What is UI (User Interface)?

UI, or User Interface, refers to how users interact with a computer program or device. It's the bridge between a person and the technology they're using and how the user gives commands to the device and receives feedback.

Types of UI (User Interface)

There are several types of user interfaces, including:

• Command Line Interface (CLI) - This is also the most basic type of UI, where the user types in commands to the device, and the device returns output in the form of text.

• Graphical User Interface (GUI) - This type of UI also uses images and icons to represent actions and commands. It also allows users to interact with the device using a mouse, touchpad, or other input devices.

• Touchscreen Interface - Users interact with smartphones and tablets through this type of UI by touching the screen.

• Voice Interface - This UI type allows users to interact with the device using their voice. It's also becoming increasingly popular with the rise of virtual assistants like Siri and Alexa.
