How does GigE differ from USB?

GigE is a commercial standard, and USB is consumer-oriented. USB supports up to 127 devices on a shared bus. The maximum distance between devices is 5 m. The latest version of USB (USB 2.0) has a total bus bandwidth of 480 Mb/s. All devices on the bus share this bandwidth, and may have to queue for access. By contrast, each device on a GigE network has a dedicated connection – there is no queuing for access. The maximum distance between GigE-connected devices and PCs and/or switches is 100 m. At 1 Gb/s, GigE has more than twice the bandwidth capacity of USB 2.0.
