What is a dongle and how does it work?
A dongle is a small hardware device that connects to a computer or other electronic device to provide additional functionality or enable specific features. It typically plugs into a USB port or other interface and contains a microcontroller or other electronic components that perform a specific task. Dongles can be used for a wide range of purposes, including software licensing, encryption, and device connectivity.
When a dongle is connected to a device, it communicates with the device’s operating system and software applications to provide the desired functionality. For example, a software licensing dongle might contain a unique identifier that is recognized by the software application, allowing it to run only when the dongle is present. Similarly, a connectivity dongle might provide a wireless connection to a device, allowing it to communicate with other devices or networks.
What are the different types of dongles available?
There are several types of dongles available, each designed to provide specific functionality. Some common types of dongles include software licensing dongles, encryption dongles, connectivity dongles, and device emulation dongles.
