The purpose is to make the participants understand what the different protocols do and to have knowledge of other important functions such as routing and DNS. TCP/IP is a technology used in computers all over the world. This course will give you the fundamental TCP/IP knowledge in order to be able to attend other specific courses in areas such as routing-technology, VPN, realtime-IP, QoS and IT-security.
Target Audience
The target audience is technical personnel who work with company- and carrier-networks or others who need technical knowledge in TCP/IP.
Prerequisites
The students are expected to have knowledge on how computer works and knowledge in LAN and WAN technology before attending this course, equivalent to our course Data Communications Fundamentals.
NOTE: This course is not delivered with the FoldOut methodology.
