True or false: Some computing devices do not contain a motherboard.

Question

BlackTom AI · Accepted Answer

A motherboard is a main printed circuit board (PCB) that connects a computer’s CPU, memory, storage interfaces, and peripheral buses. However, many computing devices either integrate those functions into a single chip or use a simple single-board design that is not a separate “motherboard” as in desktop PCs. Therefore the correct answer is True.

1) Relevant knowledge points and concepts
- Motherboard: a primary PCB that interconnects modular components (CPU socket, RAM slots, expansion slots).
- System-on-Chip (SoC) / microcontroller / ASIC: integrates CPU, memory controllers, and peripherals into one chip, eliminating the need for a separate motherboard.
- Embedded and single-purpose devices often use dedicated PCBs or chips rather than a modular motherboard.

2) Step-by-step reasoning
- The statement claims “Some computing devices do not contain a motherboard.” To evaluate it, consider types of computing devices.
- High-end desktops and many laptops use a distinct motherboard/logic board. But many other devices (digital watches, simple calculators, basic IoT sensors, many embedded controllers, USB thumb drives) are implemented using microcontrollers, SoCs, or custom PCBs where there is no separate motherboard concept.
- Because at least one valid example exists where no motherboard is present, the universal claim “all computing devices contain a motherboard” would be false, so the original statement (“Some do not”) is true.

3) Intermediate “steps” / examples
- Example: a simple digital thermometer uses a single microcontroller chip with onboard memory/peripherals — no motherboard.
- Example: an ASIC in a router or a smart sensor integrates functions into one package; the device has no modular motherboard.

4) Why the correct answer is correct
- The existence of many computing devices implemented without a separate motherboard directly supports the statement that some computing devices do not contain a motherboard.

5) Why the other option is incorrect
- “False” would claim every computing device contains a motherboard. That is contradicted by the many embedded/SoC-based devices and single-chip implementations.

6) Conclusion
- Confirming the provided answer: True.
