The internet - it's a luxury many of us have grown to rely on and simply can't live without. Yet, it's likewise a technology that most people don't fully appreciate or understand. After all, how many of us think about the modem when we're browsing the web or streaming our favorite TV show?
What Is a Modem?
A modem is a type of intermediary device that works as a gateway between your computer and the internet. It does this by translating data from your phone line, cable, or fiber optic cable into a form that your computer can understand, and vice versa. In the context of home networking, modems are often used in conjunction with routers to supply internet access. Modems can come in all shapes and sizes, and work in varying ways, but they all serve the same purpose: to get you connected.
How Do Modems Work?
A modem's inner workings can get really complicated depending on how far into detail you choose to go. Put simply, it acts as a connecting point between your home network to the wider Internet. How?
Your Internet Service Provider (ISP) does its job by sending the proper data line for making a connection to your home. This system largely works off of what's called analog communication and employs the use of continuous time varying signals when transmitting information. Where a modem comes in is that it can take this signal and change it into a digital form that your computer can understand. The process works vice versa when you're sending data from your home - the modem will take the digital form and translate it back into an analog signal for your ISP to read.
This all happens in a matter of milliseconds and without you even having to think about it - which is good, because it's a complicated process.
Is A Modem the Same as A Wi-Fi Router?
While both a modem and a WiFi router are necessary for getting your devices online, they serve very different purposes.
A modem is a device that connects your computer to the internet. It allows you to send and receive data over a network. Without it, you're not able to connect to the wider Internet, period.
A WiFi router, on the other hand, is a device that allows all of your wired and wireless devices to use that Internet connection at once and also allows them to talk to one another without having to do so over the Internet.
In short, you need a modem to get online and a WiFi router to create a home network.
Why Do I Need a Modem?
In order for you to get online and connect to the internet, you need a modem. If you want to be able to do that from home, then you need a home modem. These days, most people opt for some type of broadband connection like cable or DSL, and in order to connect to those you need a specialized modem that's compatible with the service.
What are The Different Types of Modems?
Cable
Cable modems are one of the most popular varieties of the technology, largely because of the fact that they’re relatively affordable and offer high speeds. They work by using the same cables that deliver your TV service into your home to send data back and forth. The main downside of cable modems is that they can be temperamental, especially during bad weather.
DSL
DSL modems are very similar to cable modems, except they use your home's existing telephone line to connect you to the internet. The upside of this is that it's generally a more reliable connection - bad weather won't affect it as much. The downside is that the speed can vary depending on how far away from the telephone exchange you are.
Fiber
Fiber optic modems are the newest type of modem on the market and offer speeds that are significantly faster than both cable and DSL. They work using thin fibers of glass to send data back and forth at lightning speeds. The downside is that they can be quite expensive and aren't yet widely available.
Wireless Internet Modem
A wireless cable modem is a type of modem that uses radio frequencies to connect you to the internet instead of wires. They're becoming increasingly popular as more and more people move away from traditional wired connections. The main downside of wireless cable modems is that they can be less dependable and offer lower speeds than their wired counterparts.
What Types of Features and Characteristics Can Modems Have?
Despite the fact that modems can come in multiple varieties, there are some popular features and characteristics they will all have in common.
OFDM
Orthogonal frequency-division multiplexing (OFDM) is a signal processing technique used by modems that allows them to split a single channel of data into multiple, smaller channels. This helps to reduce interference and improve reliability.
Data Encryption
Data encryption is a feature found in our modems that helps to protect your data from being intercepted by third parties. It works by encoding the data in such a way that it can only be decoded by the intended recipient.
Firewall
A firewall is a security feature that helps to protect your home network from outside attacks. It does this by blocking incoming connections that it considers to be unsafe. Many modems will have a built-in firewall, but you can also purchase standalone units.
