Switch Internal Processing $($match the processing method to its definition$)$

$1-$Store and forward

$2-$Fragment$-$free

$3-$Cut$-$through

a$.$The switch fully receives all bits in the frame before forwarding the frame. This allows the switch to check the FCS before forwarding the frame.

b$.$The switch forwards the frame as soon as it can. This reduces latency but does not allow the switch to discard frames that fail the FCS check.

c$.$The switch forwards the frame after receiving the first $64$ bytes of the frame, thereby avoiding forwarding frames that were errored due to a collision
