What is the main difference between Data Switch, Hub and Router?

The big difference between Hub vs Switch  in the method in which frames are being delivered. In a hub, a frame is passed along or "broadcast" to every one of its ports.  The hub has no way of distinguishing which port a frame should be sent to. A switch, however, keeps a record of the MAC addresses of all the devices connected to it. With this information, a switch can identify which system is sitting on which port. So when a frame is received, it knows exactly which port to send it to,

Routers are completely different devices. Where a hub or switch is concerned with transmitting frames, a router's job, as its name implies, is to route packets to other networks until that packet ultimately reaches its destination.
