News that 'the server crashed' sounds dramatic, but the underlying idea behind the word server is actually fairly simple.

When people say 'the server crashed,' what is a server?

An always-on computer (or program) whose job is answering requests
A server serves: it responds to requests from clients (your browser or app). 'Crashed' means it stopped responding — overloaded or failed — the familiar scene whenever traffic stampedes.

A server is simply an always-on computer or program whose job is to answer requests from other computers, called clients — when your browser asks for a webpage, a server somewhere processes that request and sends back the data, and 'the server crashed' just means it stopped responding, usually from being overloaded or hitting a software failure.

It's not a robotic version of a restaurant waiter, and it certainly isn't another name for a game console — both are playful but literal misreadings of the word 'serve' rather than descriptions of the actual computing concept.

Server crashes are especially common during sudden traffic spikes, which is why sites sometimes go down right when a popular event or sale drives an unusually large number of people to request the same page all at once.
