Ever wondered what those little sticks you plug into your computer or TV are called? They’re dongles! Far from just
being a funny word, dongles are key players in making our tech work harder for us.
But what exactly is a dongle, and how did they become so essential?
What is a Dongle?
A dongle is a small gadget that connects to another device — typically through something like a USB or HDMI
slot — to unlock new functions or boost what it can already do.
Originally, back in the 1970s, dongles were all about keeping software safe from piracy.
Fast forward to today, and they’ve morphed into versatile tools that can do anything from pulling internet data to
turning your old TV into a smart hub for binge-watching.

In today’s world, dongles help fill the gaps between what our devices can do and what we need them to do. Need to
stream the latest viral series to your TV or connect to Wi-Fi on your old laptop? There’s a dongle for that.
They’re like little superheroes for our tech, giving devices new powers and extending their usefulness without
needing a tech upgrade.
How Dongles Work
Dongles may seem small, but they pack a big punch. They work by plugging into a computer or other device, instantly
boosting its capabilities or adding new features.
But how does this tiny tool manage to do so much?
At its core, a dongle acts as a bridge. It uses Device-to-Device (D2D) communication ,
allowing your gadgets to ‘talk’ to each other seamlessly.
Whether it’s sending video to a screen or transferring data from one device to another, dongles facilitate this
conversation without any hassle.
Common Interfaces:
Dongles can connect through various ports, depending on their function. The most common interfaces include:
USB: For internet dongles, software security keys, and more.
HDMI: Used by media streaming dongles to connect to TVs.
Audio Jack: For audio dongles that connect headphones to devices lacking a headphone port.
Imagine you want to watch a movie from your laptop on a big TV screen. A streaming dongle like Google Chromecast can
make this happen. Just plug the dongle into the TV’s HDMI port, connect it to your laptop wirelessly, and voilà
— your movie is on the big screen!
Types of Dongles and Their Uses
Dongles come in all shapes and sizes, each designed for a specific purpose. Whether you need internet on the go,
want to stream your favorite shows, or need to ensure your software is secure, there’s a dongle out there that fits
the bill.
Let's explore the different types and how they make our digital lives easier.
Internet Access Dongles:
These dongles are lifesavers for those without stable internet connections at home or on the go. Simply plug one
into your computer’s USB port, and it uses mobile networks to get you online, much like a smartphone does.
Software Licensing Dongles:
For software that’s pricey or sensitive, licensing dongles add an extra layer of security. These devices ensure that
only authorized users can access the software, helping to prevent piracy and unauthorized use.
Wireless Connectivity Dongles:
Need to add Wi-Fi or Bluetooth to a device that doesn’t have it? Wireless dongles are here to help. Plug one into
your device, and instantly connect to wireless networks or other Bluetooth-enabled devices without any fuss.

Devices like the Google Chromecast or Amazon Fire Stick
turn any HDMI-equipped TV into a smart TV. Simply connect the dongle to your TV and stream content directly from the
internet.
Vehicle Diagnostic Dongles:
OBD-II dongles are a cornerstone of modern vehicle telematics , offering car
enthusiasts and professionals real-time insights into engine performance, fuel efficiency, and GPS location
tracking. The AutoPi dongle stands out by
seamlessly streaming data to the cloud, facilitating remote access to comprehensive vehicle metrics.
Audio Dongles:
With many new devices dropping traditional headphone jacks, audio dongles allow you to connect your favorite
headphones to devices that only have USB-C or Lightning ports.
Display Dongles:
Want to mirror or extend your laptop screen onto a larger display? As mentioned, display dongles like the Google
Chromecast facilitate this, making presentations or movie watching a breeze.
