Ancak *eşzamanlılık* ve *paralellik* arasındaki ayrıntılar oldukça farklıdır.


Farkı görmek için burgerlerle ilgili aşağıdaki hikayeyi hayal edin:

### Eşzamanlı Burgerler

<!-- Cinsiyetten bağımsız olan aşçı emojisi "🧑‍🍳" tarayıcılarda yeterince iyi görüntülenmiyor. Bu yüzden erken "👨‍🍳" ve kadın "👩‍🍳" aşçıları karışık bir şekilde kullanıcağım. -->

## Edit PR Titles

* Edit the PR title to start with an emoji from <a href="https://gitmoji.dev/" class="external-link" target="_blank">gitmoji</a>.
    * Use the emoji character, not the GitHub code. So, use `🐛` instead of `:bug:`. This is so that it shows up correctly outside of GitHub, for example in the release notes.
    * For translations use the `🌐` emoji ("globe with meridians").

Но внутреннее устройство **конкурентности** и **параллелизма** довольно разное.

Чтобы это понять, представьте такую картину:

### Конкурентные бургеры

<!-- The gender neutral cook emoji "🧑‍🍳" does not render well in browsers. In the meantime, I'm using a mix of male "👨‍🍳" and female "👩‍🍳" cooks. -->

 *  **OkHttp now rejects request headers that contain invalid characters.** This
    includes potential security problems (newline characters) as well as simple
    non-ASCII characters (including international characters and emoji).

 *  **Call canceling is more reliable.**  We had a bug where a socket being
     connected wasn't being closed when the application used `Call.cancel()`.
