All Ethernet Switches
Ethernet switches are the central hub in any Ethernet network connecting network devices such as computers, controllers and Wi‑Fi points. Ethernet switches use a switching process to forward data packets only to the correct destination, ensuring efficient and reliable communication between all connected devices. Where a simple hub just bounces signals everywhere, an Ethernet switch actually looks at both the wires and the data frames, picks where each packet should go and makes the network run smoother with fewer traffic jams.
A managed switch provides more control than an unmanaged switch. Administrators using managed switches can watch traffic, set VLANs and add Quality of Service (QoS) rules so that important data jumps ahead. Unlike managed switches, unmanaged switches just plug in and push traffic straight between each device on their own, so they are perfect for tiny networks.

More Information about Ethernet Switches
Because you need both flexibility and power, PoE switches combine data with electricity so that you can power PoE devices such as IP cameras, wireless access points, and VoIP phones. This cuts out the extra power units and makes the install easier and reduces cabling costs. Most newer managed switches—even the basic Ethernet models—now have PoE built in, which lets them send data and feed power through the exact same cable at once. That feature is useful in factory automation, building control systems and even security setups that count on devices like sensors or controllers.
FAQs
How do Ethernet switches work?
Ethernet switches work by receiving data packets from connected devices and forwarding them only to the specific device or port they’re intended for, ensuring efficient and collision-free network communication.
Is a network switch the same as an Ethernet switch?
Yes, a network switch and an Ethernet switch are essentially the same device, as both transmit data within a local area network (Ethernet LAN) using Ethernet protocols to connect multiple devices efficiently.
Can an Ethernet switch manage devices connected to multiple networks?
A standard Ethernet switch cannot manage devices connected to multiple networks unless it is a managed Layer 3 switch, which can perform routing functions between different network segments.
Can Ethernet switches provide network connectivity to wired and wireless security cameras?
Yes, Ethernet switches—especially PoE switches—can provide network connectivity and power to wired security cameras, while also connecting to wireless access points that serve wireless cameras.
What is a physical transport layer?
The physical transport layer refers to the layer in the OSI model responsible for the actual transmission of raw data bits over physical media such as cables, fiber optics, or radio signals.
Basics of Switches, Routers & Hubs
Ethernet hubs, switches and routers connect computers to networks, devices and other computers.
Ethernet hubs are the least intelligent of the three devices. They simply take any message that is received and transmits it to every other device connected to that hub. For example, if CPU 1 on a network wants to send a message to CPU 5, it will send that message through the hub.The hub will then take that message and send it out to every connected device on that hub regardless of the intended target. When CPU 5 receives that message and wants to respond, it will send its response through the hub which sends it to every connected device. Ethernet hubs do not manage any data that is sent and tend to bog down networks. They also do not offer much security for the network. For these reasons, Ethernet hubs are are being replaced with network switches.
Switches transmit data from one device to another on the same network. Unlike a hub, switches use a switch table to learn where data came from and where to send it. Switch tables store Mac addresses and device ports. By storing this data, a switch can operate more efficiently than a hub, greatly reducing the traffic within the network.
Routers transfer data between devices while learning the location of those devices within the network. They are also a junction between two or more networks. An example of this would be a home router where the home network is connected to the Internet. Another example would be when the router connects two or more networks with different business functions. In addition to connecting two or more networks, a router offers important security features that help protect the network.
