Hi Mi Fans,

Today I am back with another informative tech thread. If you’ve been on the Internet for a while, you’ve no doubt heard the terms “Modem” and “Router” , some of you might have taken the time to understand what they are, but still there are some other fans who are still confused by these terms don't worry guys this thread is for you guys. So this thread is all about the difference between "Modem", "Router" and "Repeater".

WHAT IS A MODEM?


A modem is a tiny box or device that sits between your computer and your wall or cable box, depending on the type of internet connection you have. If you’re using dial-up or DSL then your modem will connect to the wall and if you’re using a cable then it’ll hook up to your cable box or available coaxial cable. What your modem does is translate the data that is sent to it so that it can display on your computer. Computer information is stored digitally, however, information sent over phone and cable lines are analogue waves. So your modem takes the analogue waves, changes it to digital and delivers it to your computer.



DIFFERENT KINDS OF MODEMS:

1. CABLE MODEMS


Cable modems use coaxial cables. One end connects to the back of the modem and the other end connects to your wall or to the back of your cable box. Cable internet is considered to be “high speed” internet.

2. DSL MODEMS


DSL can either connect to an external modem (like cable, but a different plug-in), or your computer will already have an internal modem that will dial-in through your phone line. Unlike dial-up, you can still access the internet while talking on the phone.

3. DIAL-UP


Dial-up is the oldest form of internet connection. It uses your phone line to connect to your ISP. Dial-up modems are much slower compared to cable and DSL. Also, if you only have one phone line you won’t be able to access the internet at the same you’re talking on the phone.

WHAT IS A ROUTER?


A router is a small device that sits between your modem and computer. Most routers are about the same size and shape as a modem. The purpose of the router is to take the information from the modem and deliver it to your computer.


What is cool about a router is that it’s able to take this information from several networks and deliver them to several computers. In other words, you can be on your desktop in the office and your kids can be on their computer in their room, and you can both use the internet at the same time using the same internet connection.


In technical terms, a router is a Layer 3 network gateway device, meaning that it connects two or more networks and that the router operates at the network layer of the OSI model. Routers contain a processor (CPU), several kinds of digital memory, and input-output (I/O) interfaces. They function as special-purpose computers, one that does not require a keyboard or display.

HOW DO MODEM AND ROUTER DIFFER EACH OTHER?


The two major components in a small computer network are a modem (cable or DSL) and a wireless router. The router is wired to the modem, and the modem is wired to the cable company's coaxial cable or the telephone company's DSL phone line. For Internet access via satellite, the router is wired to a satellite modem.

MODEM :
The modem establishes and maintains the connection with the Internet provider's service and converts the signals from and to the router appropriately.

ROUTER :
a router is that it’s able to take this information from several networks and deliver them to several computers.


Having a separate modem and router lets you update each device more frequently so you can always have the newest routers with the latest technology, giving you the fastest network available.


WHAT IS A REPEATER?


Repeaters regenerate incoming electrical, wireless or optical signals. With physical media like Ethernet or Wi-Fi, data transmissions can only span a limited distance before the quality of the signal degrades. Repeaters attempt to preserve signal integrity and extend the distance over which data can safely travel.


Repeaters remove the unwanted noise in an incoming signal. Unlike an analogue signal, the original digital signal, even if weak or distorted, can be clearly perceived and restored. With analogue transmission, signals are restrengthened with amplifiers which unfortunately also amplify noise as well as information.


That's it Mi fans this all about Modems, Routers & Repeaters hopes your confusions has been cleared. So do you think all these 3 gadgets should be at our home for a better connectivity? Let me know your thoughts in the comment section below.
