Both of these are connecting devices that help in networking. We use a router for settling on the shortest path through which any given packet can easily achieve its intended destination. There is a difference between router and switch. A router’s main objective is to establish a connection between various networks in a simultaneous manner. Also, it works on the network layer. A switch’s main objective is to establish a simultaneous connection among various devices. It basically functions on the data link layer. In this article, we will discuss the difference between router and switch in further detail. Read ahead to know more.
What is a Router?
A router is a device for computer networking that serves two of the main functions: (1) the creation and maintenance of a local area network (2) the management of data that enters and leaves a network along with the data that moves inside of the network.
In other words, a router assists its users in handling various networks, and it also routes the network traffic present between them. In the case of a home network, a router establishes a connection to the private LAN and establishes another one to the Internet. Also, various routers have various built-in switches. These switches allow a user to connect various wired devices.
What is a Switch?
A network switch is basically a computer networking device that helps in connecting multiple devices on one computer network. One can also use it for routing the information into an electronic form of data (that transmits over various networks). We can also call switches bridging devices because the process of establishing a link between network segments is known as bridging.
Difference Between Router and Switch
| Parameters | Router | Switch |
| Operating Layer | A typical router can easily operate at the third layer (Network) in an OSI model. | The switches in a network operate at the second layer (Data Link Layer) in an OSI model. |
| Services Offered | A router can easily offer QoS, NetFlow, and NAT services. | A switch does not offer any such services. |
| Maintenance of Addresses | A router stores IP addresses in its routing table and maintains its own address. | A switch stores MAC addresses in its lookup table and maintains its own address. But in this case, a switch can easily learn the MAC addresses. |
| Ports | It is a networking device with 2/4/8 ports. | It is a type of multi-port bridge with 24/48 ports. |
| Duplex | It is less duplex in nature. | It is full-duplex in nature. Thus, no collision occurs here. |
| NAT | It can easily perform NAT. | It cannot perform NAT. |
| Speed Limit | It has a speed limit of about 1-10 Mbps (Megabytes per second) for wireless connection and 100 Mbps in case of a wired connection. | It has a speed limit of about 10/100 Mbps. |
| Routing Decision | A router helps its users in taking a faster routing decision. | A switch will more likely take a routing decision which is way more complex. |
| Broadcast Domain | Every port in a router contains a broadcasting domain of its own. | A switch contains a broadcasting domain of its own except the implemented VLAN. |
| Faster Performance | In the case of various network environments (like WAN/MAN), a router will work much faster than the switches. | A switch can work comparatively faster than a router when deployed in a LAN environment. |
| Type of Addresses | The operations of a router revolve around the IP addresses. | In the case of switches, they work with the MAC addresses. It is because these operate within a single network only. |
| Wiring of Connections | It can easily work with both- wireless as well as wired situations of a network. | The uses of a switch are confined to only wired network connections. |

FAQs
Just as a switch connects multiple devices to create a network, a router connects multiple switches, and their respective networks, to form an even larger network. These networks may be in a single location or across multiple locations. When building a small business network, you will need one or more routers.
Do I need both a router and a switch? ›
In practice, what this means is that routers are necessary for an Internet connection, while switches are only used for interconnecting devices. Homes and small offices need routers for Internet access, but most do not need a network switch, unless they require a large amount of Ethernet* ports.
Why do we use a switch instead of a router? ›
There is a difference between router and switch. A router's main objective is to establish a connection between various networks in a simultaneous manner. Also, it works on the network layer. A switch's main objective is to establish a simultaneous connection among various devices.
How does a switch work with a router? ›
Your network switch connects to the router through one of the ports on the router, extending the number of devices in your small office network, such as desktop computers, printers, laptops, etc. that have a wired connection to the internet.
How many switches can be connected to a router? ›
Some routers have a limit of four switches, while others can support up to 16. If you need help connecting switches to your router, make sure you consult your router's manual or the manufacturer.
What does a switch do that a router doesn t? ›
Router: In routers, data is transmitted in the form of packets. Network switch: In contrast, data is transmitted in network switches in the form of frames and packets. In the L2 switch, it is transmitted in frame form.
Is my home router also a switch? ›
While some routers are manufactured as a network switch and router combo, a router on its own performs a separate function from the switch even though sometimes they are found in a single device. For a modular setup, the switch, hub and router will all be separate devices on the local network.
Can a switch work without a router? ›
So while you can use a switch to create a LAN that networks local devices without a router, the devices all have to be connected by physical Ethernet cables. In addition, you wouldn't be able to effectively share an internet connection between all of the devices without connecting the switch to a router.
Are routers just switches? ›
Just as a switch connects multiple devices to create a network, a router connects multiple switches, and their respective networks, to form an even larger network. These networks may be in a single location or across multiple locations.
What is the main difference between a router and a switch? ›
Routers determine the optimal paths for data packets to travel between networks, acting as intelligent dispatchers that ensure efficient routing and prioritize traffic based on predefined rules. In contrast, switches facilitate communication between connected devices within a single network.
Routers and switches remain indispensable components to provide the foundation of connectivity, security, and network management within the Cloud.
Can you have two routers? ›
In short, yes! It is possible to use more than one router on the same home network, but you do need to be wary about the way you do this.
What is the use of a router? ›
It sends information from the internet to personal devices like computers, phones, and tablets. These internet-connected devices in your home make up your Local Area Network (LAN). Once a modem brings in information from the internet, a router distributes this data to your personal devices.
Does switch go before or after router? ›
Commonly, in a home setup, you will see the modem installed first, followed by a router and then the Ethernet switch. Here is the key operational principle: the modem passes the public IP address to the router, and in turn the said router assigns private IP addresses to the devices connected to it.
Do I need a switch for my home network? ›
If you want to use several devices over a wired internet connection, or if you plan to install Ethernet ports in the walls of your home, you will need a network switch.
Can two switches communicate without router? ›
Two switches can communicate with each and there is no need of router. Router is required only when you have different subnets to communicate with each other.
Does a network switch replace a router? ›
No. A network switch is different than a router. Both are essential for complex network operations, but they perform different functions. A network switch is used to connect devices together on a network and may enable administrators to manage network traffic and security more effectively.
