Study Notes
Motherboard and Components Selection
- Motherboard form factor must match compatible computer case and power supply.
- Example: An ATX motherboard requires both ATX-compatible case and power supply.
- Bigger cases offer potential for future expansion; smaller cases save space.
- Ideal computer cases should be durable, serviceable, and provide room for expansion.
Power Supply Considerations
- Check pre-installed power supply in cases for adequate wattage.
- Essential for supplying sufficient power for all installed components.
Cooling Solutions
- Internal components generate heat; case fans are critical for airflow management.
- Proper fan installation must ensure cool air enters and hot air exits effectively.
- Fan size factors include:
- Common sizes: 120mm, 140mm, and 200mm.
- Airflow rating (CFM) is crucial for cooling efficiency.
- Noise levels (dBA) should be minimized for quieter operation.
- Aesthetics, such as RGB lighting, can enhance visual appeal.
- Budget considerations to maximize value.
Power Supply Unit (PSU) Selection
- Wattage must meet total power consumption needs with headroom for stability and upgrades.
- High efficiency ratings important (80 PLUS Bronze to Titanium for energy efficiency).
Processor Speed and Architecture
- Modern processors' speed measured in GHz; maximum speed indicates functioning limit.
- Speed limitations arise from:
- Transmission Delay: Data transmission through transistors experiences delays.
- Heat Generation: Increased processor speed generates more heat, leading to potential errors.
Front-Side Bus (FSB)
- FSB connects CPU to Northbridge, facilitating data transfer between components.
- Frequency of the FSB measured in MHz; affects overall CPU operating frequency.
Processor Types
- Processors classified as 32-bit or 64-bit, with 64-bit handling more instructions and supporting more memory.
- Operating systems and applications must support 64-bit to utilize its full capabilities.
RAM Compatibility and Selection
- Choose RAM matching the motherboard; dual channel configurations enhance performance.
- Memory categorized as:
- Unbuffered: Faster, regular memory for most computers.
- Buffered: Used for servers, incorporating a control chip for managing large RAM amounts.
Internal Storage Devices
- Failing storage device signs include odd noises, vibrations, error messages, or data corruption.
- Internal drives typically connect via SATA; external drives use USB or Thunderbolt.
- Common HDD sizes: 3.5 inches (internal), 2.5 inches (SSDs).
Expansion Cards
- Often referred to as adapter cards, add specific functionalities or replace faulty onboard functions.
- NICs enhance wireless capabilities or bandwidth.
- Capture cards enable video recording and need appropriate processing power and storage.
Expansion Slots
- Adapter cards fit into PCI (older cards) and PCI Express (PCIe) slots.
- PCIe slots come in various lengths, providing different speeds and compatibility.
Media Card Formats
- Various media card formats include SD, microSD, MiniSD, and CompactFlash for storage in digital devices.
- SD cards can hold up to 2 TB; compact formats are suitable for smaller devices.
Building a Computer
- Ensure motherboard supports required components (CPU, RAM, etc.) and architectures (Intel LGA or AMD PGA).
- Install cooling solutions and components like heat sinks and RAM modules correctly.
- Multiple types of storage solutions (HDDs, SSDs) need careful selection based on needs.
- Final assembly requires installation of adapter cards and proper connections to ensure functionality.
