What is the Difference between Switches and Routers?: Right in front of us, we have an image of two boxes that look very similar. They both have lights on the front and network ports on the back. So… how do you tell the difference between these two boxes? Well though they look similar, these two devices perform different functions within a network. Both the router and the switch are network-connecting devices. The router, on the other hand, operates at the network layer and is responsible for determining the quickest path for a packet, whereas the switch connects various devices in a network. So basically we can say that switches create networks while routers connect networks. To understand the difference between a Router and a Switch, let us have a close look to understand these two devices.
What is the Difference between Switches and Routers?
Difference Chart between Switch and Router
| Switch | Router |
|---|---|
| It connects several networked devices in the network. | It connects many switches and their associated networks. |
| It operates on the OSI model’s data link layer. | It operates at the OSI model’s network layer. |
| It is used on a LAN. | It can be utilized in LAN or MAN networks. |
| A switch is incapable of doing NAT or Network Address Translation. | A router is capable of doing Network Address Translation. |
| When making complex routing considerations, the changeover takes longer. | A router can make routing decisions significantly more quickly than a switch. |
| It only provides port security. | It includes security procedures to keep the network safe from security threats. |
| It is classified as a semi-intelligent device. | It is referred to as an Intelligent network device. |
| It may transmit data in either half-duplex or full-duplex mode. | It transmits data in full-duplex mode. We may, however, alter it manually to work in half-duplex mode. |
| It transmits data from one device to another in the form of frames (for L2 switches) and packets (for L3 switches). | It uses data packets to convey information from one network to another. |
| Switches can only connect to wired networks. | Routers can communicate with both wired and wireless networks. |
| Switches come in a variety of port configurations, including 8, 16, 24, 48, and 64. | By default, a router has two ports, such as a Fast Ethernet Port. However, we can specifically add the serial ports. |
| For the source and destination MAC addresses, it consults the CAM (Content Addressable Memory) table. | It consults the routing database to determine the optimum route for the destination IP address. |
What is a Switch?
A switch is a type of computer networking equipment that connects multiple devices on a single computer network. Switches provide the sharing of resources by linking together all the devices, including computers, printers, servers, etc., in a small business network. Switches are commonly referred to as bridging devices because the process of connecting networks is also known as bridging.
How does a switch work?
Multiple data cables are connected to a switch to allow communication between networked devices. Switches use MAC addresses to forward their messages. To receive, process, and forward data at the data link layer, the operating system employs packet switching. Switches simply retransmit packets out of every port of the hub except the port on which the packet was received, unable to distinguish different recipients, and achieving overall lower network efficiency. Unlike routers, switches are restricted to wired network connections. Switch stores the MAC address in a lookup table and end the message directly to the right devices.
What is a Router?
Routers are more sophisticated devices than switches. A router joins many switches and their separate networks to make an even larger network, just as a switch connects multiple devices to form a network. So basically a router works as a dispatcher, directing traffic and choosing the most efficient route for information.
How does a Router work?
Routers are devices that connect computers and other devices to the Internet. A router connects network devices by passing data packets between them. This information can be transmitted between devices or from devices to the internet. The router accomplishes this by allocating a local IP address to each device on the network. This guarantees that data packets are sent to the correct location rather than being lost within the network. Furthermore, many routers include built-in switches that enable you to connect several wired devices.

Conclusion
According to the explanation above, we can say that both are crucial devices for establishing a network and have their unique relevance in the network. However, to set up a home network and connect devices, we require a switch, and to link two networks, we require a router.
FAQ
Do I need a router if I have a switch?
Switches have no routing capabilities and cannot function in place of a router. Your router most certainly includes a four-port switch built in, but that doesn’t mean your new eight-port dedicated switch can replace it—the router is still required to act as a bridge between your modem and switch.
What comes first switch or router?
In a typical home arrangement, the switch should be placed after the router. Since the modem will only communicate with the first computer that connects to it A router is required to share the connection. As a result, the “initial device” is frequently a router.
Why is a router better than a switch?
While a network switch can link multiple devices and networks to increase the LAN, a router allows multiple network devices to share a single IP address. The router will enable PCs and other network-connected devices to connect to the internet and other networks.
Can I put my router after a switch?
In summary, it is not possible to connect a modem to a router. Not practically, at any rate. Each port on the switch has its IP address. From the outside, it appears that you have placed a managed switch before the router, but this still adheres to the premise that the router comes before the network switch.
How many switches can connect to a router?
The number of network switches that can be connected to a router is theoretically unlimited. Daisy-chaining allows you to link as many switches as you like together; however, this is not suggested because it increases the chance of producing a loop if they are not connected correctly.
