Difference Between Modem, Router, and Switch
This section will compare the functions of modems, routers, and switch to understand the primary role each of these devices plays in making your networking system better.
Also, knowing the distinction will help you figure out what you need to elevate your experience.
Modem Vs. Router
Both of these products are often confused with being the same device; however, their features vary extensively. A modem is a hardware device used to connect your computer to the internet via cable wires, optical fiber lines, and more. This device translates digital signals into analog signals in the form of zeros and ones that help your devices be linked to the ISP.
Data from the local internet service provider is transferred to your device via modem, which operates at the OSI model’s data-link layer 2.
On the other hand, Routers help expand the network range and even connect to Wi-Fi. The router acts as a central device for sharing files and data and connecting all the small or large devices in the network. The Wi-Fi router ensures there is minimal traffic congestion by creating various pathways for the information to flow. It can also join several networks following the same process.
Data packets are used in routers to share data and files to the local network via the quickest pathway. This device works on OSI layer 3.
Apart from this, modem and router can work together to give a speedy internet connection. The data is continuously exchanged with the help of cable wires installed in these devices, making sure your network is connected to the internet.
Various products are available in the market that are integrated with both modem and router in a single device. The combination of both devices is ideal for large offices and workspaces.
Router Vs. Switch
Next up are the router and switch, both of these save the hassle of high data trafficking, but they still have some key differences. Generally, various devices are working simultaneously in a network, which can cause an extensive load on the system. So, installing a switch in your networking system ensures smooth functioning.
The primary role of a switch is to communicate information with only the required device, which prevents losing any data in the process of transmission. The switch works on the OSI model’s data-link layer 3.
The router transmits data among different networks to merge them, but the switch helps you target a device/network that requires specific data.
To put it more simply, your local ISP brings the internet to your home, making connections with other networks using the router with a specific IP address. On the other hand, the switch has nothing to do with other networks; it only allows the incoming and outgoing data to be shared among devices, which occurs inside your network.
Modem Vs. Switch
As you already know, a modem connects the devices in a network to the internet, while the primary feature of a switch is to ensure the network is not overloaded with data.
Of course, both of these devices are very different, but they play an essential role in your networking system as a modem makes your work more efficient, and the switch gets you a secure line to do all the work.
