My view of the events taking place on my computer is very different to how a computer scientist, a engineer or a physicist would view what is happening inside the box. Leslie Lamport explains how the definition of an event distinguishes between these areas of research.
Our digital lives rely on distributed computer systems, such as the internet, but understanding the order of events in such systems is not always straightforward.
