USB,Ethernet,Firewire-Difference between USB,Ethernet,Firewire
This page compares USB vs Ethernet vs Firewire and mentions difference between USB, Ethernet and Firewire.
Following are the features of USB port or USB connection:
• There are different versions of USB. USB 2.0 supports 480Mbps, USB 3.0 supports 5 Gbps and USB 3.1 supports 10 Gbps.
• USB controller is needed to control bus and data transfer.
• Support cable length upto 5 meters.
• Supports upto 127 devices.
• Supports peer to peer topology.
• Power supply to external devices is 500mA/5V(MAX.)
• Applications: Keyboard, Mouse, Monitor, Hub, Audio, digital camera, scanner etc.
Following are the features of Ethernet port based connection:
• Normal ethernet supports 100 Mbps and gigabit ethernet supports 1 Gbps, 10 Gbps and even 100 Gbps.
• Based on IEEE 802.3 specifications.
• Commonly available forms are 10 BASE-T, 100 BASE-TX and 1000 BASE-T.
• USed to share internet connection among multiple devices, would like to take benefits of firewall to secure the network etc.
Following are the features of Firewire connection:
• Based on IEEE 1394.
• Supports data rates 100 Mbps, 200 Mbps and 400 Mbps. Latest Firewire supports even 3Gbps and 6Gbps.
• It works without any control i.e. devices communicate in peer to peer mode.
• Supports cable length of 4.5 meters.
• Supports upto 63 devices/
• Supports peer to peer topology
