The computer uses the CPU, memory, disk, and graphics card installed directly on the motherboard. The communication between the components is more efficient. At the same time, in order to better meet the needs of entertainment and office, the performance of computer configuration is generally higher.

The IPC uses a bus structure and modular design. It has a passive motherboard and the components are modular motherboards. the CPU motherboard must be plugged into a dedicated slot in the passive motherboard. Other modular expansion boards are inserted into the expansion slots of the passive motherboard. The resistors, capacitors, and inductors on each module are designed with stronger anti-interference capability.
