Difference between Modem and Router

The main difference between Modem and Router is their Connectivity, that is, the work of the modem is to connect at your Home Network cht Internet (ISP) Internet Service Provider, it is also called the Gateway of the Network

While the work of Router is all wired and wireless. A network of devices such as switches, laptops, desktop printers, etc. is to be interconnected, so that all those devices can communicate with each other and use the Internet.

Let us understand this more easily now, whenever you need an internet connection at home or office, you talk to the ISP for this. So the device used to create internet connectivity between ISP and your home is called Modem.

Now internet connectivity has come to your home modem, but still you will not be able to use internet on your laptop, desktop, mobile or any other Davis, because the modem does not create a LAN network by itself and neither WIFi broadcasts the signal, for this you need a Router.

The router’s job is to create a wired and wireless LAN network, and it connects to the Modem via a LAN cable, so that all the devices in the network can also communicate with each other at the same time and give them Internet access.

By the way,

both the modem and the router are completely different from each other, and the functionality of the two is also different, so both devices are used in computer networks.

However, now Combine devices have also come in which both Modem and Router are available, that is, you do not need to install two separate devices, the router and the modem, but in one device you get both of these features.

The modem converts the analog signal received from the phone line or cable into digital information, so that the computer and other devices can understand this information, this process is called modulation.

Similarly, It converts digital info into analog signals, a process known as Demodulation.

It decodes the Signal’s received from the ISP. A local network cannot be created by this.
