This article outlined byMiniToolgives a complete review of Ethernet.
It elaborates on its definition, function, work policy, types, and examples.
Besides, this post also compares Ethernet with splitter, hub, and router.

What Is an Ethernet Switch?
Multiple Ethernet switch ports enable faster connectivity and smoother access across multiple devices.
How Does an Ethernet Switch Work?

The following are the terms and their functions of Ethernet switches.
They include source addresses where the traveling data come from and destination addresses where the data is traveling to.
When it connects to that destination, the switch will learn the correct port again.

Then, frame flooding stops.
It is also able to isolate traffic to only those segments needed to receive frames from senders.
Among those multicast addresses, broadcast addresses are a special form.

They group all endpoint destinations in the LAN.
Have you ever encounter Xfinity WiFi connected but no Internet access problem?
Are you looking for solutions to this issue?

They achieve those operations by adjusting speeds and combining users into subgroups to monitor web link traffic.
They can be plugged in and turned on.
Ethernet Splitter vs Switch
AnEthernet splitteris used to transform one Ethernet connection into several.
It is a small transit with 3 Ethernet ports, 2 on one side and 1 on the other.
The Ethernet splitter does not increase the number of devices connected via Ethernet.
So, 2 Ethernet splitters are necessary each time.
So, compared with an Ethernet switch or hub, an Ethernet splitter is not recommended.
If you want to know about hub vs switch, then you should read this post carefully.
you could know the types, features, and so on about hub vs switch.
In 2011, connecting internet segments by hubs or repeaters is deprecated by IEEE 802.3.
Routers are usually placed at the gateway between networks and route data packets along the connection.
