As a result, all the computers receive the traffic, even if it is not for them. A switch is more intelligent than a hub. As a hub, a switch is the connection point for the computers and other devices in a network.
However, a switch is more efficient at passing along traffic. It records the addresses of the computers connected to it in a table. When traffic comes through, the switch reads the destination address and sends that traffic to the appropriate computer rather than sending it to all the connected computers. If the destination address is not in the table, the switch sends the traffic to all the connected computers.
A router is the most intelligent of the three hardware devices. It is typically a small computing device designed specifically to understand, manipulate, and direct traffic. Routers include a user interface so that you can tell them where to direct the traffic.
The primary function of a traditional router is to connect two or more networks or network segments in a very large network and direct traffic between them. For instance, a business might use a router to manage the connection between its local network and the Internet. To distribute the traffic to the computers in the local network, the business could connect the router to a switch or hub. While traditional routers are still available, most small business and home office routers today combine the functionality of a router and the functionality of a switch or hub in a single unit.
In the full-duplex mode, however, the switch transmits data. A switch filters the frames to provide the redirected frame only to the dedicated device.
On the other hand, the filtering concept is not used in the hub, and a frame is transmitted to each port. To eliminate the problem of switching loops, the switch uses Spanning Tree Protocol. The hub, however, is unable to avoid switching loops. Hub and switch are Networking devices that provide a mechanism for connecting several devices to communicate. The hub is, however, physical, while the switch operates the data connection layer. A switch overcomes the restrictions of the hub and provides the frame, hardware address, and loop avoidance intelligent transmission.

In network equipment and devices, data is usually transmitted in the form of a frame. When a frame is received, it is amplified and then transmitted to the port of the destination PC Personal Computer.
The big difference between hub and switch is 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. It doesn't matter that the frame is only destined for one port.
The hub has no way of distinguishing which port a frame should be sent to. With this information, a network 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, without significantly increasing network response times. So regardless of the number of PCs transmitting, users will always have access to the maximum amount of bandwidth. Unlike an Ethernet hub or switch that is concerned with transmitting frames, a router is to route packets to other networks until that packet ultimately reaches its destination.
