Difference Between Modem and Router; Advantages of Using a Router

Modem and router are used interchangeably nowadays, and for good reason. Both provide your computer with an internet connection, but there are differences to consider.

Difference Between Modem and Router; Advantages of Using a Router

Modems and Routers are available as a single unit these days, but if you don’t have one of those then you must be aware that these two aren’t the same thing.

The modem is a data transfer device that connects you to the internet via ethernet. A router transfers the internet signal to multiple devices at once and allows devices within a local network to interact.

People running a single PC at home often connect their system directly to the internet provider’s line via a modem’s ethernet cable, but that’s not secure — something we’ll discuss later on.

Difference Between a Modem and Router

The primary function of a modem is to send internet signals from your service provider to your computer, typically through a router. While not recommended, users can also connect the modem directly to the system to stay connected to the internet.

Nowadays, internet signals are transmitted via broadband or fiber lines. In the past, when telephone lines were widely used, modems encoded and decoded digital information to ensure a steady route.

The modem is connected to the internet service provider’s line via telephone wire, fiber, broadband, or satellite. It then relays the internet to your system or router through an Ethernet cable.

A router cannot directly connect to the internet. It requires a modem to act as a bridge.

At home, your router connects to both the internet and your private local area network. It shares the internet signal, relayed by the modem, to multiple devices using the same IP address wirelessly or through an Ethernet cable.

A router is the connection between your local network and the internet. It enables multiple devices to connect to the internet with different IP addresses and allows devices on a local network to communicate with each other. Regardless of how many devices are connected to the internet through your router, all search queries are sent as if from one device, sharing the same IP address. Nowadays, routers are available as a single unit that combines hardware and software for internet connection and signal transmission to multiple devices, creating a home network.

Advantages of Using a Router

Connecting to the internet with your modem is possible and people do that too. Although using a router may feel unnecessary, it provides enhanced security, wireless internet to multiple devices, and the ability to share files over the local network.

Security

If you only have one PC at home and your ethernet connection through the modem works well for your needs, you may think that you don’t need a router because it will only add clutter. However, that is not entirely true.

A modem is not secure because it only transfers digital information, or data, between you and your internet provider. It doesn’t provide any security, which exposes your system to attacks over the internet since your public IP is being used.

Connecting your computer directly to the modem leaves it vulnerable to attacks from other internet users. They can snoop in, try to initiate communication with your system, and look for vulnerabilities.

Think of it like leaving your house window open or leaving your car keys in the ignition with the door open. Connecting directly to the internet without a router is essentially doing the same thing to your home’s digital connection. While you can rely on the firewall of your Windows or any other operating system, it’s not as reliable as a hardware firewall provided by a router. Even antivirus programs aren’t effective against these types of vulnerabilities. So, when it comes to security, a router is essential. It adds an extra layer of protection to your internet connection through its robust firewall, which is superior to the firewall of any operating system.

The router puts your devices on a private network, assigning a different IP address than the public one — creating a barrier between the internet and your system.

Wireless Internet for Multiple Devices, Connected Over Local Network

Routers provide a secure digital environment and eliminate the need for multiple ethernet connections by wirelessly transmitting internet signals via Wi-Fi. Using a router is especially advantageous for laptop users as it allows them to move freely around their homes. Additionally, routers are essential for connecting smartphones and other devices. As smart home technology evolves, routers will become even more necessary for staying connected to the internet and personal local networks.

A router connects multiple devices on one local network, allowing users to share files such as images, audio, or video. While a modem and router combo is convenient, using separate devices offers the advantage of selecting the best options available.
