With the rapid development of computer hardware, the increasing number of peripherals, keyboard, mouse, modem, printer, scanner and other products use more and more frequently, then how to access these devices personal computer? This requires the use of usb connector , Then enter our theme today: usb connector is what? What is the role?

What is a USB connector?

USB Chinese name for the universal serial bus. This is in recent years gradually in the field of PC widely used in the new interface technology. USB interface has the characteristics of faster transmission, hot swapping and connecting multiple devices. Has been widely used in various types of external equipment. Currently there are three USB interface: USB1.1 and USB2.0, and in recent years the usb3.0. In theory, USB1.1 transmission speed can reach 12Mbps / sec, while the USB2.0 can reach the speed of 480Mbps / s, and can be backward compatible with USB1.1.

Second, usb3.0 connector what role?

usb3.0 connector role, simply is: you can easily add equipment for the pc, while not taking the computer's parallel port and serial port. In theory, as long as the equipment plug, you can work.

usb3.0 connector has:

* High transfer capacity, USB 3.0, also known as ultra-high-speed USB, the transmission speed than the previous generation of USB 2.0 fast 10 times faster, from 480 Mbps to 4.8 Gbps.

· High power supply, the use of USB 3.0 charging connector for electronic products, charging time will be able to save more than half.

· "High energy consumption", USB 3.0 control chip into intelligent energy-saving design, it has a green "power management" concept.

· Full support for older standard devices, USB 3.0 can be backward compatible with USB 2.0 interface applications.

USB 3.0 applications will seize the market from external storage devices, including external hard drives, solid state drives, mobile hard drives, memory cards and other products, and then gradually spread to notebook computers, desktop computers, mobile phones and other devices
