無線主機連網際網路步驟

與DHCP 運作流程類似

1. 首先無線主機啟動後會搜尋周圍的無線APs（wireless access point）

2. 無線APs會回應SSID 等資訊。

3. 選擇一個AP手動輸入SSID 與密碼。

4. 請求連線（做身份驗證）。

5. AP的DHCP server 分配給無線主機一個IP 位址與其他網路設定。

6. 無線主機就可以用網路設定為主機做設定，之後就能透過AP 連到網際網路了。

與DHCP 運作流程相異處

需要做身份驗證，如果驗證失敗就無法連上網際網路。


無線主機連網際網路步驟觀念應用

用在整理上類似DHCP觀念應用，先找（Find）出同類的東西（List），在一個一個拿起來細看（Closer look），哪些是準備要用的放在桌上（Dicide），不是馬上要用的放到鉛筆盒，鉛筆盒同類的只保留兩隻，這樣就可以保持桌面及鉛筆盒的簡潔。到要用桌面的筆時，卻發現筆上鎖，要拿著鑰匙的本人才能開鎖用筆，好處是筆只有自己可以用，不會被別人拿去亂用，到自己要用時卻發現裡面沒水了。
