什麼是互聯網?

互聯網是一個龐大的全球網絡,連接世界各地數百萬台計算機、人員和其他設備。它使我們能夠從世界任何地方訪問信息、即時發送消息並在線互動。

互聯網如何運作?

互聯網的工作原理是通過一系列路由器和交換機將網絡連接在一起。路由器在不同網絡之間轉發數據包,而交換機則鏈接單個網絡內的設備。這使得計算機能夠相互通信並訪問遠程服務器上存儲的內容。

什麼是網站?

網站本質上是存儲在網絡服務器上的數字文檔或文件,可以通過在網絡瀏覽器中輸入地址 (URL) 來通過互聯網進行訪問。一般包括文字、圖像、視頻和交互元素;這使得它們非常適合共享信息和為用戶提供服務,而無需安裝任何其他軟件。

什麼是網絡瀏覽器?

網絡瀏覽器本質上是一個應用程序,它為用戶提供查看存儲在網絡服務器上的文檔的界面;我們在瀏覽網站、下載文件以及一般使用互聯網時都會使用它。流行的例子包括 Google Chrome、Mozilla Firefox、Safari 和 Edge。

為什麼我們需要搜索引擎?

搜索引擎充當在互聯網上查找信息的導航工具;它們通過搜索數十億個頁面並在幾秒鐘內向我們呈現相關結果,幫助我們快速找到與我們的搜索查詢相關的文章和網站!如果沒有搜索引擎,我們就很難(如果不是不可能)在網上找到我們想要的東西。

Internet 服務提供商和 Web 主機有什麼區別?

互聯網服務提供商 (ISP) 是提供互聯網訪問服務的公司,通常收取一定費用。另一方面,虛擬主機是提供存儲空間以及網站開發和維護等服務的公司;他們還負責確保網站可以在線訪問。

什麼是域名解析?

域名解析 (DNS) 是將域名(例如 google.com)映射到其相應 IP 地址(例如,172.217.24.238)的過程。DNS 的工作原理是將請求引用到特定的名稱服務器,然後將其解析回域名,以便計算機可以訪問在線存儲的內容。

什麼是cookie?

Cookie 是您每次訪問網站或使用應用程序時存儲在您計算機上的小數據片段;這允許網站記住您的偏好或跟踪您在一段時間內多次訪問的操作。它們不一定是惡意的,但如果誤用或濫用,可以用來收集個人信息,這使得它們引起爭議。

如何保護我的計算機免受網絡安全威脅?

為了保護您的計算機免受網絡安全威脅,首先要安裝並定期更新防病毒軟件;這可以防止惡意軟件、病毒和其他惡意攻擊。此外,您應該注意您點擊和下載的內容,創建強密碼並儘可能避免使用公共 Wi-Fi。

我應該注意使用互聯網的哪些負面影響?

互聯網可能很棒,但也存在一些潛在的負面影響,例如網絡欺凌或騷擾、惡意攻擊/仇恨言論、身份盜竊和欺詐、數據隱私問題等。當然,採取必要的措施來保持安全並保護自己非常重要(如上所述)但最終歸結為在使用互聯網時保持警惕並做出良好的判斷。

什麼是網絡層安全?

網絡層安全是一種網絡安全,可保護網絡免受來自網絡內部或外部的惡意攻擊。它通過實施加密、身份驗證和訪問控制等各種技術來保護數據和維護隱私。

為什麼應該使用虛擬專用網絡 (VPN)?

使用 VPN 的好處包括增強在線隱私和匿名性、提高針對黑客和惡意軟件等網絡威脅的安全性,以及訪問因區域限製而可能無法訪問的內容(例如流媒體服務)。它還隱藏您的 IP 地址,使第三方難以跟踪您的在線活動。

我如何保護自己免受網絡欺詐?

您可以採取幾個步驟來保護自己免受網絡欺詐。其中包括僅使用具有安全連接的網站 (https://);保持警惕並關注網站網址;除非絕對必要,否則絕不披露信用卡信息;避免點擊通過電子郵件/消息發送的可疑鏈接或附件。此外,明智的做法是及時了解黑客和詐騙者使用的最新詐騙和網絡釣魚技術——畢竟,知識就是力量。

什麼是網絡釣魚以及如何發現它?

網絡釣魚是一種網絡攻擊形式,攻擊者試圖通過偽裝成合法來源來獲取用戶名、密碼或財務數據等敏感信息。網絡釣魚的跡象包括用英語寫得不好且存在拼寫錯誤的電子郵件、請求個人數據/財務信息、奇怪的 URL 鏈接等。意識到這一點,您可以快速發現潛在的詐騙並避免成為受害者。

什麼是惡意軟件防護措施?

惡意軟件防護措施包括採取措施防範惡意軟件感染或在任何現有惡意軟件造成重大破壞之前對其進行檢測。示例包括定期運行反惡意軟件軟件;確保您的操作系統已安裝最新補丁;連接可移動媒體(例如 USB 驅動器)之前對其進行掃描;並維護所有帳戶的強密碼。

第一個互聯網協議是什麼?

第一個 Internet 協議稱為網絡控製程序 (NCP),由 Jon Postel 於 1969 年提出。它被設計為連接到阿帕網(當今互聯網的前身)的計算機的基本通信協議。NCP 允許計算機傳輸數據、與其他節點通信並最終用於與遠程網絡建立連接。

誰發明了萬維網?

萬維網 (WWW) 是由 Tim Berners-Lee 爵士於 1989 年在 CERN 工作時發明的。他提出了一些巧妙的概念和技術,例如 HTML、超文本和 URL,這些概念和技術結合在一起使我們能夠跨全球多個設備和位置訪問內容。直到今天,他最初的願景對我們在線互動的方式產生了持續的影響。

隨著時間的推移,互聯網發生了怎樣的變化?

隨著時間的推移,互聯網已經發生了巨大的變化,從早期作為大學和政府的研究工具到現在成為我們日常生活不可或缺的一部分。這包括更快的下載速度;加強安全措施;更複雜的應用程序;更好的連接選項,如 4G 或 5G;以及無數新的數字服務,從流媒體服務、在線購物到社交媒體平台等。
