Learning the Difference Between USB 2.0 and USB 1.1

LEARNING THE DIFFERENCE BETWEEN USB 2.0 AND USB 1.1 Finalized in 2001, Universal Serial Bus (USB) 2.0 is a complete overhaul of the Universal Serial Bus input/output bus protocol which allows much higher speeds than the older USB 1.1 standard did. 1.1 2.0 USB 2.0 (High-speed USB) provides additional bandwidth for multimedia and storage applications and has a data transmission speed 40 times faster than USB 1.1. To allow a smooth transition for both consumers and USB 2.0 IS 40X manufacturers, USB 2.0 has full forward and backward compatibility with original FASTER THAN USB 1.1 USB devices and works with cables and connectors made for original USB, too. Almost every conceivable peripheral has USB 2.0 version, ranging from surround gaming headsets, portable hard drives, to even USB video cards. So, even if you buy a all-in-one HP multimedia PC with all the USB 2.0 gizmos, you'll still need something USB. 35-40 MB Actual throughput in practice is typically up to 35 - 40 MB/sec PER SECOND for USB 2.0. Voltage The USB 2.0 specification for a Full-Speed/High-Speed cable calls for four wires, two for data and Data - Data + two for power, and a braided outer shield. Ground The goal of the new serial bus is to broaden the range of external peripherals that can be used on a computer. A hard drive can easily hit the USB 1.1 bottleneck whereas it now USB2 USB 2 becomes more 'usable' under USB 2.0 conditions. USB 2.0 should neither be called "USB2' nor 'USB 2'.
