Switches and routers

Twitter Advertisement Sometimes technology can seem, well, techie. There are so many terms, acronyms, and types of hardware 10 Acronyms and Their Meanings You Need to Know in 10 Acronyms and Their Meanings You Need to Know in Technology still continues to improve dramatically and is certainly no exception. But, with new technology comes new terminology, and with new terminology comes new acronyms.

Switches and routers

Some technicians have a tendency to use the terms routerhub and switch interchangeably. One minute they're talking about a switch and discussing router settings the next. Throughout the conversation, however, they're still looking at only one box. Have you ever wondered what the difference is among these devices?

Router vs Switch vs Hub: The Devices Defined The functions of the three devices Switches and routers the router, switch and hub — are all quite different from one another, even if at times they are all integrated into a single device. Which device do you use, and when do you use it?

What is a Router?

Configuring IAS

The router forwards data packets along networks. Routers are located at gateways, the places where two or more networks connect.

Routers use headers and forwarding tables to determine the best path for forwarding the packets, and they use protocols to communicate with each other and configure the best route between any two hosts.

What is a Switch? In networks the switch is the device that filters and forwards packets between LAN segments. Switches operate at the data link layer layer 2 and sometimes the network layer layer 3 of the OSI Reference Model and therefore support any packet protocol.

Finally, what is a Hub? A hub is a common connection point for devices in a network. Hubs connect segments of a LAN. It contains multiple ports so when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets. So conversations regarding these devices can be a bit misleading — especially to someone new to computer networking.

The functions of a router, hub and a switch are all quite different from one another, even if at times they are all integrated into a single device. Let's start with the hub and the switch since these two devices have similar roles on the network.
