What is the primary function of a dongle?
A dongle is a small hardware device that connects to a computer or other device to provide additional functionality or enable a specific feature. Its primary function is to act as an intermediary between the device and the desired functionality, allowing users to access features that may not be built-in to the device.
For example, a Wi-Fi dongle can provide wireless connectivity to a device that does not have a built-in Wi-Fi adapter. Similarly, a Bluetooth dongle can enable Bluetooth connectivity on a device that does not have a built-in Bluetooth adapter. Dongles are often used to add functionality to devices that may not have the necessary hardware or to upgrade existing hardware to support new features.
What is the primary function of an adapter?
An adapter is a device that allows two incompatible devices or systems to work together by converting signals or data from one format to another. Its primary function is to enable communication between devices that may not be able to communicate directly due to differences in their interfaces, protocols, or data formats.
For example, a USB-to-Ethernet adapter can connect a device with a USB port to a network using an Ethernet cable. Similarly, a DVI-to-HDMI adapter can connect a device with a DVI port to a display with an HDMI port. Adapters are often used to enable compatibility between devices that may not have been designed to work together.
What is the key difference between a dongle and an adapter?
The key difference between a dongle and an adapter is their purpose and functionality. A dongle is designed to add new functionality to a device, whereas an adapter is designed to enable compatibility between devices.
