Read on to get a clearer picture of what you need to optimize your home network. When do you need a switch? What exactly does a router do? Do you need a router if you have a single computer? Network technology can be quite an arcane area of study but armed with the right terms and a general overview of how devices function on your home network you can deploy your network with confidence.
Here is the simplest network configuration available: This user cannot access the internet with a Wi-Fi device thus no access for smart phones, tablets, or other wireless devices and they lose out on the benefits of having a router between their computer and the greater internet.
When should you use a router? Given the low cost of home routers and the benefits gained from installing one on your network you should always use a router which almost always includes a firewall feature. Home routers are actually a a combination of three networking components: In a commercial setting the three pieces of hardware are kept separate but consumer routers are almost always a combination of both the routing and switching components with a firewall added in for good measure.
At the most basic level a router links two networks together, the network within your home however big or small and the network outside your home in this case, the Internet.
The broadband modem provided to you by your ISP is only suited to linking a single computer to the internet and usually does not include any sort of routing or switch functionality.
A router performs the following functions: A router manages those multiple connections and ensures that the right packets of information go to the right places. Related to the IP sharing function, NAT modifies the headers in packets of information coming into and out of your network so that they get routed to the proper device.
Without DHCP you would have to manually configure and add all the hosts to your network. This means every time a new computer entered the network you would have to manually assign it an address on the network.
DHCP does that for you automatically so that when you plug your XBOX into your router, your friend gets on your wireless network, or you add a new computer, an address is assigned with no human interaction required.
Routers act as basic firewalls in a variety of ways including automatically rejecting incoming data that is not part of an ongoing exchange between a computer within your network and the outside world.
On the other hand, if a sudden burst of port probing comes in from an unknown address your router acts as a bouncer and rejects the requests, effectively cloaking your computers. In addition to the inside-to-outside network functionality outlined above, home routers also act as a network switch.
A network switch is a piece of hardware that facilitates communication between computers on an internal network.
Without the switching function the devices could talk through the router to the greater internet but not to each other—something as simple as copying an MP3 from your laptop to your desktop over the network would be impossible.
Although the four-port limit on the super majority of home routers was more than enough for most home users, the last 10 years have brought a significant increase in the number of networkable devices within the home. As a side note, historically people often relied on hubs because they were so much cheaper than pricey switches.
Because hubs have no management component there are frequent collisions between packets which leads to an overall decrease in performance. Hubs suffer from a number of technical shortcomings which you can read about here. Consumer grade networks switches have fallen in price so steeply over the last 10 years that very few hubs are even manufactured anymore Netgear, one of the largest manufacturers of consumer hubs, no longer even makes them.
Because of the shortcomings of network hubs and the low prices of quality consumer-grade network switches we cannot recommend using a hub.
Returning to the topic of switches: Unplug the devices from your router, plug all the devices into the switch, and then plug the switch into the router. Your router likely has a four-port switch built into it but that does not mean your new eight-port dedicated switch can replace your router—you still need the router to mediate between your modem and switch.
There are two primary designations we are interested in: Ethernet connection speeds are designated in 10BASE. In order to take full advantage of the maximum speeds all the devices in the transfer chain need to be at or above the speed rating you want.
In this situation upgrading the switch would boost your network performance considerably. Outside of transferring large files and streaming HD video content across your home network there is little need to go out and upgrade all your equipment to Gigabit.
Unlike the easy to translate number-as-network-speed designation we find with Ethernet the Wi-Fi designations actually refer to the draft versions of the IEEE Like Ethernet, Wi-Fi speeds are limited by the weakest link in the direct network.

Rather than start off with a glossary of networking terms—and in the process slam you with a technical terms with no easy point of reference—let’s dive right into looking at network diagrams. The IP Showcase returns to IBCShow for , September At the RAI Amsterdam, Room E/ The IP Showcase is dedicated to educating show attendees on the business and creative potential of IP media solutions.

Standards matter, but most companies I have worked with will go with the best solution that solves their business problems first, if the problems are pressing. Standards are important, but. The IES series Industrial Ethernet switches provide 10/TX (FX some models) Full Duplex Ethernet connectivity to Ethernet enabled devices in harsh environments.
