Difference Between Modem & Router
Difference Between Modem & Router


 I'm getting to explain the difference between the 2 now if you would like internet inside your home or business you've got to possess a modem a modem is what brings the Internet into your home or business a modem establishes and maintains a dedicated connection to your internet service provider to offer you access to the. Internet now the rationale why you've got to possess a modem is due to it two different types of signals that are used on a computer and on the web a computer only reads digital signals while signals out on the web are analog as analog data comes in from the web the modem d modulates the incoming analog signals into a digital signal in order that a computer can know it and a modem also modulates outgoing digital signals from a computer into an analog signal as it goes out on the web .

What Is Modem?


This is often where we get the word modem the word modem means modulator demodulator which is exactly what a modem does it modulates outgoing data from a computer and demodulates incoming data from the internet.  Now a router comes in after the modem now there are differing types of routers there are routers that are utilized in businesses and bigger organizations and there are smaller routers that are used in homes and little businesses. But they basically do an equivalent thing except for this video we're getting to use the tiny office/home office router that the majority of us are conversant in now a router is what routes or passes your internet connection to all or any of your devices in your home or business .



It directs it to all of your computers tablets phones and so on in order that those devices can access the internet a typical small office/home office router like this one here will have a built-in switch with multiple ports in order that you'll connect multiple devices using an coaxial cable connection and it also functions as a wireless access point in order that wireless devices like tablets and laptops can have internet access now technically you actually don't need a router. If you simply want one among your devices to access the web you'll  just plug that devices network cable directly into the modem then you'll be ready to access the web however like most homes and businesses you're going to have multiple devices that require access to the web and that is where you would need a router there also are differing types of modems two of the foremost common types are cable . DSL modems so depending upon what type of internet you are going to use you need to use the right sort of modem cable modems are connected to your home using a coax cable is usually provided by an equivalent company that provides you with cable television such as Comcast which is one among the most important providers within the us .DSL modems are connected employing a typical phone line DSL is provided by companies such as AT&T which is that the largest provider within the u.s. now tons of times your internet service provider once they send you a modem or if you were to shop for one at the shop the modem could be a modem router combination .

What is Router?


So it'll be a modem with a built-in wireless router in one physical device like this one here so here is an example of several different networks on how they connect to the web for instance this network here on the left is employing a cable modem and it's employing a small office/home office router in order that it's computers in the tablet can have internet access on a bottom we've another network and this network is employing a DSL modem. and it's also employing a small office/home office router in order that it's computers the laptop and the tablet can access the web the network here on the proper is an example of a business network and it's using a cable modem and it's employing a business router so we will connect its computers and its server and eventually we have the network here on top and this only has one device that needs internet access so it doesn't got to use a router it can just directly hook up with the modem because just one device needs internet access now if you're wondering how hubs and switches relate to routers and modems especially if you saw my other video where I explained the differences between hubs switches and routers well keep in mind that the majority routers will have a inbuilt switch inside them .



So there's no got to have a switch if you already have a router that features a switch  built into it so for instance a router like this might have a four port integrated switch in order that you'll connect four Ethernet cables for your wired devices therefore the only time .but you may need to feature a switch to the present network is if you needed more wired connections for your devices so you'll just connect a switch to your router then add more connections to the switch so just to clear things up even more over here we've the web with all of its routers. then because the internet is routed into this private network it first reaches the modem then it goes from the modem to its router with its integrated switch then it's passed to all or any of its computers .
