Benefits to you

• After presenting introductory information on protocols and standards, the course examines the components and services within TCP/IP and the central protocols of TCP/IP with emphasis on their role in successful node-to-node communication.
  
• The course includes lab exercises designed to reinforce the skills taught in the course. Services concepts and configuration are discussed and reinforced in the lab environment. Students also examine static and dynamic routing through a series of labs.
