Understanding TCP/IP

AUDIENCE: Network implementation personnel, network designers and managers, developers of distributed applications and those interested in learning more about networking. The course also provides the pre-requisite knowledge for our Implementing TCP/IP on z/OS course.
PREREQUISITES: It is assumed that all delegates will have some basic knowledge of networking and LAN environments.
DURATION: 3 days. Hands on.
OBJECTIVES: To understand what network protocols are, why internetworking is important and the basics of TCP/IP in Internets and Intranets. To understand the functions of the different layers of a network architecture, where TCP/IP fits within a network architecture and what functions it performs.
