Switch
Generally called as two layer switch . it performs on physical and data link layers. It is a bridge it has many ports that allow better performance. Since it is a bridge with many ports it allows allocating a unique port to each station hence each station has its own independent identity. It makes bridge performance better as it has a buffer to hold the frames for processing also it has a switching path that forwards the frame faster.
