In computing, a powerful computer or program that provides data, services, or resources to other computers over a network. In everyday life, it can also mean a person who serves food or drinks in a restaurant.
From 'serve' + the agent suffix '-er', meaning 'one who serves'. The computing sense grew from the idea that one machine 'serves' information to others.
A restaurant server and an internet server are doing the same basic job: taking requests and delivering what was asked for. When a website is 'down', it’s like the digital waiter has vanished from the restaurant.
