Network switches are hardware devices that transfer data packets between multiple network devices such as computers, routers, servers or other switches. In this category, you will find a wide variety of switches including modular, fixed-configuration, unmanaged and managed, stackable, smart and PoE switches. Brands available include but are not limited to Cisco, Netgear, Hewlett Packard Enterprise, TP-Link, D-Link, TRENDnet, Juniper Networks and Brocade Communications. With such a wide range of switches available, understanding the types of switches will help you find the right solution to keep up with your requirements. If you are not sure on the best switch, please feel free to contact your supplier of choice for professional assistance.
A network switch (also called switching hub, bridging hub, and, by the IEEE, MAC bridge) is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device.
A network switch connects devices within a network (often a local area network, or LAN*) and forwards data packets to and from those devices.
Types of Network Switches
Switches are the connectivity points of an Ethernet network. These are small devices that can receive data from multiple input ports and send it to the specific output port that takes data to its intended destination in the network. There are different types of switches in a network. These are: Unmanaged switches
The Differences Between Managed and Unmanaged Network Switches. On a basic level, an unmanaged switch allows you to immediately plug-and-play devices into your network, while a managed switch allows for greater control over it.
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.
While a network switch can connect multiple devices and networks to expand the LAN, a router will allow you to share a single IP address among multiple network devices. In simpler terms, the Ethernet switch creates networks and the router allows for connections between networks.
The other terminal is marked as L1 and is the output to the light fixture. When you're wiring decorative light switches such as chrome or stainless steel etc, you'll find that the switch will also have an L2 terminal which means it's a two way switch.
A virtual LAN (VLAN) is a logical overlay network that groups together a subset of devices that share a physical LAN, isolating the traffic for each group.
How many devices do you need to connect to your network? Make sure you select a switch with enough Gigabit (10/100/1000 Mbps) Ethernet ports for the devices you want to connect to your network. If you think you'll add more devices in the future, choose a switch that will give your network room to grow.
The layer 2 and Layer 3 differs mainly in the routing function. A Layer 2 switch works with MAC addresses only and does not care about IP address or any items of higher layers. Layer 3 switch, or multilayer switch, can do all the job of a layer 2 switch and additional static routing and dynamic routing as well.
The number of ports on a switch varies according to the device's function. A simple residential router may have five ports, but a switch for a big network may have up to 52 ports.
