3. Collision domain is a network segment with two or more devices sharing the same bandwidth.
4. A hub network is a typical example of this type of technology
5. Each port on a switch is actually its own collision domain, you can make a much better Ethernet LAN network just by replacing your hubs with switches2
6.
7. Recording the port on which the MAC address was received. In this way, the bridge or switch learns which addresses belong to the devices connected to each port.
15. Switch caches the MAC address of station A to port E0 by learning the source address of data frames.
16.
17. Switch caches the MAC address of station D to port E3 by learning the source address of data frames.

23. When a switch is turned on, the spanning-tree algorithm is used to identify the root bridge. BPDUs are sent out with the Bridge ID (BID).
24. The BID consists of a bridge priority that defaults to 32768 and the switch base MAC address.
25. When a switch first starts up, it assumes it is the root switch and sends BPDUs. These BPDUs contain BID.
26. All bridges see these and decide that the bridge with the smallest BID value will be the root bridge.

29. The default mode is User EXEC mode, which ends in a greater-than character (>).
30. The commands available in User EXEC mode are limited to those that change terminal settings, perform basic tests, and display system information.
31. The enable command is used to change from User EXEC mode to Privileged EXEC mode, which ends in a pound-sign character (#).
32.
33. To manage the switch via Telnet or other management software
34. To configure the switch with different VLANs and other network functions
35. See the default IP configuration = show IP commandConfigure IP Address sw1(config-if)#interface vlan 1 sw1(config-if)#ip address 10.0.0.1 255.0.0.0 sw1(config-if)#no shut sw1(config-if)#exit sw1(config)ip default-gateway 10.0.0.254 18
