What Does System on a Chip (SoC) Mean?

A system on a chip (SoC) combines the required electronic circuits of various computer components onto a single, integrated chip (IC). SoC is a complete electronic substrate system that may contain analog, digital, mixed-signal or radio frequency functions. Its components usually include a graphical processing unit (GPU), a central processing unit (CPU) that may be multi-core, and system memory (RAM).

Techopedia Explains System on a Chip (SoC)

An SoC is specially designed to meet the standards of incorporating the required electronic circuits of numerous computer components onto a single integrated chip. Instead of a system that assembles several chips and components onto a circuit board, the SoC fabricates all necessary circuits into one unit.
