Icons play a crucial role in the user interface of a computer system. They are visual representations of programs, files, or functions that users can interact with by clicking or tapping on them. Here is why icons are labelled pictures on the screen that represent a program:

Visual Representation:
Icons are designed to visually represent a specific program, file, or function. For example, a trash can icon typically represents the action of deleting a file. This visual representation helps users quickly identify and access the programs or functions they need.

Easy to Use:
Icons make it easy for users to navigate through the computer system. Instead of having to remember the names of different programs or functions, users can simply look for the corresponding icons on the screen.

Organized Interface:
By using icons to represent programs, files, and functions, the interface of a computer system can be organized in a visually appealing way. Users can easily arrange and customize their desktop by moving icons around.

Enhanced User Experience:
Icons contribute to a better user experience by providing a more intuitive and visually engaging way to interact with the computer system. Users are more likely to enjoy using a system that has well-designed and easily recognizable icons.
In conclusion, icons are the labelled pictures on the screen that represent a program. They are essential components of the user interface and play a significant role in enhancing the usability and aesthetics of a computer system.
