A Proof of Concept (POC) is a prototype or sample implementation of a proposed solution or system that demonstrates its feasibility and potential value. It is used to test the concept's viability and to evaluate its potential for success. A POC helps to validate the idea and to determine whether it is worth pursuing further development or investment. The goal of a POC is to prove that a solution can work in a real-world scenario and to identify any challenges or issues that need to be addressed before moving forward with full-scale development.

A graphical user interface (GUI) is a type of user interface that allows users to interact with electronic devices, such as computers, mobile phones, and gaming consoles, using visual elements such as windows, icons, and buttons. It is designed to make it easier for users to interact with these devices, as opposed to using a command-line interface, which requires users to type commands. The use of a GUI can make it simpler for users to perform tasks, such as launching applications, opening files, and adjusting settings. A well-designed GUI can also make it easier for users to understand how to use an electronic device, as the visual elements and layout provide context and cues for the user.
