Dual In-line Package ，也稱為 DIP封裝 ，簡稱為 DIP 或 DIL ，是一種 積體電路的封裝方式 ，積體電路的 外形為長方形 ，在其兩側則有 兩排平行的金屬接腳 ，稱為 排針 。DIP包裝的元件可以 焊接在印刷電路板 電鍍的貫穿孔中，或是 插入在DIP插座 （socket）上。 十四針的積體電路即稱為 DIP14 :  Vcc(電源) 第14腳  GND(接地) 第7腳 十六針的積體電路即稱為 DIP16 : Vcc(電源): Vcc(電源) 第16腳  GND(接地) 第8腳 方向和接腳編號 接腳以逆時針的順序編號 如右圖所示，當元件的識別缺口朝上時，左側最上方的接腳為接腳1，其他接腳則以逆時針的順序依序編號。有時接腳1也會以圓點作為標示。 例如DIP14的IC，識別缺口朝上時，左側的接腳由上往下依序為接腳1至7，而右側的接腳由下往上依序為接腳8至14。 資料擷取於Wiki: https://zh.wikipedia.org/wiki/%E9%9B%99%E5%88%97%E7%9B%B4%E6%8F%92%E5%B0%81%E8%A3%9D

  Definition - What does Graphical User Interface (GUI) mean? A graphical user interface (GUI) is an interface through which a user interacts with electronic devices such as computers, hand-held devices and other appliances. This interface uses icons, menus and other visual indicator (graphics) representations to display information and related user controls, unlike text-based interfaces, where data and commands are in text. GUIl representations are manipulated by a pointing device such as a mouse, trackball, stylus, or a finger on a touch screen. The need for GUI became apparent because the first human/computer text interface was through keyboard text creation by what is called a prompt (or DOS prompt). Commands were typed on a keyboard at the DOS prompt to initiate responses from a computer. The use of these commands and the need for exact spelling created a cumbersome and inefficient interface.
