Computer Hardware Overview Quiz

Motherboard

• Definition: The main printed circuit board (PCB) in a computer that connects all components.
• Key Components:
  • CPU Socket: Holds the processor.
  • RAM Slots: Connects memory modules.
  • Expansion Slots: For additional components like GPUs.
  • Chipset: Manages data flow between CPU, memory, and peripherals.
  • Power Connectors: Supply power to the motherboard and components.
  • I/O Ports: Connect external devices (USB, HDMI, etc.).

Storage Devices

• Types:
  • Hard Disk Drive (HDD):
    • Magnetic storage, larger capacity, slower speed.
    • Mechanical components (spinning disks).
  • Solid State Drive (SSD):
    • Flash memory, faster access speeds, more durable.
    • No moving parts, lower power consumption.
• Form Factors:
  • 2.5 inch (common for laptops), M.2 (compact and high-speed), PCIe (for high-performance applications).

CPU (Central Processing Unit)

• Function: The brain of the computer, executing instructions from programs.
• Key Features:
  • Cores: Multiple cores allow for parallel processing.
  • Clock Speed: Measured in GHz, indicates processing speed.
  • Cache Memory: Small, fast memory for frequently accessed data.
  • Instruction Set Architecture (ISA): Defines how a CPU processes commands.

RAM (Random Access Memory)

• Definition: Volatile memory used for temporary storage while a computer is running.
• Key Features:
  • Types:
    • DDR (Double Data Rate), with versions like DDR3, DDR4, DDR5.
  • Capacity: Measured in GB (gigabytes), affects multitasking capability.
  • Speed: Measured in MHz, impacts overall system performance.

GPU (Graphics Processing Unit)

• Function: Specialized processor for rendering images, video, and animations.
• Types:
  • Integrated GPU: Built into the CPU, suitable for basic tasks.
  • Dedicated GPU: Separate card, better performance for gaming and graphic design.
• Key Features:
  • VRAM (Video RAM): Memory dedicated to graphics data.
  • CUDA Cores/Stream Processors: Parallel processing units for handling multiple tasks.
  • APIs: Interfaces such as DirectX and OpenGL for graphics rendering.

Motherboard

• Acts as the primary printed circuit board (PCB) connecting all computer components.
• CPU Socket: Designed to hold the processor securely.
• RAM Slots: Facilitate connection of memory modules for data storage.
• Expansion Slots: Allow for installation of additional components, such as graphics processing units (GPUs).
• Chipset: Plays a critical role in managing data flow between the CPU, memory, and other peripherals.
• Power Connectors: Provide necessary power to the motherboard and connected components.
• I/O Ports: Enable connection of external devices such as USB drives and HDMI cables.

Storage Devices

• Hard Disk Drive (HDD):
  • Utilizes magnetic storage technology; offers larger storage capacities but slower read/write speeds due to mechanical components (spinning disks).
• Solid State Drive (SSD):
  • Employs flash memory for faster data access and enhanced durability; lacks moving parts, resulting in lower power usage.
• Form Factors:
  • 2.5 inch: Commonly used in laptops.
  • M.2: Compact design tailored for high-speed performance.
  • PCIe: Optimized for high-performance applications.

CPU (Central Processing Unit)
