什麼是設備驅動程序?

設備驅動程序是一種軟件,可實現操作系統或應用程序與硬件或外圍設備之間的通信。它充當計算機不同組件之間的橋樑,使它們能夠相互交互。如果沒有設備驅動程序,計算機將無法運行任何類型的應用程序,因為所有程序都需要訪問底層硬件才能運行。設備驅動程序可以將數據從一個組件傳輸到另一個組件,從而簡化了用戶與其機器交互的過程。

存在哪些類型的設備驅動程序?

設備驅動程序大致分為兩類:通用和具體。通用設備驅動程序用於廣泛的目的,例如鍵盤控制和鼠標交互。它們通常作為操作系統的一部分包含在內,並且可以用於基本功能,而無需用戶的任何額外輸入。特定的設備驅動程序是為單個硬件(例如打印機、掃描儀、聲卡、視頻卡和圖形卡)製作的。這些通常需要手動安裝,但在購買新設備時可能會與某些設備或外圍設備一起打包。

設備驅動程序如何與硬件交互?

設備驅動程序提供有關軟件如何與特定硬件交互的信息。它們代表應用程序和用戶命令直接與處理器或 CPU 通信,在必要時發送指令並檢索數據以執行任務。這提供了兩個組件之間的雙向通信;數據從硬件發送回應用程序,以便它們可以適當地解釋它(例如,在屏幕上顯示內容)。類似地,從應用程序發送下來的數據可以由驅動程序轉換為處理器可以理解並代表處理器執行的指令,從而允許用戶使用軟件而不是直接發送到CPU 本身的低級命令來控制他們的機器。

基於網絡的技術如何使用設備驅動程序?

基於網絡的技術通常利用通用標準化的即插即用方法,通過 USB 端口或藍牙或 Wi-Fi Direct 等無線連接輕鬆連接多個平台上的設備。這最大限度地減少了與特定硬件直接通信相關的潛在兼容性問題,因為許多瀏覽器內置了對常用外圍設備(如網絡攝像頭、控制器、記憶棒等)的支持,完全消除了對傳統設備驅動程序協議的任何依賴。

如果計算機沒有安裝更新的驅動程序,可能會出現什麼問題?

如果計算機上安裝了過時或不正確的驅動程序,則可能會導致嚴重的性能問題,在某些情況下,從小故障到整個系統故障,儘管這種情況通常僅在特別必要的組件(例如GPU)變得過時/不受支持時才會發生。由於缺乏足夠定期進行的維護/更新而浪費時間 - 導致在嘗試某些操作(例如,嘗試視頻播放)時出現各種錯誤消息/代碼。此外,

如何安裝設備驅動程序?

要安裝任何設備驅動程序,您需要從硬件或外圍設備製造商的網站下載。然後按照他們的安裝說明進行操作。在某些情況下,驅動程序可能會預先安裝到某些計算機上或隨特定設備一起提供以方便安裝。但是,出於安全原因,確保僅使用原始製造商提供的驅動程序非常重要。嘗試安裝通用第三方版本通常會導致兼容性問題或安全漏洞(例如惡意軟件/病毒)。為了使您的系統組件保持最新,您應該定期檢查在線資源和/或利用大多數現代操作系統提供的自動更新工具。這將確保所有必需的軟件始終正確安裝。

當計算機沒有設備驅動程序時會發生什麼?

如果計算機沒有安裝必要的驅動程序代碼,則它將無法訪問其連接的任何硬件設備 - 這意味著任何應用程序都無法正常工作,因為它們需要這些資源才能準確運行。這意味著如果核心組件(例如 GPU)缺少最新驅動程序,您將無法啟動操作系統,甚至可能會遇到系統完全崩潰或藍屏的情況,從而導致性能嚴重下降,甚至在某些情況下,與上述部分相關的底層功能完全失敗,從而導致鎖定/凍結。

什麼是簽名設備驅動程序?

簽名的設備驅動程序是數字簽名的加密密鑰,它在軟件(例如,Windows)和相應的硬件/外圍設備(例如,打印機)之間提供身份驗證。這些“真實性證書”驗證代碼的合法性和功能性 - 在安裝其他第三方組件時提供額外的安全層。由於事先缺乏適當的驗證,這可能會損壞存儲在驅動器本身上的現有文件。未簽名的設備驅動程序可能仍然可以運行,但被認為風險要大得多。因為,惡意代碼很容易在分發之前被注入——與相關機構直接簽署的代碼相比,一旦它們在計算機上變得活躍,就會大大增加通過惡意軟件等進行感染/攻擊的機會。

我如何知道我的設備驅動程序是否已過期?

通常,當特定組件需要更新時,您會收到來自操作系統的通知。您必須相應地下載/安裝新驅動程序才能使任何更改正確生效。這也可以通過簡單地訪問製造商的網站並根據其中列出的所述組件類型的當前平台要求搜索最新的兼容版本來手動完成!如果做不到這一點,許多流行的反惡意軟件解決方案還提供有用的“驅動程序掃描”功能,幫助快速識別過時的項目- 使用戶不僅可以查明導致問題的潛在來源,還可以減輕因下載時等待時間超過必要時間而導致的相關速度下降/最終不必要地預先將其他不需要的元件安裝到機器上。

不同版本的 Windows 是否需要不同的設備驅動程序?

是的,您將需要不同版本的設備驅動程序,具體取決於您使用的 Windows 版本。這是因為不同版本的 Windows 可能需要不同類型的軟件和硬件設備之間的通信協議或接口。

我如何知道我的設備驅動程序是否正常工作?

您可以通過查看 Windows 中的設備管理器來檢查您的設備驅動程序是否正常工作。如果存在與特定驅動程序相關的任何錯誤或警告消息,則該驅動程序可能無法正常運行。
