什麼是樞紐?

在網絡中,集線器是將多台計算機和設備連接在一起的設備。集線器也可以稱為中繼器或集中器,它們充當局域網 (LAN) 的中心。在集線器中,每個連接的設備都位於同一子網上,並接收發送到集線器的所有數據。然後,集線器將數據轉發到所有其他連接的設備,從而創建一個在用戶之間共享數據的高效系統。

中心網絡如何工作?

集線器網絡是一種連接多個設備或節點以共享資源、信息和服務的計算機網絡。集線器網絡由一個或多個集線器(中央連接點)和所有其他連接設備組成。網絡上的每個設備都直接連接到集線器,集線器充當數據傳輸的中心點。數據通過集線器從一個設備發送到另一台設備,並且可以在連接到集線器的任何兩個設備之間交換。在中心網絡中,所有設備彼此共享帶寬,這意味著所有資源隨時可供任何連接的設備使用。然而,這也意味著網絡的總體容量較小,因為每個節點必須競爭對相同資源的訪問。像這樣,確保您的網絡有足夠的容量以確保最佳性能非常重要。此外,這種類型的網絡架構通常更適合較小的網絡,因為較大的網絡很快就會變得擁擠並降低整體性能。

我什麼時候應該使用集線器網絡?

中心網絡通常最適合不需要處理大量數據的小型本地網絡。與其他類型的網絡相比,這種類型的網絡的設置和維護更簡單且更具成本效益,非常適合家庭辦公室或小型企業使用。此外,在多個用戶需要同時訪問共享資源(例如打印機或文件服務器)的情況下,集線器網絡可能會很有用。由於數據的統一廣播,集線器網絡也不太容易出現瓶頸,從而防止單個設備主宰可用帶寬。然而,這意味著所有連接的設備必須共享相同的總帶寬,因為它們都具有平等的訪問權限。

網絡集線器還在使用嗎?

網絡集線器是用於連接網絡內的計算機的設備,允許在它們之間共享數據和信息。儘管交換機設備由於能夠提供更高效的網絡連接而通常受到青睞,但在某些情況下仍然會使用它們。網絡集線器還需要比交換機更多的佈線,這使得它們在大多數情況下不太受歡迎。在需要將具有不同速度或功能的多個設備在同一網絡上連接在一起的情況下,網絡集線器可能會很有用。

網絡集線器會影響速度嗎?

網絡集線器可能會對網絡速度產生影響,因為它們無法區分設備之間的流量優先級。這意味著所有連接的設備共享相同的帶寬,當多個設備同時使用時,會降低整體網絡速度。此外,即使只有一台設備需要數據,也必須將數據發送到所有連接的設備,這進一步減慢了通信時間。雖然對於現代網絡來說並不理想,但遊戲或流媒體等某些應用程序仍然可以從使用網絡集線器而不是交換機中受益。

網絡集線器有 IP 地址嗎?

網絡集線器通常沒有 IP 地址,因為它們被設計為透明的並在同一網絡上的連接設備之間轉發信息。這意味著任何設備都可以通過集線器發送數據,而無需直接與集線器本身通信。此外,集線器通常不知道其連接的設備的 IP 地址,因此無需分配地址。

中心網絡會恢復嗎?

集線器網絡仍在某些應用程序中使用,主要用於較低帶寬的任務,例如打印或文件共享。它們有時也用於小型企業和家庭辦公室,這些企業和家庭辦公室的預算限制意味著更複雜的網絡基礎設施可能成本過高。此外,一些組織選擇使用中心網絡以及更先進的技術來提供額外的安全功能和性能提升。總體而言,雖然中心網絡已很大程度上被其他網絡拓撲所取代,但它對於某些用例仍然可行。在選擇特定類型的網絡架構之前,請務必考慮您的具體要求,以確保您獲得滿足您需求的最佳性能。
