Mostrarei alguns exemplos concretos nos próximos capítulos.

Os próximos conceitos a serem considerados são todos sobre o programa que executa sua API real (por exemplo, Uvicorn).

## Programa e Processo

Falaremos muito sobre o "**processo**" em execução, então é útil ter clareza sobre o que ele significa e qual é a diferença com a palavra "**programa**".

### O que é um Programa

   * number of elements and every element of {@code iterator1} is equal to the corresponding element
   * of {@code iterator2}.

   * <p>Note that this will modify the supplied iterators, since they will have been advanced some
   * number of elements forward.

## Reporting a Vulnerability

If you think you found a vulnerability, and even if you are not sure about it, please report it right away by sending an email to: ******@****.***. Please try to be as explicit as possible, describing all the steps and example code to reproduce the security issue.

* **Uvicorn**:
    * Will have the best performance, as it doesn't have much extra code apart from the server itself.
    * You wouldn't write an application in Uvicorn directly. That would mean that your code would have to include more or less, at least, all the code provided by Starlette (or **FastAPI**). And if you did that, your final application would have the same overhead as having used a framework and minimizing your app code and bugs.
