## Máquina Servidora e Programa Servidor { #server-machine-and-server-program }

Existe um pequeno detalhe sobre estes nomes para se manter em mente. 💡

A palavra "**servidor**" é comumente usada para se referir tanto ao computador remoto/nuvem (a máquina física ou virtual) quanto ao programa que está sendo executado nessa máquina (por exemplo, Uvicorn).
