Router vs Switch: Must Know Differences
What exactly is a Router?
Routers are computer networking devices that perform two primary functions: (1) they establish and maintain a local area network, and (2) they manage the data that enters and leaves the network, as well as the data that moves within the network. Routers are also known as network management devices.
It also aids in the management of multiple networks and the routing of network traffic amongst them.
In your home network, your router has two connections: one to the Internet and one to the private local network that you have established. Furthermore, many routers include built-in switches that allow you to connect multiple wired devices to a single network connection.
What exactly is a switch?
Unified network switches (also known as network routers) are computer networking devices that connect multiple devices to a single computer network. Furthermore, it can be used to route information that is sent over networks in the form of electronic data. Because the process of connecting network segments is also referred to as bridging, switches are commonly referred to as bridging devices in general.
How Does a Router Operate?
A router is a device that connects multiple networks and keeps track of the network traffic that flows between them. A single connection to the internet is provided, along with a second connection to your private local network.
Furthermore, many routers include built-in switches that allow you to connect multiple wired devices to a single network connection. Many routers are also equipped with wireless radios, which enable you to connect Wi-Fi devices to them.
What is the procedure for using Switch?
In addition to network switch, the terms bridging hub, switching, and MAC bridge are also used. Network switches use MAC addresses to direct data to the correct destination. (See Figure 1). When data is received, processed, and forwarded by the operating system at the data link layer, packet switching is used.
A switch provides assistance in handling the data and is aware of the specific addresses to which the message should be sent. It has the capability of determining which computer the message is intended for and sending the message directly to that computer. The efficiency of the switch can be improved by increasing the network speed available to the switch. Routers are used in a variety of applications.
The following are some of the most important Router applications:
It establishes a local area network (LAN).
It makes it possible for you to distribute your internet connection among all of your devices.
Connecting various media/devices to one another is a must.
Install a firewall on your computer.
Routers are responsible for determining where information is sent from one computer to another.
Packet forwarding, switching, and filtering are all terms that are used in networking.
In addition, the router ensures that information is delivered to its intended destination.
Connect to a virtual private network (VPN).
Switches have a variety of uses.
The following are some examples of switch applications:
A switch is a device that allows you to control the flow of data across a network.
LANs of medium to large size that contain a number of managed switches that are linked together.
SOHO (Small Office/Home Office) applications, in particular, make extensive use of switches. The majority of small and medium-sized businesses (SOHO) make use of a single switch to access the various broadband services.
It is used in a computer network to physically connect the devices that are connected to it.
A switch can transfer data to any of the other devices in either half-duplex or full-duplex mode, depending on the configuration.
Difference between Router and Switch
Here are some important differences between the Router and Switch:
|Routers operate at Layer 3 (Network) of the OSI model.||Network switches operate at layer two (Data Link Layer) of the OSI model.|
|Router will offer NAT, NetFlow and QoS Services||Switch will not offer such services.|
|Store IP address in the routing table and maintain an address on its own.||Store MAC address in a lookup table and maintain an address on its own. However, Switch can learn the MAC address.|
|Networking device 2/4/8 ports.||A switch is a multi-port bridge. 24/48 ports.|
|Less Duplex||In Full Duplex, So, no Collision occurs.|
|The speed limit is 1-10 Mbps for wireless and 100 Mbps for wired connection.||The speed limit for the switch is 10/100Mbps.|
|Helps users to take the faster routing decision||Likely to take a more complicated routing decision|
|The router can perform NAT||Switches can’t perform NAT|
|In various types of network environments (MAN/ WAN), the router works faster compares to Switch.||In a LAN environment, a switch is faster than Router.|
|In Router, every port has its own broadcast domain.||The switch has one broadcast domain except VLAN implemented.|
|Router operations revolve around IP Addresses.||Switches work with MAC addresses as it operates within the confines of a single network.|
|Routers can work within both wired and wireless network situations.||Switches are restricted to wired network connections.|
The advantages of using a router
Here are some of the advantages and disadvantages of using a router:
It facilitates the sharing of a network connection among multiple machines, thereby increasing productivity overall.
A router allows for the delivery of data packets in an organised manner, which helps to reduce the amount of data being transmitted.
A router is a device that provides a stable and reliable connection between network hosts.
When the main part of the router fails to transfer data packets, the alternative parts are called upon to assist.
Advantages of Making a Switch
The following are the advantages and disadvantages of using Switch.
It aids you in reducing the number of broadcast domains that you have.
Supports VLANs, which can be used to help with logical segmentation of port traffic.
Switches can make use of the CAM table to map a port to a specific MAC address.
Routers have a number of disadvantages.
Here are some of the Router’s disadvantages and drawbacks:
When multiple computers are connected to a network, the speed of the connections can become sluggish. A connection wait is the term used to describe this situation.
A router enables multiple computers to share the same network, which may result in a reduction in network performance.
Switching Has Its Drawbacks
The following are some disadvantages and drawbacks of using Switch:
When it comes to limiting broadcasts, a firewall is not as effective as a router.
It is necessary to route traffic between VLANs in order to communicate between them, but nowadays there are many multilayer switches available on the market.
It takes a significant amount of configuration and proper design to handle multicast packets effectively.
It contributes to the reduction of the number of broadcast domains.
