Industrial Ethernet

Hubs and Switches create networks while Routers connect networks together.

A Hub connects several devices together creating a network and allowing them to communicate with each other. It is simply a multi-port broadcast device. It takes whatever comes in any port and broadcasts it out all the other ports. Hubs can be slower because they can’t send and receive packets at the same time and is subject to collisions where multiple device are trying to send packets at the same time.

A Switch does everything a hub does but is more efficient and smarter. They can send and receive packets of data at the same time elimination collisions that can slow down the network. Switches only send the information packets through the port of the device intended to receive the information within the network.

Managed Switches have the added ability to configure, manage, and monitor your network. This allows you to allow accesses to devices, control the data flow, and monitor performance along with detecting problems.

Routers connect networks together and can route packets to other networks until that packet ultimately reaches its destination. All routers have a WAN Port that connects to a DSL or cable modem that links computers to the Internet, so users can share the connection. Routers have an integrated switch allows users to easily create a LAN. This allows all the PCs on the LAN to have access to the Internet and Windows file and printer sharing services.
