A router is a more sophisticated network device than either a switch or a hub. Like hubs and switches, network routers are typically small, box-like pieces of equipment that multiple computers can connect to. Each features a number of "ports" the front or back that provide the connection points for these computers, a connection for electric power, and a number of LED lights to display device status. While routers, hubs and switches all share similiar physical appearance, routers differ substantially in their inner workings.
Traditional routers are designed to join multiple area networks (LANs and WANs). On the Internet or on a large corporate network, for example, routers serve as intermediate destinations for network traffic. These routers receive TCP/IP packets, look inside each packet to identify the source and target IP addresses, then forward these packets as needed to ensure the data reaches its final destination.
Routers for home networks (often called broadband routers) also can join multiple networks. These routers are designed specifically to join the home (LAN) to the Internet (WAN) for the purpose of Internet connection sharing. In contrast, neither hubs nor switches are capable of joining multiple networks or sharing an Internet connection. A home network with only hubs and switches must designate one computer as the gateway to the Internet, and that device must possess two network adapters for sharing, one for the home LAN and one for the Internet WAN. With a router, all home computers connect to the router equally, and it performs the equivalent gateway functions.
Additionally, broadband routers contain several features beyond those of traditional routers. Broadband routers provide DHCP server and proxy support, for example. Most of these routers also offer integrated firewalls. Finally, wired Ethernet broadband routers typically incorporate a built-in Ethernet switch. These routers allow several hubs or switches to be connected to them, as a means to expand the local network to accomodate more Ethernet devices.
In home networking, hubs and switches technically exist only for wired networks. Wi-Fi wireless routers incorporate a built-in access point that is roughly equivalent to a wired switch.

router:a worker who routes shipments for distribution and delivery
Hub:the central part of a car wheel (or fan or propeller etc) through which the shaft or axle passes

In short the Router is layer three device used to connect different networks and hub is a layer one device.

Router: A router “directs traffic” at the gateway of two networks. In the case of a home network, it provides the connection between all of the devices in your network to each other and to the Internet. The router would typically be connected to the cable modem at one end, and the devices in a home network on the other end. Those devices could include computers, network printers and wireless access points.
Hub: A hub is a device that allows sharing of a connection to multiple devices. It differs from a router in that a hub takes one connection and spreads it out evenly among the devices attached to it (often impacting transfer speeds negatively), while a router provides full-speed connectivity to each device as needed – directing traffic rather than indiscriminately splitting the bandwidth available to all devices connected to it. A hub cannot be used for sharing a single Internet connection across multiple PCs.

Router:
A router is a device in computer networking that forwards data packets to their destinations, based on their addresses. The work a router does it called routing, which is somewhat like switching, but a router is different from a switch. The latter is simply a device to connect machines to form a LAN.
Hub:
A hub is used in a wired network to connect Ethernet cables from a number of devices together. The hub allows each device to talk to the others. (Hubs aren't used in networks with only wireless connections, since network devices such as routers and adapters communicate directly with one another, with nothing in between.)
Hubs are such simple devices — they require no configuration, and have no manuals — that their function is now included in other devices such as routers and modems.
