Study Notes
Central Processing Unit (CPU)
- Essential microchip that processes all instructions from user input or software.
- Requires cooling systems to manage heat generated during processing.
CMOS Battery
- Small lithium coin cell battery that powers the real-time clock and maintains BIOS settings.
- Average lifespan ranges from two to ten years.
RAM Slot
- Component that houses memory chips; common in end-user computers with two to four slots.
- Colored pairs indicate dual-channel memory configuration, promoting efficient performance.
Chipset
- Integrated circuit set that manages communication between the CPU and other components.
- Comprised of two main chips that facilitate data routing.
SATA Connectors
- Serial AT Attachment connectors that interface modern hard drives, SSDs, and optical drives with the motherboard circuitry.
IDE Connectors
- Integrated Drive Electronics connectors used for connecting hard disk and optical drives.
- Two IDE drives share one data cable; must configure one drive as master and the other as slave.
ATX Power Connector
- A 24-pin connector linking the power supply to the motherboard, delivering multiple voltage levels (3.3V, 5V, and 12V DC).
- Older models may feature a 20-pin connector, while very old systems use two six-pin connectors.
ATX 12V Power Connector
- A 4-pin connector providing additional 12V power from the power supply to the CPU.
- High-performance motherboards may require an 8-pin EPS 12V power connector for optimal functionality.
Fan Connector
- A three or four pin connector for CPU or case cooling fans, ensuring proper airflow and heat management.
- Common pin configuration: electrical ground, power, and sense output for fan speed monitoring; an optional control pin can adjust rotational speed.
Front Panel Connector and USB Headers
- System panel connector housing sockets for five crucial system cables: power button, reset button, power LED, hard disk activity LED, and internal speaker.
eSATA
- External SATA interface enabling the connection of external hard drives, SSDs, and optical drives to a computer.
