Study Notes
Hubs
- Hubs are multi-port repeaters that broadcast data to all connected devices.
- When a data frame is transmitted to a hub, it is immediately re-sent to all connected links.
- Hubs operate on Layer 2 of the OSI model.
Switches
- Switches are more sophisticated than hubs, determining whether data remains on a LAN or is transferred to a specific device.
- Switches forward data based on the destination hardware (MAC) address.
Extranets
- Extranets provide secure access to company data for individuals outside the organization.
- Examples include providing access to external suppliers or contractors.
