The Data Link layer of the OSI model deals with MAC addresses and switches look at MAC addresses when they process an incoming frame on a port.Ī frame is a data type that is used to carry data on all networking devices. Hubs are considered Layer 1 (Physical) devices whereas switches are put into Layer 2 (Data Link). You connect devices to a hub using Ethernet cable and any signal sent from a device to the hub is simply repeated out on all other ports connected to the hub. It looks just like a switch, but works differently on the inside.
Switches vs HubsĪ hub is an obsolete device that you would never want to buy these days. Finally, we’ll talk about modems and other networking terms like access points and gateways. Next, we’ll talk about routers and why they are different than switches and hubs. First, I’ll talk about the difference between switches and hubs, as both of those devices are in the same category. This is done for convenience and to simplify the setup process.In this article, I’ll try to explain the concept behind each of these terms without getting too technical. It is this type of hybrid modem and router in one that you will usually be provided by your Internet Service Provider. PC, Laptop, Smartphone or wireless deviceĪs technology has improved the router and modem have often become incorporated into one singular device. So in summary, to connect to the internet the device connection order is outlined below: The router also does the job of providing a local IP address to each connected device, but they will all have the same external IP address, which is assigned by your Internet Service Provider, this is essentially your address on the internet so websites and emails know where to find you. If you connect your modem to a router (instead of directly to a computer) then all of the devices connected to the router can access the modem, and therefore, will be able to access the Internet. These connect through dedicated connection points on your wall. The modem typically provides either Fibre or DSL Internet service. Spark, Vodafone, MyRepublic, Slingshot etc). The modem is what is connecting to your Internet Service Provider (e.g. For the sake of this article, we will explain what a modem does as a standalone piece of computer networking equipment. In this case it does both jobs and many modems now also act as routers. This particular modem is a Netgear Wireless-N 300 Modem Router.

For this to happen the router will need to have a specific Ethernet port that is designed to connect to the router too the Ethernet port of a cable or DSL modem.Ī modem is a device that lets you access the Internet through an internet enabled device – smartphone, laptop, computer, smart TV etc. In order for computers or internet enabled devices on the LAN to connect to the Internet, the router needs to be connected to a modem. which is what people often think they do. Wireless routers like the one shown allow multiple computers and other devices, such as smartphones and tablets, to join the same network.Ĭonnecting to a router will provide access to a local area network (LAN) BUT it does not necessarily provide access to the Internet. These "wireless routers" often have one or two antennas on the sides which you can move to improve coverage although some other models house the antennas inside the router case.
This particular model is a Linksys WRT54GL Wireless G Router (a pretty solid wireless router if you are looking for one!)Įarly routers provided several Ethernet ports for wired connections but as technology has changed, most modern routers now offer wireless connectivity as well. An example of what a router looks like is shown below. This short FAQ will hopefully teach you the difference between a modem and a router and will let you understand the functions of the two different devices.Ī router is the small box that allows multiple computers to join the same network. The two devices look very similar and often their terminology is interchanged but they do each serve a different purpose.

and there is a lot of networking technology out there to shop for and upgrade your home or business. Modem vs Router read below A very common question as the term ‘ Router’ and ‘ Modem’ are two of the most common terms in the world of broadband… but whilst routers and modems are easily the most common everyday computer peripherals of the user at home, many people don't know the difference or the function of each one.
