What Is An Ethernet Switch?

Have heard about Ethernet Switch? I bet you have and that the reason you are searching for the answer. Hereunder I have brought you every answer related to the switch, its use, the best ethernet switch, and much more. It will be great if you read the article by till the end to not miss anything that could be important for you to know. So now let’s begin and understand What is Ethernet Switch and Ethernet Definition.

What Is An Ethernet Switch?

Ethernet Switch is a device that is used to connect to computers using an Ethernet port with which they do devices can talk to each other.

Switches can connect all the wired devices like Laptops, Computers, Servers, and let’s not forget the printers. When you use multiple Ethernet switches then you will get faster connectivity and smooth access on all connected devices that too at one time.

The ethernet was first introduced in 1990 and has been developing since then and have become one of the most commonly used forms of network switches.

How Does Ethernet Switch Work?

The Ethernet Switch works by creating a network and then using multiple ports to communicate between the devices that are connected to the LAN.

These Switches use multiple ports, unlike the routers that use only LAN or WAN.

Hubs are also similar to Ethernets as they also connect the devices using LAN.

Here is in detail that how does the ethernet switch works and how ethernet bridge is made

  1. Frames

Frames are arrangements of data that go over Ethernet networks and move information between the systems. An Ethernet frame decides a location where the data has to travel and a source address is a location where the device is sending the frame. In a standard seven-layer Open Systems Interconnection (OSI) model of the computer network, frames are an important part of Layer 2they are also called the data link layer. Sometimes even called “Link-layer devices” or “Layer 2 switches.”

  1. Transparent Bridge

A transparent Bridge is a very common way of bridging of ethernet switch function. With the help of transparent bridging, a switch starts working on its own without any configuration in switches or any change in the device network.

  1. Address Learning

The main purpose of the Ethernet is that they control the frames and how they are transmitting between the switch ports. They also make decisions like how the traffic is going which is based on 48-bit MAC that are used in LAN. The Ethernet switches can also deduct that which devices are of which segments.

  1. Traffic Filtering

As soon as the switch builds the database address it becomes very easy and smooth to select that how will the filters forward the traffic. As the address is learned it checks the frames and a decision is made as per the destination of the frame. Switches also have a great feature that is they can isolate the traffic to only the segments that require the frame from senders. And it can stop the unrequired flow of traffic to the unwanted ports.

  1. Frame Flooding

When the switch does not find ant frames from a specific source for a specific period of time then the entries in forwarding switches may drop. If there are drops then the traffic resumes as soon as the switch forwards the frame to the ports.

  1. Multicast Traffic

The LANs do not only transfer frames to one address it has the capability to send the frames to many different addresses and can be received by many endpoints. Broadcast addresses are one of the types of multicast addresses as they also group the endpoints of LAN.

Ethernet Splitter Vs Switch

After understanding what is ethernet let us see the difference between Ethernet Switch Vs Splitter

Ethernet Switch

Ethernet is a tool that helps connect all the wired devices to each other. It simply connects using one port and connects to the router’s switch through ethernet and then you can connect the ethernet device to other ports.

Ethernet Splitter

Ethernet Splitter is to reduce the number of cables that may be required and they come in pairs. The splitters convert two wires into one but you need another splitter on the other side just to unsplit it. Yes it does reduce the number of cables you use but it also reduces the data transfer output speed from 100MBPS to 1000 MBPS


The functioning difference between both of them are

  • Ethernet Switch

You have to only connect the switch to the router wire and the ethernet cable and then you can connect other devices

  • Ethernet Splitter

The splitters connect two cables as they are of 100 base T standard. But you need 2 splitters at a time as one is required at the other end to unsplit them. The Ethernet splitter is best when you have a small setup for 2 devices


Here are some important benefits have a read at them

Ethernet Switch

  • Nearly 80% of energy is saved
  • It is very durable as it is made of the metal casing
  • You get 8 ports
  • It has plug and plays feature

Ethernet Splitter

  • A single cable can be divided into 2 outputs
  • The design is simple and easy to use

Is An Ethernet Switch The Same As A Modem?

A modem is used to connect to the Internet. A router acts as a gateway to the computer network and is placed between a modem and a switch or hub. A switch connects devices such as a desktop, laptop, and access point to the router.

Can I Connect Ethernet Switch Directly To Modem?

Switch – You can connect a switch to the modem’s Ethernet port to provide Internet access to more than one computer. The number of computers that can connect to the Internet depends on the number of ports that the switch has.

Can I Connect An Ethernet Switch To My Router?

Connect an ethernet cable to one of the ports at the back of the switch, then connect the other end to one of the ethernet ports at the back of the router.

Will Ethernet Switch Slow My Connection?

An Ethernet switch should not affect your network’s internet speeds, but it can in some circumstances. In a home network, your internet speeds can be only as fast as your slowest piece of equipment.

Is An Ethernet Switch Better Than A Splitter?

Ethernet switches provide more connections than splitters, while potentially reducing workload on individual computers. They’re easy to connect to: just plug your ethernet cord into the port. Many switches are energy-efficient since they can sense which ports are not being used and adjust power accordingly.

The ethernet switch needs a power input for it to work and thus the other t signal can be divided into multiple signals and you get a high speed. All this and everything about ethernet I have described in the adobe article. You must go through the article properly so that you understand the difference and then choose the one you require. Now you must have understood about it and would not be confused between the other ethernets and ethernet switch.
