Abstract

The invention belongs to the field of computer application and particularly relates to a computer and a built-in function sub-board thereof. The built-in function sub-board comprises a USB (universal serial bus) hub, a USB option switch, a USB multiplex switch, a plurality of U disks and a conversion chip; the built-in function sub-board is connected with a main board of the computer through a serial port; the serial port is connected with the USB hub through the conversion chip from a USB to the serial port in the built-in function sub-board; and the two U disks with certain capacity are connected with the USB hub and connected with the USB option switch at the same time. A user can perform an operation of detecting, updating, deleting or the like on data in the two different U disks through the USB option switch so as to achieve isolated protection of data resources.

Description

technical field [0001] The invention belongs to the field of computer applications, in particular to a computer and its built-in function sub-board. Background technique [0002] USB (Universal Serial BUS, Universal Serial Bus) is an external bus standard, a serial bus standard for connecting computer systems and external devices, and is used to standardize the connection and communication between computers and external devices. The USB interface supports the plug-and-play and hot-swap functions of the device. [0003] Since its launch in 1996, USB has successfully replaced serial ports and parallel ports, and has become one of the must-have interfaces for personal computers and a large number of smart devices today. At present, the motherboard mainly adopts USB1.1 and USB2.0, and each USB version can be well compatible. USB uses a 4-pin (USB3.0 standard is 9-pin) plug as a standard plug, and all peripherals can be connected in a daisy chain, up to 127 external devices can...
