什麼是 PS/2?

PS/2 端口是 6 針迷你 DIN 連接器,用於將某些鍵盤和鼠標連接到 PC 兼容計算機系統。它的名字來源於 1987 年推出的 Personal System/2 系列個人電腦。

PS/2 是如何工作的?

PS/2 設備以每秒 10,000 位的速率一次發送一位數據。該設備使用兩根線與計算機通信——一根用於發送數據,一根用於接收數據。

使用 PS/2 有什麼缺點嗎?

PS/2 的一個潛在缺點是它使用專有連接器而不是 USB 等更常見的標準。如果您丟失或損壞設備附帶的適配器或替換電纜,這可能會導致您很難找到適配器或替換電纜。此外,一些較新的計算機不包括 PS/2 端口,因此如果您想在這些計算機上使用較舊的設備,您可能需要使用適配器。

PS/2 可以使用哪些類型的設備?

PS/2 最常用於將鍵盤和鼠標連接到計算機,但它也可用於其他設備,例如軌跡球、條形碼掃描儀和指紋讀取器。一些工業設備還使用PS/2端口進行數據輸入和輸出。

我可以使用帶有 PS/2 端口的 USB 設備嗎?

是的,您可以使用帶有 PS/2 端口的 USB 設備,方法是使用特殊的適配器電纜,將 USB 信號轉換為 PS/2 設備使用的信號(反之亦然)。這些電纜可以從銷售計算機配件的在線零售商和實體零售商處輕鬆獲得。

所有鍵盤都有 PS/2 端口嗎?

不,並非所有鍵盤都有 PS/2 端口 — 許多較新的型號都通過 USB 連接。但是,如果您貨比三家或尋找較舊的型號,仍然可以找到帶有 PS/2 端口的鍵盤(無論如何,這對於某些用戶來說可能更受歡迎)。如果您的鍵盤帶有 PS/2 端口,則還可以通過適配器電纜將其與 USB 端口一起使用。

所有鼠標都有 PS/2 端口嗎?

不,像鍵盤一樣,許多新型鼠標通過 USB 連接而不是 PS/2。但是,如果您貨比三家或尋找較舊的型號,仍然可以找到帶有 PS/2 端口的鼠標(無論如何,這對於某些用戶來說可能更受歡迎)。如果您的鼠標具有 PS/2 端口,則還可以通過適配器電纜將其與 USB 端口一起使用。

我丟失了 PS/2 適配器/電纜/等 — 我在哪裡可以獲得替換品?

如前所述,由於 PS/22 使用專有連接器,因此如果您丟失或損壞設備附帶的適配器或替換電纜,則可能很難找到適配器或替換電纜。然而,有許多在線零售商專門銷售 PS/22 設備的此類產品(只需在您最喜歡的在線零售商或搜索引擎上快速搜索即可)。您也可以在銷售電腦配件和零件的實體店找到它們,儘管根據您所在的位置,這些商店可能很少而且間隔很遠。

我的計算機沒有內置 PS/22 端口 — 我還能使用舊鍵盤/鼠標/等嗎?

是的,如果您的計算機沒有內置 PS/22 端口,但您有使用這些端口的設備,您只需使用適配器電纜(將 PS/22 信號轉換為 USB 使用的信號)將它們連接到您的計算機設備——反之亦然)。這些電纜可以從銷售計算機配件的在線零售商和實體零售商處輕鬆獲得。

為什麼對於鍵盤和鼠標我更喜歡 PS/2 而不是 USB?

您可能更喜歡 PS/2 而不是 USB,因為它在某些情況下可以提供更好的性能。例如,PS/2 比 USB 允許同時按下更多按鍵(稱為“n 鍵無衝突”),這對於需要同時按下多個按鍵的遊戲玩家或觸摸打字員來說非常重要。此外,由於 PS/2 接口僅專用於鍵盤和鼠標輸入,因此它可以提供比 USB 更穩定、更可靠的連接,而 USB 必須與其他設備共享帶寬。

我的筆記本電腦可以使用 PS/2 鍵盤或鼠標嗎?

這取決於您的筆記本電腦的硬件 - 如果它有內置 PS/2 端口,那麼您應該能夠使用兼容的鍵盤或鼠標。然而,許多較新的筆記本電腦沒有 PS/2 端口(因為它們越來越不常見),因此如果您想連接較舊的設備,您可能需要使用從 USB 轉換為 PS/2 的適配器電纜。

6 針迷你 DIN 連接器和常規 DIN 連接器有什麼區別?

常規 DIN 連接器比迷你 DIN 連接器更大且具有更多引腳 - 過去通常用於連接鍵盤和其他設備,但已大部分被迷你 DIN(以及後來的 USB)等較小連接器所取代。用於 PS/2 設備的 6 針迷你 DIN 連接器的尺寸與較大的 DIN 連接器相似,但針數較少。

使用 PS/2 設備是否存在任何安全問題?

與使用 PS/2 設備相關的一個潛在安全問題是擊鍵記錄的可能性,即有人可能攔截並記錄您的擊鍵,以竊取密碼或信用卡號等敏感信息。雖然任何類型的鍵盤(包括通過 USB 連接的鍵盤)都可能發生此類攻擊,但使用 PS/2 可能會稍微容易一些,因為通信協議更簡單,因此更容易受到窺探。

我可以同時使用 PS/2 鍵盤和鼠標嗎?

是的,大多數具有內置 PS/22 端口的計算機都支持同時連接鍵盤和鼠標。您將需要兩根獨立的電纜/適配器——一根用於鍵盤,一根用於鼠標——但除此之外,該過程很簡單。連接兩個設備後,您應該能夠像使用任何其他鍵盤和鼠標組合一樣使用它們。
