Where is a hub specified in the OSI model?
Answer: Option B
Hubs regenerate electrical signals, which are specified at the Physical layer.

|Physical layer because it is the layer by which physically two devices are connected with a wire.|

|Physical layer, because hub is not an intelligence device, it is use in connect some devices in physical layer. It is use for broadcasting in lan.|

|Physical layer because it is the layer which two devices connected with a cable.|

|Physical layer because in Hub only broadcast of package is possible.|

|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).|

|What is a IP address?|
|Amit Gupta said: (Dec 19, 2014)|
|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?|
|Abdul Basit said: (Jan 18, 2015)|
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.

|For hub is there no intelligence to it. Tell me please.|
|Yusuf Mai said: (Aug 13, 2017)|
|It is used in transport layer.|

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