    We removed this cipher suite and `TLS_AES_128_CCM_SHA256` from the restricted, modern, and
    compatible sets of cipher suites. These two cipher suites aren't enabled by default in either
    Firefox or Chrome.

    See our [TLS Configuration History][tls_configuration_history] tracker for a log of all changes
    to OkHttp's default TLS options.

- 行程可以被你或作業系統終止（kill）。此時它就停止執行，無法再做任何事。
- 你電腦上執行的每個應用程式、每個視窗等，背後都有一些行程。而且在電腦開機時，通常會同時有許多行程在跑。
- 同一個程式可以同時有多個行程在執行。

如果你打開作業系統的「工作管理員」或「系統監控器」（或類似工具），就能看到許多正在執行的行程。

例如，你大概會看到同一個瀏覽器（Firefox、Chrome、Edge 等）會有多個行程在執行。它們通常每個分頁一個行程，外加其他一些額外行程。

現在我們知道「行程」與「程式」的差異了，繼續談部署。
