Questions tagged [soc]
A system on a chip or system on chip (SoC) is an integrated circuit (also known as an "IC" or "chip") that integrates all components of a computer or other electronic systems. It may contain digital, analog, mixed-signal, and often radio-frequency functions—all on a single substrate. SoCs are very common in the mobile computing market because of their low power consumption. A typical application is in the area of embedded systems.

Is there a theoretical possibility of having a full computer on a silicon wafer instead of a motherboard?
I have not seen a single reference where a whole computer is built inside a chip itself instead of modularizing and spreading it on a board.
I acknowledge that having modular parts enable versatility, ...
