接下來要考慮的概念都與實際執行你的 API 的程式（例如 Uvicorn）有關。

## 程式與行程 { #program-and-process }

我們會常提到執行中的「行程（process）」，因此先釐清它的意思，以及與「程式（program）」的差異很有幫助。

### 什麼是程式 { #what-is-a-program }

「程式（program）」一詞常用來描述許多東西：

- 你寫的原始碼，也就是 Python 檔案。
- 可由作業系統執行的檔案，例如：`python`、`python.exe` 或 `uvicorn`。
- 在作業系統上執行中的特定程式，使用 CPU 並將資料存於記憶體。這也稱為「行程」。

### 什麼是行程 { #what-is-a-process }

「行程（process）」通常以更特定的方式使用，只指作業系統中正在執行的東西（如上面最後一點）：

- 在作業系統上「執行中」的特定程式。
