Study Notes
Motherboard Form Factors
- Specifications define dimensions, power supply type, mounting hole locations, and back panel ports.
Central Processing Unit (CPU)
- Carries out instructions of computer programs through arithmetic, logical, and I/O operations.
- Clock Speed: Measures the number of instructions processed per second.
- Front Side Bus (FSB): Connects the CPU to system memory, allowing improved performance based on transfer speed.
- Cache: Memory that enables the CPU to quickly access recently used data.
CPU Types
- 32-bit (x86): Older architecture, processes instructions less efficiently.
- 64-bit (x64): Newer architecture, capable of handling more data simultaneously.
Random Access Memory (RAM)
- Volatile memory that requires power to retain data, losing all information when powered off.
- Single Inline Memory Module (SIMM): Used in early PCs, smaller (3.5 inches) with 30 pins; obsolete in modern systems.
- SDRAM DIMM: Enhanced modules for Pentium and AMD CPUs, features 168 pins and increased speed.
- RDRAM: Developed by Rambus, known for high speed and costly design with heat shields.
- DDR SDRAM: Competitor to RDRAM, utilizes memory bus efficiently for faster processing.
- DDR2 SDRAM: Released in 2003, offers higher speeds, greater bandwidth, and reduced power consumption.
Hard Disk Drive
- Essential for computer functionality, stores operating system files, software, and user data, retaining information even when powered off.
Power Supply Unit (PSU)
- Converts direct current (DC) power for the motherboard and peripherals.
- Includes various connectors:
- Berg: For floppy disks.
- Molex: For IDE devices like hard disks.
- SATA: Specifically for SATA devices.
- 24-pin ATX: Main power connector for the motherboard.
- 4-pin ATX: Provides +12 VDC to processor.
- PCIe Power Connector: Supplies power to graphics cards.
Graphics Card
- Also known as video adapter or display card; generates image output for displays.
Expansion Buses
- PCI (Peripheral Component Interconnect): 32-bit and 64-bit versions, prevalent until replaced by PCI Express.
- AGP (Accelerated Graphics Port): Designed primarily for GPUs, offering 266 MBps bandwidth compared to PCI.
- PCI Express (PCIe): High-speed replacement for PCI and AGP, approved in 2002.
Graphics Card Interfaces
- DisplayPort: Digital interface for transmitting video, audio, and USB signals.
- HDMI (High Definition Multimedia Interface): Transmits high-definition video and audio signals over a single cable.
- DVI (Digital Visual Interface): Standard for digital displays, compatible with flat panels and projectors.
- Analog D-Sub: Standard interface for connecting analog monitors, allowing up to 12 Mbps data transfer.
Input/Output (I/O) Ports
- Line In: Connects external audio devices for sound input.
- Line Out: Connects speakers or headphones for audio output.
- MIC Port: Allows microphone connection to capture audio signals.
