Study 2018/12月份自我學習回顧

前言

其實可以看到，我從 11 月開始發文量變少（雖然本來就不多XD），主要是因為目前在複習一些理論課程，我又是手寫筆記派，所以自然地就比較少用 blog 記錄，反而是都寫成筆記，不但能強化當下的記憶，也方便日後複習。 ![12-study]({{ site.url }}/assets/images/12-study.jpg)

學習回顧

Network Principle

本月份主力衝刺在 Network 基本概念，這個月複習 Network Layer 和 Data Link Layer，雖然對於其中所使用到的 algorithm implementation 方式不熟悉，不過至少找回了概念，之後在 trace network protocol code 的時候也會更有方向。

學習日誌

本月份總共 9 天沒有唸書，因為剛好遇到跨年連假和公司年末要趕專案進度，所以減少了晚上自修的時間。
