Main Difference

The difference between router and switch is that router is three network layer that direct data between home computers whereas a switch is two network layer that allows connection for multiple devices.

Router vs. Switch

There are many computer networking devices that allow one or more computer share network and data. Two most important type of network devices are router and switches they work for the same purpose, but they are not same, the router is three network layer that direct data between home computers whereas a switch is two network layer that allows connection for multiple devices. Routers switches and hubs all work for the same purpose that is the transmission of data from one computer to another computer. Two or more logical subnets are connected by routers, and one to one mapping is not necessary for the router. There are layer 3 switches in the router. Switches are optimized for Ethernet. A device that connects computer networks is known as a router the example of the router is connecting a home network with internet. A single computer network is connected by using switches. Switching hub is mostly used for the switch. There are other terms such as bridging hub and MAC Bridge that is used in place of switching hub. The switch is a 2 layer device that is operating at the data link later. Packets are used to switching and to receive the process. The packets of data between networks are transferred using router that is the workhorses. These are used to establish and sustain communication between two nodes in an internet work. The 3 network later is where the router operates. An IP address is used as a destination in a data packet.

What is a Router?

A device that connects computer networks is known as a router the example of the router is connecting a home network with internet. The packets of data between networks are transferred using a router that is the workhorses. These are used to establish and sustain communication between two nodes in an internet work. The 3 network later is where the router operates. An IP address is used as a destination in a data packet. There are many routing algorithms in networking; the classification is based on the building and modification of routing tables. There are two routing algorithms that are static routing and dynamic routing. In static routing, routers are configured manually whereas in dynamic routing the routing routers are configured automatically. Most of the people like to use dynamic routing in place of static routing as there are many issues in static routing one of the main issues are that link fails the system sometimes to connect whereas many such problems are overcome in dynamic routing. Routing is one of the most important concepts in networking as it the process of transferring the packets from one network to other. The router in routing system plays a very important in networking as it has destination device address, it knows neighbor routers for learning about remote networks, it possible routes to all remote networks. Dynamic routing the routing routers are configured automatically. Dynamic routing alters the routing information according to the altering network circumstances by routing the update messages. When the network is changed in dynamic routing, the update message is displayed. This message pervades the network that enables the router to change their routing tables. The changes made in dynamic routing is automatic as there is no need to set the router manually. Extra resources are required for the dynamic routing. In static routing, routers are configured manually. No change is made in routing table unless the network administrator changes router manually. When the traffic is manually predictable, we can use static routing. The big advantages of static routing are that it is very easy to implement as compared to dynamic routing. There is a need of complex routing protocols in dynamic routing that are not needed in dynamic routing. Static routing systems can not react to network changes that are why routing decisions are not made by current topology. The changes made in static routing are very easy to understand, and you can make changes easily. But static routing is considered to be inappropriate for large changing networks. Static routing is non-adaptive routing that enables pre-computed route. Dynamic routing is also known as adaptive routing. Changes are made in routing in dynamic routing to change topology. Dynamic routes are the routes on which dynamic routing is done. There is always a slack between the period that a network changes and when all network changes that time is known convergence time. That time must be shorter.

What is a Switch?

A single computer network is connected by using switches. Switching hub is mostly used for the switch. There are other terms such as bridging hub and MAC Bridge that is used in place of switching hub. The switch is a 2 layer device that is operating at the data link later. Packets are used to switching and to receive the process. LAN is a local area network that links network devices. Local area network is for personal computers, for example, there is an office, and there are many computers these computers are lined, and the communication is done using a Local area network. The workstations that are connected using LAN can share data, and this network is connected with wires. The rate of transfer of data using of local area network is very fast. But the only problem is that the limitation is very limited. LAN can only cover a small geographical area, and it is owned by one person. LAN can use in office, building, home, schools and hospitals. One of the biggest advantage of LAN it is very easy to make and maintain. Twisted pair cable and coaxial cable is used in the making of Local area network.

Key Differences

  1. The router is three network layer that direct data between home computer whereas Switch is two network layer that allows connection for multiple devices.
  2. The router is a three layer network whereas a switch is two layer network.
  3. The router has more speed than switch whereas switch has less speed than the router
  4. The router can perform network address transmission whereas switch cannot perform network address transmission.
