Think of your computer like a big city where different programs and files are like different buildings that you can go to. The path variable is like a set of directions that tells your computer where specific buildings (programs and files) are located within the city.
For example, let's say you want to open a program called "Microsoft Word". The path variable helps the computer find where the "Microsoft Word" building (program) is located in the city so it knows where to go to open it up.
The path variable is important because it allows you to quickly access your programs and files without having to navigate through all the different buildings in the city to find them. It's kind of like having a map that shows you the shortest and easiest route to get to your destination.
Overall, the path variable is a set of directions that helps your computer find and access programs and files. It's like a map for your computer to get from point A to point B with ease!
