Router vs Switch: Must Know Differences

Protecting a network is becoming overwhelming, and learning essential tools and devices would help secure the network. If you want to understand the networking concepts, you can join Networking Online Course and learn the core concepts such as Local Area Network / Wide Area Network, The OSI Model, Network equipment, and many more.

In this blog, we will discuss routing and switching, the advantages of routers, and the differences between switching and routing.

What is a Router

One of the prominent networking devices of computers is the Router. The Router serves two crucial functions:

  • Develop and support a local area network 
  • Control the data incoming and outgoing of the network and data moving inward the network.

It also aids you in managing various networks and routes network traffic between them. For example, your Router in your home network has two connections—one to the internet and the other to your private local area network. Additionally, many routers have built-in switches that let you connect several wired devices.

What is a Switch?

Computer networking devices that connect various devices on a single computer network are known as the network switch. It is primarily utilized to route information via the network. The process of the connecting network is also denoted as a bridging device.

How does Router work?

A router links various networks and keeps monitoring the network traffic between them. As we mentioned above, Routers are connected in two ways, one to the internet and another to the private local network. 

Furthermore, routers have a built-in switch that permits you to connect various wired devices. Moreover, multiple Routers will have wireless radios that help you connect Wi-Fi devices.

To learn more about networking, you can join CCNA Course Online which helps you understand IP addressing, WLAN and VLAN, Network security and management, and many more core concepts. 

How does Switch work?

A network switch is denoted as a bridging hub, Media Access Control or Switch. Switch devices utilize media access control addresses to deliver information to the correct terminus. Moreover, the data link layer OS uses packet switching to obtain, process, and forward data.

Moreover, with the aid of the switches, we can manage the data, and switches understand the respective addresses to transmit the message. Further, it can determine from which computer message is being sent and to which computer the message must be sent. So, to increase the speed of the switches, we can improve their efficiency by faster network speed.

Difference between Router and Switch

      Difference between Router and Switch      

The following are some key distinctions between the Switch and the Router. Moreover, you will also discuss the advantages of the Router and which layer the Router uses as a device in detail.




Routers operate at Layer 3 of the Open Systems Interconnection Model. Network switches operate at the Data Link Layer, layer two of the Open Systems Interconnection Model.
The router will provide network address translation, NetFlow, and Quality of service The switch does not provide these services
Pile up  Internet Protocol addresses in the routing table and manage the address on its own. Pile up  Media Access Control addresses in a lookup table and manage an address on its own. But,  Switch can understand the media Access Control address.
Networking device 2/4/8 ports. A switch is a multi-port bridge. 24/48 ports.
Fewer duplex Therefore, there is no collision in full duplex.
The wireless and wired connection speed limits are 1–10 Mbps and 100 Mbps, respectively. The switch can only operate at 10/100Mbps.
aids consumers in making the quickest routing choice Likely to choose a more challenging route
The router has network address translation capabilities. Switches are unable to conduct network address translation.
The router performs better than the switch in different network contexts (Metropolitan Area Network/wide area network). A switch is quicker than a router in a local area network context.
Every port in Router has a unique broadcast domain. The switch only uses one broadcast domain; Virtual Local Area Network is not used.
Internet Protocol Addresses are central to router operation. Switches use Media Access Control addresses because they only operate within a single network.
Both wired and wireless networks can be used with routers. Switches can only connect to wired networks.

If you want to have an in-depth understanding of CCNA, you can join CCNA Course in Chennai which aid in understanding  the crucial concepts of Routers/routing protocols, IP Routing, and network protocol ( EIGRP, OSPF, and RIP)

What are the functions of the Router and the Applications of the Router? 

Here are some crucial router applications:

  • A switch is quicker in a local area network.
  • It permits you to divide your connection( internet) to all your devices. 
  • It has the capability of connecting multiple media and devices.
  • Run a firewall.
  • The Router will decide where to send the information from one computer to another computer. 
  • Filtering, switching, and packet forwarding.
  • The Router also ensures that information reaches its target location.
  • Link up with a virtual private network

Applications of Switches

Some applications of switches are:

  • With the aid of Switch, we can maintain the Data flow over the network.
  • LANs between medium and large have several linked managed switches.
  • Switches are primarily used in home and office applications. 
  • Home and office mainly utilize a single switch to access different broadband services.
  • It is used to connect devices in a computer network physically.
  • A switch can send data to any device in either half-duplex or full-duplex mode.

Now, we shall discuss the advantages of the Router in detail

Advantages of Router

  • With the aid of a Router, we can share network connections with multiple devices to increase productivity.
  • The Router provides stable and flexible connections, which help in connecting network hosts.
  • If the central processing fails to transfer the data packets, the Router finds alternative options.
  • A router allows it to organize data packets, reducing the data load.

If you want to understand networking concepts, you can join CCNA Course in Coimbatore and learn the four main concepts of networking such as :

  • LAN(Local Area Network)
  • PAN(Personal Area Network)
  • MAN(Metropolitan Area Network)
  • WAN(Wide Area Network)

Advantages of Switch

  • It aids in reducing the broadcast domains.
  • Supports Virtual Local Area Network, which can be used to logically segment ports
  • Switches can map ports to Media Access Control addresses using the Content Addressable Memory table.

Disadvantages of Router

  • When many computers are using a network, connections may become sluggish. We call this scenario a connection delay.
  • A router permits various computers to share the network, which may end in low speed.

Disadvantages of Switch

  • Limiting broadcasts is not as effective as using a router.
  • Inter-Virtual Local Area Network routing is necessary for communication between Virtual Local Area Networks, yet several multilayer switches are already on the market.
  • Multicast packet handling involves a lot of settings and thoughtful design.
  • It contributes to fewer broadcast domains.

Now, you would understand the switching and routing, router layer, and what are the functions of the Router? So, to have a profound understanding of Switch for the internet and what routing and switching are. You can join the CCNA Course in Bangalore and learn four modules of Introduction to Networks, Routing and Switching Essentials, Scaling Networks, and Connecting Networks.
