The hosts transmit a jam signal to ensure that all hosts on the network are aware that a collision has occurred.
Because they are operating in full-duplex mode, the hosts resume listening for traffic in preparation for sending future messages.
Because the hub will temporarily block traffic from one of the hosts, that host will be allowed to-transmit once the wire is clear.
Hosts A and C are assigned shorter back off values to provide them priority to access the media for retransmission.
After the back off period of a host, the host checks to determine if the line is idle before retransmitting.
Spanning Tree Protocol is disabled.
All switch ports are assigned to VLAN1.
The flash directory contains the IOS image.
VLAN1 is configured with a management IP address.
All interfaces are set to auto-negotiation of speed and duplex.

SW1 connects via two Fast-Ethernet links to reach the root switch.

A cost of 38 is the value that is being advertised out port 26 on the upstream switch, which is closer to the root switch.
The root switch is advertising a cost of 38, which is lower than any other switch that participates in the VLAN0001 spanning-tree domain.
SW1 connects via a Fast-Ethernet link to an upstream switch that in turn is directly connected to the root switch via a Gigabit Ethernet link.
