Understanding TCP/IP

Understanding TCP/IP


This course is ideal for network implementation personnel, network designers and managers, developers of distributed applications and those interested in learning more about networking.

The course also provides the prerequisite knowledge for our Controlling TCP/IP and Implementing TCP/IP on z/OS courses.


It is assumed that all delegates will have some basic knowledge of networking and LAN environments.


3 days. Hands on.

This course is available on site only. Please call for details.
