difference between Hub and SwitchQ?

hi.. every one

most of the times i see that people use this kind of notation: Hub/Switch

whyQ Isnt there any difference between Hub or a SwitchQ

as far as I know.. Hub is used to group multiple computers in a network. rightQ

When you send packets to a hub, the hub will is going to repeat that data to all devices connected to it (not just the intended destination). A switch is the exact opposite. It will connect to the destination device based on the packet's header and send it to that device and that device only.

Short answer: Switches = Less traffic, Better for larger networks, More expensive Hubs = Mass traffic, More collisions, Small networks only, and Cheap

Or so is my understanding ;).

This is a bit off topic, but you should learn about Transparent Learning Bridges. It will help your overall knowledge of routing and terminology associated with it, ie: collisions, etc..

Also, this knolwedge is critical in knowing what ARP Spoofing really is, and what cache and routing tables are.

And if you're familiar with the OSI/ISO Model, you should understand that:

• Hubs operate at ISO Layer 1 - Physical Layer
• Switches operate at ISO Layer 2 - Data Link Layer
• Routers operate at ISO Layer 3 - Network Layer
