| 24643 | 2001-11-16 09:12:00 | I just wondering about USB HUB. Exactly what is USB HUB? What is the different between USB HUB and 10/100 SWITCH HUB? is this mean that you don't need Network card for USB HUB? or it just a hub that use USB to power up? What is the performance different between those hubs? Thanks in advance! YB |

| 24644 | 2001-11-16 11:09:00 | Hi, For starters allow me to distinguish the difference between a switch and a hub. A 100mbps hub, for example delivers 100mbps bandwidth across all connected users equally, so if you have four computers connected they get 25mbps each. A switch delivers the full 100mbps to each user, so if you have four computers connected to it they all get 100mbps, consequently, switches are more expensive. A USB hub uses the universal serial bus interface instead of ethernet/RJ-45. I would expect a usb switch to exist, yet I have not seen any for sale. My advice is to steer clear of usb, as the cabling is very costly, and when I priced it for my own network, even the added costs of NIC's and a switch made it cheaper. Usb is better for PC's which require only very small bandwidth, and are very close together. A 10/100 card, hub or switch is a device that can be used at either 10mbps or 100mbps. Also note that mbps is Mega Bits per second, not megabytes... there are 8 bits in a byte, meaning that 100mbps is 12 Megabytes per second. Have I covered everything? |
