Introduction / Context:
The central platform that interconnects a computer’s core components determines performance, expandability, and compatibility. Correct terminology is essential for IT support, PC assembly, and hardware troubleshooting.
Given Data / Assumptions:
- We seek the industry term for the main printed circuit board in a PC.
- It carries sockets/slots for CPU, RAM, storage interfaces, and I/O.
- Distractors include generic or irrelevant terms.
Concept / Approach:
The
motherboard (also called mainboard or system board) integrates the chipset, power delivery, firmware (UEFI/BIOS), and buses (PCIe, memory channels). Other listed words are not names for the primary system PCB in standard computer terminology.
Step-by-Step Solution:
Identify the role: houses CPU, RAM, expansion slots, connectors.Match to the standard hardware term: motherboard.Eliminate terms not used for system PCBs.
Verification / Alternative check:
PC vendor documentation and service manuals consistently label the main system PCB as the motherboard or mainboard.
Why Other Options Are Wrong:
Decoder/Highlight/Select: These are functions or interface terms, not the main PCB’s name.
Common Pitfalls:
Confusing daughtercards (e.g., graphics cards) with the motherboard; daughtercards plug into the motherboard’s expansion slots.
Final Answer:
Motherboard
