difference between router and switch

The difference between router and switch is what every network enthusiast must know. But how do a router and a switch work? Both the router and the switches enhance data communication.

Routing enables the whole network while switching connects a single network with individual computers. The role of routers and switches are similar, but router manages data communication on a larger scale.

This blog will focus on the difference between routing and switching in detail.

What is Routing?

Routing or Network Routing is the process of finding a path between one or more networks. Routing is available for any type of network, like telephones and public transportation. In packet-switching networking, the router chooses the path for IP packets to move to their destination. The routing decisions are in the hands of specialized network hardware called Routers.

What is the purpose of Routing?

The purpose of routing is to enclose data that helps to communicate beyond a network, to choose the paths that control traffic to final networks, to transform a URL name into an IP address, to supply safe Internet file transfer, and to advance traffic based on MAC addresses.

What are the main Routing protocols?

According to the network, a protocol is a method to format data in an easy language so that every computer can understand it. The role of a routing protocol is to identify or announce safe networking paths. 

There are various protocols to find a way through data networks, and they are:

  • Internet Protocol or IP

The Internet Protocol identifies the origin and destination of each data packet. Routers inspect the IP headers of each packet and decide where to send them.

  • Broader Gateway Protocol or BGP

BGP checks which network will control which IP address. BGP comes under dynamic routing protocol. The sizeable networks that make this BGP announcement are called autonomous systems.

  • OSPF or Open Shortest Path First

OSPF selects the shortest path for sending network packets.

  • RIP or Routing Information Protocol

RIP searches for the shortest path using hop count to connect from one network to another. Hop count is the number of packets one must pass through on the way.

How does Routing work?

The router helps to connect internet-based devices like PCs, tablets, smartphones, thermostats, smart TVs, etc.. These devices can form a network where communication occurs through the same network. The router ensures fast and smooth network transfer. Different types of data use distinct bandwidths. 

Here are the steps of working on a routing process:

  1. The router gets the packets and reads the headers of the packets.
  2. With the help of headers, it finds the destination of the packets.
  3. After searching the routing tables, it decides the destination of the packets.
  4. Numerous routers route a packet on their way to the final port of call.
  5. Two types of routers are there- dynamic and static.
  6. Static Router remains constant but the tables of the dynamic Router changes numerous routing protocols.
  7. For better enhancement, dynamic routers are more beneficial than static ones.

What are Switches?

Switches allow networks to connect and exchange data packets to let them communicate. Switches can be in a hardware or software form. The operation of the switches occurs with the help of an OSI model. Switches check the Media access control or MAC address of each message and decide where to send the incoming message.

What is the purpose of Switches?

Switches maintain the transfer of information between distinct endpoints. This is the main purpose of the switches, but there are various other motives, too. 

Here is a list of the aims of the network switches-

  • Switches structure the network devices into modern data networks and transfer large traffic in the networks providing telecommunications.
  • Network Switches offer binary communication, link network segments, enhance network performance, and use bandwidth effectively.
  • Network switches offer wired connections to PCs, wireless APs, printers, industrial machinery, and IoT devices like card entry systems.
  • Network switches work with power over Ethernet technology that supplies 100 watts of power to support network connectivity.
  • Network switches can also collect data from IoT devices. Artificial Intelligence and Machine Learning then utilize these data to improve smarter surroundings.

What are the types of switches?

There are almost seven types of networking switches. Here is a list of all seven:

  • Virtual Switches

They are the software-only switches embodied inside the VM hosting environment.

  • Routing Switches

Routing Switches link LAN. They perform MAC-based Layer 2 switching, functions at OSI Layer 3, and collect traffic based on the IP address in individual packets.

  • Managed Switches

It allows adjustment of each port on the switch that includes monitoring and configuration.

  • Unmanaged Switches

Unmanaged switches allow Ethernet devices to pass data using auto-negotiation that determines data rates. This is a dynamic configuration.

  • Smart Switches

Smart Switches ensure more control over data transmission. They are also called partially managed switches.

  • Stackable Switches

Stackable switches are dynamic switches. They are joined with each other via the backplane cable interface and structure into a single logical switch.

  • Modular Switches

Modular Switches are switch cards that are installed into sizable, and fixed-form factor chassis. Modular Switches ensure more flexibility and upgradeability.

How does a Network Switch work?

The major role of switches is to transform data to enhance data communication. But not every switch needs to use the same layout. Many layouts work with different arrays of hardware and software. 

Here are the steps on how a network switch works:

  1. When a device gets attached to the network switch, it records its MAC or Media Access control address, which is present on the Network Interface Card [NIC] of the device.
  2. The NIC is connected to the Ethernet Cable, and the Cable is further connected to the switch.
  3. The network switch utilizes the MAC address to check which device outgoing packets are sent and decides the location of the incoming packets.
  4. The MAC address recognizes the physical device and keeps it constant, while layer 3 of the IP address can change.
  5. When the packet enters a switch, it examines the header to match it with the destination address.
  6. It sends these packets to their destination. Switches offer full-duplex functionality to avoid packet collision.

What is the difference between Router and Switch?

We have learned the role of routers and switches individually. Now, let us find the difference between routing and switching in detail-

  • The router is a layer 3 device, and the switches are the layer 2 device on the OSI model.
  • The router transfers data between 2+ computers, while the switches ensure resource sharing by connecting various devices on a single LAN.
  • To determine the packet destination, the router surveys the IP address of the packet while the switches check the MAC address.
  • Routers use data packets, and switches use data frames.
  • To direct data across large networks, the routers use routing algorithms, but switches do not.
  • Switches need wired connections to work, but routers can work with both wired and wireless connections.
  • Routers give access to all ports to have their domain, but switches allow only one broadcast domain.
  • Routers use full-duplex mode, and network switch uses both full and half-duplex modes.
  • Routers can perform Network Address Translation or NAT and Port Address Translation or PAT, while Network switches perform neither NAT nor PAT.
  • Routers do not need an internet connection, while network switches need internet connections.
  • There are two forms of routing- adaptive and non-adaptive while network switches are of three forms – circuit, packet, and message.

What are the similarities between Routing and Switching?

We have seen the difference between routing and switching, but they have a few similarities, too. 

Here are the similarities between routing and switching:

  1. Routing and Switching come under computer networking. Both these processes are for connecting devices.
  2. Routing and Switching offer modern solutions network connectivity solutions.
  3. Routing and Switching are possible with home connections, like homes, small offices, etc.
  4. Routers and switches appear similar, and both are light in weight.
  5. The number of ports in routers and switches may vary, but both use ports.

Switches in Networking

It’s these technical terms that scare me, I’ve heard so many say. Well, can’t lie, been there done that, especially when these big IT guys start name-dropping. But it is actually really important to be aware of the topology of the domain you choose to be a part of.
For instance, Networking is one very popular domain of IT.
In this blog we shall, read more about switches as vital pieces of equipment for Networking.
Before we jump on to studying switches, it’s very important for us to glance over the entire topology of Networking to develop a better understanding. 

Topology of Networking:

What is a Topology?

Topology in general refers to the way in which all the constituent parts are interrelated or arranged.
When we talk of Network Topology, it refers to the logical and physical arrangement of nodes and connections existing in any network. 

Nodes: The nodes are inclusive of all devices such as switches, routers and software with switch and router features.

We read about the different kinds of devices that are included in nodes, often people tend to get confused amongst routers and switches. We shall have a look at the differences between routers and switches.

Router Vs Switch :

The most basic difference between these two is that Routers suffice for all working in homes , small offices, without feeling a need for switches.
Whereas we do need a switch, when we need to facilitate large amounts of Ethernet ports. 

What is a Switch in Networking?

Switches in Networking

A switch is a network device which is employed to create segments in the networks into different subnetworks which are defined as subnets or LAN segments. It has the responsibility of filtering and forwarding the packets between LAN segments based on the MAC address.

The other of its functions are as follows: 

  • It performs error checking before it begins to forward data. 
  • It operates in Data Link Layer in OSI Model. 
  • It is capable of transferring the data only to the device that has been addressed.
  • It operates in full duplex mode. 
  • It allocates each LAN segment to limited bandwidth.

This diagram will help you understand the switch and its role to an extent.

Switches in Networking

How Switch in Networking Works step by step?

We had a look at the roles of a switch. Let’s have a look at the working of a switch.
The work of a switch starts when the source wants to send the data packet to the destination, packet first enters the switch and the switch interprets it by reading its header and finding the MAC address of the destination to identify the device. It further sends the packet out through the appropriate ports that leads to the destination device.

The Switch establishes a temporary connection between the source and the destination for establishing communication and terminating the connection once the conversation is done.
It also offers full bandwidth to network traffic going to and from a device at the same time to facilitate no or really less collision. 

Switches in Networking

There are many switching techniques that are employed to decide the best route for data transmission between source and destination. These techniques are classified into three categories: 

  1. Circuit Switching 
  2. Message Switching 
  3. Packet Switching 
Switches in Networking

Let’s try to understand these switching techniques a little better:
Circuit Switching: 

Circuit Switching is a network switching technique for implementing a telecommunications network in which two network nodes create a devoted communications channel (circuit) by the means of the network before the nodes may be able to communicate.


Message Switching: 

Message switching is a network switching technique where data is routed completely right from the source node to the destination node, one single hope at a time. Whilst the message routing is being carried out, each of the intermediate switches in the network stores the entire message.

Packet Switching: 

Packet Switching refers to the transfer of small pieces of data across various networks. These data chunks are also known as packets. These packets or chunks enable faster and more efficient data transfer. 

There are many questions that surround the topic; a Switch. Very common yet recurring questions, like, what is a layer 2 switch, what is a layer 3 switch. What are managed and unmanaged switches ? Let’s have a look at these questions are tey to understand them completely. 

What is meant by layer 2 switch and a Layer 3 switch?

The maximum number of switches are layer 2 switches. The layer two switches forward data based upon the destination MAC address. 

Whereas layer 3 switches forward data that is based upon the destination IP address.

What is an unmanaged Switch and how does it differ from a managed Switch?

An unmanaged switch is designed to simply create more number of Ethernet ports on a LAN, so as to let more number of local devices access the internet.
A managed switch also tends to fulfil the same function but for way larger networks. It also offers network administrators increased control over how the traffic is going to be prioritised.

FAQ:

1. What are the types of networking?

The most common types of networking are: 1. KVM Switch 2. Managed Switch 3. Unmanaged Switch 4. Smart Switch 5. PoE Switch

2. What is the purpose of a switch?

The purpose of a switch is very important as the switches are referred to as the building blocks of any network. They are vital in connecting multiple devices on the same networks within a building or a campus. The devices they connect are computers, wireless access points, printers and servers. The switches enable the connected devices to share information and communicate as well.

3. What are the three functions of a switch?

The basic three functions of a switch are: 1. Learning 2. Forwarding 3. Preventing layer 2 loops.

4. What is the benefit of a switch?

The primary benefit of a switch is that it increases the available bandwidth of any network.

Conclusion:

The role of a switch is actually crucial. It forms an integral part of the networking topology. It faciliates the connection of maximum number of devices. Switches in Networking are very important as they aid the increase of the existing bandwidth of any given network.
