Linux LPI Level 1 (LPIC-1) 國際認可證書課程

Linux 是一套免費及多功能的作業系統，除了可提供檔案及打印伺服器 (File and Print Server) 之服務外，Linux 又可以用作架設網站伺服器 (Web Server)、郵件伺服器 (Mail Server)、虛擬機器及服務 (Virtual Machines / Services) 等，再加上其高度的穩定性，所以現時受到各方的歡迎。有些公司為了讓 Linux 安裝方便，將許多的軟體組合起來與 Linux kernel 包裝成 Linux distributions，這就是我們一般比較常聽到的 RedHat、Fedora、Debian 以及 Ubuntu 等各種不同的 Linux Distributions。不同 Distributions 的基本操作是大同小異的，而本中心會教授現時最流行之一的 Fedora。

LPI 全名是 Linux Professional Institute，是一個來自加拿大的非牟利 Linux 專業團體。由於 LPI 的考試費用較為合理，考試制度及內容亦較齊全，所以 LPI 的考試制度會比其他 Linux 考試制度更適合香港的實際環境，而我們亦預計會有越來越多人選擇考 LPI 的考試。

LPI 的 Level 1 (LPIC-1) 認證主要介紹 Linux 的基礎知識。除了適合初學 Linux 者外，因其涉及現時 Linux 所採用之新技術，所以也適合舊版本 Linux 系統的管理者去提昇關於 Linux 的技術知識。

本課程將教授 Linux 網絡的建立，操作及管理，由淺入深，為你打下穩固的 Linux 網絡根基。修畢本課程後，學員可考取 LPI Level 1 (LPIC-1) 國際認可證書。本課程籌備多時，精心編排。由上堂、溫習、實習、做試題、考試研習至最後考試，均為你度身訂造，作出有系統的編排。務求真正教識你，又令你考試及格。
