Distributed computing is a way for computers to work together to do something big. It works by breaking a task into pieces and letting different computers work on different pieces at the same time. That way lots of computers can work together to do something that one computer alone would take much longer to do. For example, if you wanted to understand climate change better, you could split up the big problem of analyzing the data into several smaller problems, give each one to a different computer, and then have them all work together to get the answers faster.
