Modems

A modem (or a portmanteau ) is a hardware gadget that helps convert data into a specific format suitable for a transmission medium. Hence, it works more as a network connector. As a result, the data is transmitted from one computer device to another.

Initially known as the Dataphone, the ideas came up in the 1960s. After some time, Dennis Hayes and Dale Heatherington released the 80-103A modem in 1977. It was the time when the idea became common in our households. In the early 2000s, the dial-up modem was used by computers to connect to the internet. Later the idea was replaced by broadband internet. Time passed until today when the young generation does not have a slight idea of what a dial-up modem is. Today a more advanced version of modems is used to transfer digital information from one end to another. In this discussion, we will explore the types of modems available in the market on this date.

Modems are electronic devices that are responsible for converting digital information into analogue signals and vis-à-vis. No matter what style or type, a modem is meant to assist the computer in transferring digital information. In the digital world of this date, a modem is a must-have for day to day professional and personal communication. This is the reason why more and more experts are spending time polishing the idea. As a result of ongoing efforts to advance the idea, different types of modems are available in the market. Below are some of the common types of modems that one uses in day to day life.

The Wi-Fi modem

Wi-Fi is the most common type of digital information conversion used these days. It is a single device that works both as a modem and a router. This device translates the internet data packets using a modem and sends them wirelessly to other devices around you using a router. Likewise, it can send the data back to the internet just like you send an email, video, photo or text. Today many internet service providers rent or sell any networking device on monthly subscriptions. Different types of Wi-Fi modems offer different speeds of internet, thus varying in functionalities.

A cable modem

It is a hardware device that helps computer devices communicate with the internet service provider over a landline connection. This device helps to convert analogue signals to digital signals to give access to broadband internet. A cable modem works by connecting Ethernet with a coaxial cable from the device to a computer or the network router. Here the network router helps to share your internet connection within different devices. Generally, a cable modem works with an (ISDN) Integrated Services Digital Network Device. This type of mode transfers bigger packets of data with high speed. This is the reason why they are mostly used for high-end applications like video streaming.

DSL and VDS modem

Both DSL and VDSL work the same way. The core purpose of these types of a modem is to bring internet access to your devices. However, there are some slight differences between the two types. The DSL device is connected to a conventional phone with the help of a copper wire. While on the other hand, a VDSL requires an optical fibre wire to do the processing. Speaking of speed, a DSL has a much slower speed as compared to the other. The VDSL is a comparatively advanced technology that also limits its availability and is also costly compared to a DSL connection.

A portable modem

This is just like a personalized internet box at your home. However, this box is not attached to a cable or telephone device. Rather these types of devices come with a SIM card inserted in them. If you have an unlocked portable Wi-Fi device, you can use any SIM card from any part of the world. This type of device is economical to use and can work with any data SIM from around the globe. A portable device helps to set up your personalized internet connection. Plus, you can connect up to 10 devices with it, including; laptops, tablets, mobile phones, iPods, cameras or game consoles.
