Introducing TCPIP – Protocols and Implementation

Introducing TCPIP – Protocols and Implementation


The Introduction to Data Networking and TCP/IP course presents the basic theory of network’s hardware and software. The course starts from the OSI reference Model and data structure that explains the Ethernet protocol and LAN switching. We continue focusing on TCP/IP, from the basics on IPv4 and IPv6, through TCP and UDP, to application protocols that build the Internet.



Upon completion of this course, the student will be able to:

  • Understand the concept and the structure of data networks
  • Understand Ethernet Local Area Networks (LANs) and LAN switching
  • Wwide Area Networks (WAN) protocols and services
  • Describe the TCP/IP suite of protocols
  • Understand IPv4 operation and addressing
  • Understand IPv6 operation and addressing
  • Understand UDP and TCP
  • Understand routing and routing protocols
  • Understand the operation of DNS
  • Understand the concept of multicast is IP networks
  • Describe the concepts of network security and protocols
