In an era where computational demands surpass the capabilities of individual systems and where collaboration across borders becomes paramount, grid computing is the foundation for today's collaborative research. It enables users to access and analyze experiment data from all around the world without further knowledge of the complex systems in the background.

In this lecture, however, we will glance behind the user's single point of entry and delve into the foundational aspects of grid computing, from the historical background to the key concepts of a decentralized modern grid infrastructure. After the key concepts, we will examine the Worldwide LHC Computing Grid (WLCG) - the world's most sophisticated scientific computing grid - as a paradigm of contemporary grid infrastructure..
