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.
NOTE: This course is not delivered with the FoldOut methodology.
Who should attend?
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.
