TCP/IP Complete

Seminarziel

The primary goal of the TCP/IP Complete course is to equip participants  with a thorough knowledge and understanding of the TCP/IP protocol  suite. Through comprehensive sessions and practical exercises, attendees  will gain expertise in areas such as addressing (IPv4 and IPv6),  subnetting, routing, transport layer protocols (TCP and UDP), common  TCP/IP applications, network security, and troubleshooting. The aim is  to empower participants with the necessary skills and knowledge to  effectively work with TCP/IP networks and confidently address related  challenges in various professional settings.
