物聯網 (IoT) 是什麼意思?

物聯網描述了由實體設備、車輛、電器和其他嵌入感測器、軟體和連接的物體組成的網絡,使它們能夠收集和交換數據。物聯網允許在各個領域實現智慧互聯繫統,包括家庭自動化、醫療保健等。

什麼是安全超文本傳輸協定 (HTTPS)?

HTTPS 是 HTTP 的擴展,增加了加密和安全功能。 HTTPS 確保網路瀏覽器和網站之間傳輸的資料經過加密,防止未經授權的存取或竄改。

JavaScript 物件表示法 (JSON) 是什麼意思?

JSON 是一種輕量級的資料交換格式,易於人類閱讀和編寫,也易於機器解析和生成。 JSON 廣泛用於在伺服器和 Web 應用程式之間傳輸結構化資料。

什麼是結構化查詢語言(SQL)?

SQL 是一種用於管理和操作關聯式資料庫的程式語言。 SQL 可讓您執行查詢資料、插入或更新記錄以及建立或修改資料庫結構等操作。

無線區域網路 (WLAN) 是什麼意思?

WLAN 是指允許裝置在有限區域(例如家庭、辦公室或校園)內進行連接和通訊的無線網路。 WLAN 通常使用 WiFi 技術來提供無線連線。

什麼是美國資訊交換標準代碼 (ASCII)?

ASCII 是一種字元編碼標準,表示電腦和通訊設備中的文字。 ASCII 為不同的字元(例如字母、數字和特殊符號)分配唯一的數字代碼,允許它們以電子方式儲存和交換。

簡單服務發現協定 (SSDP) 是什麼意思?

SSDP 是一種網路協議,用於發現和通告區域網路 (LAN) 上的網路服務和裝置。 SSDP通常用於支援通用即插即用(UPnP)框架的裝置中。

什麼是域名系統安全擴充 (DNSSEC)?

DNSSEC 是 DNS 協定的一組擴展,提供加密安全措施來防止 DNS 欺騙和篡改。 DNSSEC 可確保 DNS 記錄的真實性和完整性,從而增強 DNS 整體安全性。

WiFi 保護存取 II (WPA2) 是什麼意思?

WPA2 是一種用於保護無線電腦網路安全的安全協定。與其前身 WiFi 保護存取 (WPA) 相比,WPA2 提供了更強大的加密和安全功能,使其成為廣泛採用的保護 WiFi 網路的標準。

什麼是獨立磁碟冗餘陣列 (RAID)?

RAID 是一種將多個實體磁碟機組合成單一邏輯單元的技術,以提高效能和/或容錯能力。 RAID 通常用於伺服器和儲存系統,以提供資料冗餘並提高資料傳輸速度。

虛擬私人網路 (VPN) 隧道是什麼意思?

VPN 隧道是指在 VPN 連線內封裝和加密網路流量的過程。當您建立 VPN 隧道時,您的資料將在您的裝置和 VPN 伺服器之間安全地傳輸,從而防止潛在的竊聽或攔截。

什麼是基本輸入/輸出系統 (BIOS) 刷新?

BIOS 刷新,也稱為韌體刷新,是更新或更換電腦主機板的韌體 (BIOS) 的過程。這樣做通常是為了向系統提供錯誤修復、安全性更新或附加功能。它涉及將更新的韌體安裝到主機板的韌體晶片上。
