5.1 Using the USB Port
USB (Universal Serial Bus) is a hardware interface that enables you to connect multiple
devices (such as printers, mice, keyboards, storage devices, joysticks, digital cameras, and
video conference cameras, etc.) to your notebook computer, and up to 127 devices can be
attached. Besides, USB’s hot swap capability allows everything to be plugged in and
unplugged without turning the system off.
Microsoft, HP, Compaq, Intel, Agere, NEC and Philip are seven core members of USB-IF to
have worked on USB 2.0 standardization. USB 2.0 offers data transfer rate up to 480Mbps
(megabits per second) compared to USB 1.1 devices, which transfer at speeds of 12Mbps.
This means USB 2.0 can transfer data between the computer and its peripherals 40 times
faster than USB 1.1. However, USB 2.0 is fully backward compatible, you will be able to use
a USB 1.1 device in a USB 2.0 compliant system.
