CompTIA Network+ 國際認可證書課程
課程簡稱：CompTIA Network+ Training Course

CompTIA (The Computing Technology Industry Association) 於 1982 年成立，其推行的 Network+ 認證是一套中立的 (Vendor Neutral) 國際認證，目的是要確認您擁有建立、管理、保護與優化網絡的能力。

CompTIA

為何要考取 CompTIA Network+ 認證？

• 因其中立的特性，通常成為 I.T. 專業人士首先考取的認證。
  
  
• 全球 50 萬人持有，反映其受歡迎程度。
  
  
• 根據美國勞工統計局 (Bureau of Labor Statistics) 的分析，網絡管理人員的需求將於 2012 至 2022 年間提升 12%。
  
  
• 領先而中立的認證，會被全球各地的國際級機構重視，並被設定為必要的入職條件。例如 Dell、HP、Ricoh、Sharp、Xerox 及 Apple Consultant Network 技術人員便必需持有 CompTIA Network+ 認證。
  
  
• 為進修 Cisco、Microsoft、Oracle、IBM 等等更高級的商業認證作準備。
  
  
• “Network+ provides a solid foundation for networking professionals to pursue vendor-specific certifications such as the Cisco CCNA” - By Cisco.
