Chào mừng các bạn đến với hệ thống đào tạo trực tuyến của VnExperts!

Trong những năm qua, công nghệ thông tin, đặc biệt là Internet đã có những bước tiến vượt bậc, hỗ trợ đổi mới nội dung và phương pháp dạy và học. E-Learning đáp ứng được những tiêu chí giáo dục mới: học mọi nơi, học mọi lúc, học theo sở thích, và học suốt đời (lifelong learning). E-Learning tồn tại cùng và bổ sung cho học tập truyền thống. Nhìn chung, hệ thống e-Learning bao gồm:

Đầu tiên, E-Learning có hệ thống quản lý học tập (LMS - Learning Management System) giúp xây dựng các lớp học trực tuyến hiệu quả.
Một thành phần quan trọng nữa của hệ thống E-Learning là hệ thống quản lý nội dung học tập (LCMS - Learning Content Management System) cho phép tạo và quản lý nội dung học tập.
Điều quan trọng hơn là E-Learning đã được thế giới chuẩn hoá nên các bài giảng có thể trao đổi với nhau trên toàn thế giới cũng như giữa các trường học ở Việt Nam

Nhận thức được tầm quan trọng của E-Learning, VnExperts đã triển khai hệ thống đào tạo trực tuyến http://e-learning.vnexperts.net chuyên cung cấp các khóa học về mạng máy tính.

Rất hân hạnh được phục vụ quý vi!

Giới thiệu đôi nét về VNE (VnExperts)

- Với niềm say mê và mục đích đem kiến thức khoa học đến với những người ham học hỏi, tháng 8 năm 2003, VNE đã được sáng lập cùng sự ra đời của trang diễn đàn công nghệ thông tin http://www.vnexperts.net để mọi người có thể cùng nhau học tập và trao đổi những kiến thức bổ ích.

72 CompTIA Linux+

56 CompTIA Security+

07 CCSA (Check Point Security Administration NGX I)

07 CCSE (Check Point Security Administration NGX II)

07 CWASS (Certified Web Application Security Specialist Course )

- Với quy mô đào tạo khoảng 300 học viên/năm và không ngừng được đầu tư mở rộng hàng năm, VNE đang phấn đấu để trở thành học viện mạng hàng đầu tại Việt Nam vào năm 2007. Tham gia thị trường chứng khóan vào năm 2010.

- Không chỉ dừng lại ở các dịch vụ tư vấn và đào tạo, VNE còn triển khai các dịch vụ lắp đặt, bảo trì, thực hiện các giải pháp mạng LAN, WAN, VoIP, Video Conferencing, Security... Và đến nay chúng tôi đã hân hạnh phục vụ rất nhiều các đối tác điển hình: Công ty TOYOTA Việt Nam, Pjico, VDC Hải Phòng, Siemens, Ủy ban Nhân dân Tp.Hải Phòng, Học viên mạng Cisco Academy - Viện đại học mở Hà Nội, Công ty Ford Việt Nam, Công ty AQnet, Công ty Thông tin di động VMS, Cục Bưu điện Trung ương, Công ty tiết kiệm Bưu điện, Công ty Quang Minh DEC, Công ty cổ phần công nghệ phần mềm Việt Nam, Công ty Viễn thông Quốc tế VTI, Tổng Công ty Điện lực Việt Nam, Công ty Canon, Công ty cổ phần kỹ thuật toàn cầu GTC,...

- Cho đến nay VNE đã khẳng định được vị thế trong làng CNTT, được mọi người biết đến là một công ty hàng đầu chuyên về tư vấn và đào tạo, đặc biệt là trong lĩnh vực mạng.
