A signal is transmitted to the main unit 4 by the peripheral equipment 5 and processed, and a signal transmitted and received from the main unit 4 is received and processed.

When peripheral equipment having a general conventional interface standard connector (for example, interface standard such as PS2, LPT, 1394, USB, etc.) is connected to the interface standard connector corresponding to the main machine, the Equipment driving program must be installed. Once the drive program has been installed, a switch-off and restart must take place. Therefore, after complicated work, the use of peripheral equipment is started. If the connector of the peripheral equipment is removed from the connector of the main engine during operation, an error will occur in the computer and the computer will not be able to operate. If multiple peripherals are linked to the main engine, the computer connector shortage will increase the probability of computer failure.

When a USB connector is connected, a driving program for peripheral equipment must be installed. When the driving program is installed, the use of peripheral equipment is started. The computer can be used when the peripheral connector is disconnected from the main engine connector during operation. The peripheral equipment connectors are reconnected to the main engine and reused. Because the operation is very convenient, USB connectors are mainly used for the peripheral equipment at present.
