardware components and performs POST checks. After hardware initialization, it locates and loads the operating system bootloader. It also provides a setup interface for system configuration. Learn more at BIOS on Wikipedia.
Which CPU socket type is used by Intel’s 12th generation Alder Lake processors?
LGA1700
LGA1151
AM4
TRX40
Intel’s 12th generation Alder Lake CPUs require the LGA1700 socket due to their new pin layout and power delivery. This socket supports DDR5 memory and PCIe 5.0 lanes. It is not backward compatible with earlier Intel sockets. For more details, see LGA1700 on Wikipedia.
What is the main advantage of a modular power supply over a non-modular design?
Ability to detach unused cables for better airflow and cable management
Higher peak wattage output
Lower manufacturing cost
Built-in GPU support
Modular PSUs allow individual power cables to be connected or removed as needed, reducing cable clutter. This improves airflow and simplifies system builds. Non-modular units have all cables permanently attached, which may lead to excess unused wires. Read more at Modular Power Supplies on Wikipedia.
Which expansion bus interface provides the highest data throughput for modern graphics cards?
PCI Express (PCIe)
AGP
PCI
ISA
PCIe offers multiple lanes and very high serial data transfer rates, making it the standard for modern GPUs and high-speed expansion cards. AGP and PCI are older parallel technologies with much lower throughput. ISA is obsolete and not used in current systems. For more, see PCI Express on Wikipedia.
In modern CPUs, the function once handled by the Northbridge chipset is now integrated into the processor die. What does this integrated Northbridge function manage?
Memory controller and PCIe lanes
Fan speed and power supply regulation
Hard drive read/write operations
Audio signal processing
Modern CPUs include the memory controller and PCIe lanes directly on the die, roles previously managed by the Northbridge chipset. This integration reduces latency and improves overall system performance. Other chipset functions (Southbridge) handle I/O tasks separately. See more at Chipset Architecture on Wikipedia.

Cheat Sheet
Motherboard & Chipset Architecture -
The motherboard is the central hub that connects your stand alone computer's CPU, memory, and peripherals via buses and slots. Modern systems use a Platform Controller Hub (PCH) instead of separate Northbridge and Southbridge chips to streamline data flow. Think of the chipset as the traffic cop, directing signals between high-speed PCIe lanes and storage interfaces.
CPU Performance Factors -
Your CPU's clock speed (GHz), core count, and IPC (instructions per cycle) define processing power; for example, a quad-core 3.6 GHz chip can handle multithreaded tasks faster than a dual-core 2.8 GHz unit. Intel's and AMD's architecture manuals describe how features like Turbo Boost and SMT (Simultaneous Multithreading) dynamically optimize throughput. Remember the basic formula: Performance ≈ Clock Speed × IPC × Number of Cores.
Memory Hierarchy & Types -
Stand alone computer systems rely on a hierarchy from small, fast registers and L1/L2/L3 caches down to DRAM modules (DDR4/DDR5) and persistent storage. JEDEC standards specify that DDR4 DIMMs run at 2133 - 3200 MT/s, while DDR5 can exceed 4800 MT/s. Use the mnemonic "R - C - R - S" (Registers → Cache → RAM → Storage) to recall data access speeds from fastest to slowest.
Storage Interfaces & Performance -
Hard drives (SATA III at ~600 MB/s) are outpaced by NVMe SSDs on PCIe lanes, which can exceed 3 GB/s for PCIe 3.0 x4 and up to 7 GB/s for PCIe 4.0 x4 modules. Latency differences (milliseconds vs microseconds) dramatically impact boot times and file transfers in a stand alone computer system. Always check the SSD's TBW (terabytes written) rating for endurance and warranty assurances.
Power Supply & Thermal Management -
Select an 80 Plus-certified PSU rated 20 - 30% above your system's total TDP to ensure stable voltages under load. For example, a build with a 65 W CPU and 150 W GPU needs roughly a 260 W baseline, so choose a 500 W - 600 W unit for headroom. Proper airflow - intake at the front, exhaust at the rear/top - and a good CPU cooler will keep temperatures within safe operating thresholds.
