| For these reasons, we rarely see CPUs alone in the wilderness. More often, they are integrated -- either soldered or socketed -- into **Printed Circuit Boards** (PCBs) which integrate all of those extra components. This makes **a computing system**. | For these reasons, we rarely see CPUs alone in the wilderness.

| Note that a PCB is still necessary to solder the SoC on (since it's pretty fragile on its own), mainly due to the fact that we need its small pins exposed as connectors to enable communication with the outside world! Hence, the **Single Board Computer** (SBC) category is often used for describing such computers (although the majority of boards make up the innards of various commercial electronic products). | Note that a PCB is still necessary to solder the SoC on (since it's pretty fragile on its own), mainly due to the fact that we need its small pins exposed as connectors to enable communication with the outside world!
