Store-And-Forward Switching is a kind of #switching mode that waits to receive the entire frame before forwarding. It will first read such a frame, then pass it to cyclic redundancy check (CRC). If the CRC is bad, the frame will be simply discarded, which could causes some latency but minimises errors at the same time.

Switch
It has three primary frame switching modes: Cut-Through Switching#, Store-And-Forward Switching# and Fragment-Free Switching#. All of them will check the destination and source Media Access Control Address (MAC), then check against the table, which contains entries that map Switch port to a particular MAC, maintained by Switch. It will place an entry for the source MAC corresponds to the switch port where the frame came (if it hasn’t done so before), and check whether there is an entry for the destination MAC. If there is not, it will flood (send frames to all other ports) the frames, and waits for the response. If there is such a response coming from one of the switch’s port, it will map that port to the destination MAC and immediately forward the packet to the port. Otherwise, depending on whether the destination MAC is in the same network segment, it either doesn’t forward the packet or forward the packet to the port specified in the table (filtering).
