    A Physical address is a 48-bit flat address burned into the ROM of the NIC card which is a Layer1 device of the OSI model. This iis divided into 24-bit vendor code and 24-bit serial address. This is unique for each system and cannot be changed.

    A Logical address is a 32- bit address assigned to each system in a network. This works in Layer-3 of OSI Model. This would be generally the IP address.

    Hub is a broadcasting device which may increase collision domain but switch is based on filter and forwarding and reduce collision domain.

    Hub is layer 1 device, work in physical layer and the communication between device are half duplex, all the device exist in on collision domain, switch is L2 device and every port a collision domain has concept of Mac address table, (cash)
