USB data line applications more widely, you can easily transfer data fast and stable, supports all types of computer; the disadvantage is the higher price band IC, another part of the data line does not support brush machine function.

USB is the most widely used external bus standard applications on the PC field, a specification for a computer with an external device connection and communication, USB interface supports setting usb data cable

Plug and Play and hot swap capabilities prepared. With the rapid development of computer hardware, USB applications increases the speed of data transfer between external devices and increase the speed of the maximum benefit for users is that means that users can use to more efficient external device such as a scanner with USB 2.0, sweep a picture of just 0.1 seconds to 4M or so, work efficiency is improved.

Depending on the USB interface cable, support equipment: mouse, keyboard, printer, scanner, camera, flash disk, MP3, mobile phones, digital cameras, mobile hard disk, external optical floppy, USB card, ADSL Modem, Cable Modem and other electronic products.

USB2.0 and 3.0

USB3.0 is USB3.0 promotion team of Intel, Microsoft, Hewlett-Packard, Texas Instruments, NEC, ST-NXP other industry giants composed in November 18, 2008 announced that it has formally completed and publicly released USB3.0 standard. USB3.0 standard provides ten times the USB 2.0 transfer speeds and higher energy efficiency can be widely used in PC peripherals and consumer electronics products. USB3.0 interface theoretical bandwidth up to 5Gbps, while the theoretical bandwidth of USB2.0 is 480Mbps. All high-speed USB2.0 device USB3.0 up will get better performance.

The main difference

Data is ten times the bandwidth 1. USB3.0 USB2.0 can reach 5Gb / s (480MB / s), synchronous transmission bandwidth can reach 384MB / s, which is one of the main differences between USB3.0 and 2.0;

2. Low power consumption (at the time of data transmission capacity 20MB / s is approximately less than USB2.0 25% of power);

3. USB3.0 more energy than 2.0, is waiting for a temporary device, you can use the power-saving mode;

4. USB3.0 can provide more power via the cable (2.5W upgrade to 4.5W);

5. USB3.0 is backward compatible, supports USB2.0 device, but it can not support USB2.0 USB3.0.
