Term
What is store-and-forward switching technology?
Definition
The switch takes in a frame and does a CRC before forwarding the frame out.
Term
What are two types of cut-through switching and what are the differences?
Definition
Fast-forward switching - immediately forwards a packet after reading the destiniation address

Fragment-free switching -- switch stores the first 64 bytes of the frame before forwarding. This prevents most collisions.
Term
What is the difference between symmetric and asymmetric switching?
Definition
Symmetric is between ports of the same bandwidth and asymmetric is different bandwidths.
Term
What is port-based vs shared memory buffering?
Definition
Port based allocates a buffer to each port. Shared allocates memory for all ports to use.
Term

Definition
Increases the size of the terminal history to the last 50 commands from the default of 10 commands.
