A modem is a device that converts an analogue signal from your internet service provider (ISP) into a digital signal that your devices can comprehend and vice versa. This enables your gadgets to communicate with one another through the internet.

The terms “modem” and “demodulation” are derived from the phrases “modulation” and “demodulation.” When the internet was initially formed, modems were used to modulate (or transform) the analogue signal used by telephone lines into a digital signal that computers and other devices could comprehend. The signal from your devices would then be demodulated by a modem and converted back into an analogue signal that could be delivered over a telephone line. Even though more modern technology is being employed, the word “modem” has stayed.

Most modems only have three ports: one for connecting to the internet, one for connecting to a router, and one for power. Older modems utilise telephone lines to connect to the internet, but modern ones use cable or fibre optic connections. In addition, modems will include at least one Ethernet connector for connecting to a router or computer.

When you sign up for an internet package via your ISP, you will normally be given a modem. However, your internet provider may often charge you a monthly subscription, and buying your modem will generally save you money after six months or so.

A router is a networking device that distributes (or routes) your internet connection from your modem to your network’s devices. This lets you use your computer, smartphone, smart TV, and other connected or wireless devices to connect to the internet and surf the web.

A router’s primary job is to redirect internet traffic to the appropriate device in your network. It does this by allocating an IP address to each of your devices so that when you attempt to access a page on your computer, it is not sent to your smartphone.

A router establishes your local network and allows you to configure it. You may use a router to configure security settings, prioritise traffic to certain devices, and more. A router also allows your devices to connect over the network. A router, for example, allows you to alter the settings of your smart home gadgets using a smartphone app.

There are several router varieties, but the two most prevalent are wired and wireless routers. Wired (or hard-lined) routers need a wired Ethernet connection to your PCs and other devices. WiFi routers employ built-in antennae to wirelessly broadcast your network’s internet signal.

Most routers include many Ethernet ports that you may use to connect to your devices via an Ethernet cable. If you want to send and receive data from the internet, they also have an Ethernet connection that must be linked to a modem.
