Difference between a HUB and a Switch

HUB

hub

1. The data sent are sent on all ports to devices that decode the frame header to see if they are the recipients.
2. The total bandwidth is limited to speed hub. A 100 base-T hub provides 100 Mbps of bandwidth shared between all PCs, regardless of the number of ports.
3. Not compatible “half-duplex. A port 100 Mbps allows just one link to 100 Mbps.

SWITCH

switch

1. The data sent from one computer to another are only received by the addressee. If another computer sends data to the printer, they are completely separated; the two communications can be done simultaneously.
2. The bandwidth is determined by the number of ports. i.e., A 100 Mbps 8-Port Switch can handle up to 800 Mbps half duplex, dual full duplex.
3. They are compatible full-duplex, doubling the speed of each port, 100 Mbps to 200 Mbps for Ethernet 100 Base T.
