Physical Layer---------> HR (Hub and Repeater).
Data link Layer---------> SB (Switches and Bridges)
Network Layer-----------> Routers.

Hub simply replicates the incoming network data to all outgoing ports. It has no intelligence like switch (layer 2 and layer 3) to filter out traffic using mac address (layer 2 switch) or by ip address (layer 3 switch i.e. router).

An IP address is a logical address and it is a 32 bit address. IP address specify a user on the network, and it is a temporary address.

Why the port is used?

@Mr. Yoga:
Ports are used in transport layer (TCP, UDP, SCTP). Since transport layer is responsible for end to end communication, it must identify the application (or process) who initiated the request.
