Dongle

Dongles are small hardware devices that are used to provide additional functionality or security to a computer system. In the context of Information Technology Input/Output And Storage Devices, dongles are typically used for data transfer, connectivity, or as a form of copy protection for software applications.

Dongles can be connected to a computer's USB port or other input/output ports, and they often contain specialized firmware or software that allows them to perform specific functions. For example, a dongle may be used to enable wireless connectivity, such as Bluetooth or Wi-Fi, or to provide additional storage capacity.

In terms of copy protection, dongles are often used by software developers to prevent unauthorized use or distribution of their applications. The dongle contains a unique identifier or license key that must be present in order for the software to run. This helps to ensure that only licensed users can access and use the software.

Overall, dongles are versatile devices that can enhance the functionality and security of computer systems, particularly in the context of Information Technology Equipment.
