This is done by using MAC addresses , or the hardware address of a network adapter. A table of MAC addresses is maintained by a switch. There are three types of switching techniques, namely: Circuit Switching, Packet switching, and Message switching. Routing is the process of connecting various networks simultaneously.
Routing, therefore, happens in the network layer. Routing process involves setting a path for data packets to move in a network or across multiple networks. A routing device maintains a table called Routing Table. This table is used to determine the route to the destination network.
If there are multiple conductors, the electricity would go through the conductor having the path of least resistance. Similarly, a router tries to send data packets, possibly through the shortest path in the connection of various networks. By now, reading the definitions of the terms might have brought in a sense of understanding that how routing and switching are fundamentally different.
However, the differences between the two can be more clearly understood from the following table:. It works in the network layer. It works in the data link layer. Used by LAN only. Data is send as packets over by a Router. It can decide which computer is the message intended for and send the message directly to the right computer. The efficiency of the switch can be improved by providing a faster network speed.

Reliability Business crises come in all varieties - from power failures to hurricanes and everything in between. Your organization's ability to maintain normal operations during a crisis may rely on the health of your network. A network designed with reliability and redundancy will provide the reassurance you need that your business will continue. Contact a Cisco partner to learn more and get exactly what you need.

Through your network. Where is your company's software? On the network. How does an important presentation get shared by multiple members of your team? Via the network. What carries critical messages to your employees and partners?
Your network. Though they look quite similar, routers and switches perform very different functions in a network: Switches are used to connect multiple devices on the same network within a building or campus.
For example, a switch can connect your computers, printers and servers, creating a network of shared resources. The switch would serve as a controller, allowing the various devices to share information and talk to each other. Through information sharing and resource allocation, switches save you money and increase productivity. There are two basic types of switches: managed and unmanaged. An unmanaged switch works out of the box and does not allow you to make changes.
Home-networking equipment often will have unmanaged switches. A managed switch allows you access to program it. This provides greater flexibility because the switch can be monitored and adjusted locally or remotely to give you control on how traffic travels over the network and who has access to your network.
Routers are used to tie multiple networks together. The term layer 3 switch often is used interchangeably with router , but switch is really a general term without a rigorous technical definition.
In marketing usage, it is generally optimized for Ethernet LAN interfaces and may not have other physical interface types. A router is a networking device that connects computer networks, for example, connecting a home network with the Internet. Routers are the workhorses that transfer packets of data between networks to establish and sustain communication between two nodes in an internetwork.
Routers operate at Layer 3 network layer of the OSI model ; a router uses the destination IP address in a data packet to determine where to forward the packet.
A network switch connects devices together on a single computer network. A switch is also called switching hub, bridging hub, or MAC bridge. Switches use MAC addresses to forward data to the correct destination. A switch is considered a Layer 2 device, operating at the data link layer; switches use packet switching to receive, process and forward data. Network hubs — also called repeaters — are even less advanced that switches; while a hub broadcasts the same data to all its ports, a network switch forwards data only to those devices that the data is intended for.
Network hubs do not manage any traffic coming through them; they only broadcast — or repeat — packets from an incoming port to all other ports.
A router is a more sophisticated device than a switch. Routers serve as intermediate destinations for network traffic. In addition, routers often perform network address translation NAT , which allows all devices on a subnetwork e. Finally, routers that include built-in firewalls improve the network's security.
