Introduction
簡介
Imagine that a small marketing company has just hired you to set up their office network. Until now, all employees have been working remotely. Finally, the company has acquired office space for their five employees. All the equipment has already been purchased and delivered to the new office. Now it’s your job to connect everything together, so the employees can start working on site as soon as possible.
想像一家小型行銷公司剛聘用你，負責建置其辦公室網路。到目前為止，所有員工都是遠端工作。現在，公司終於為五位員工取得了辦公空間，所有設備也都已採購並送達新辦公室。接下來，你的工作就是把所有設備連接起來，讓員工能盡快開始在現場工作。
You realize the following:
你意識到以下幾點：
- It is important to correctly connect devices, so they can efficiently share resources such as printers, wireless access points (APs), environmental sensors, and the internet connection. This way, you cut down on unnecessary duplication and cost.正確連接裝置很重要，這樣才能有效共用印表機、無線基地台（AP）、環境感測器與網際網路連線等資源。這麼做能減少不必要的重複與成本。
- Connecting devices within a limited area allows for quicker data transfer, ensuring smooth communication and access to shared resources without any delays.在有限範圍內連接裝置，可加快資料傳輸速度，確保順暢的通訊與共用資源存取，不會有延遲。
- It is important to create a reliable and ready-to-scale infrastructure for any future needs.為未來的任何需求建立可靠且能隨時擴充的基礎架構，是很重要的一件事。
This figure shows all the equipment that the employees need for their everyday office work. It is now up to you to effectively connect it all together.
此圖顯示員工日常辦公工作所需的所有設備。現在該由你把它們全部有效地連接起來。
