Course Modules
The course includes the following modules:
  • 1.  Introduction to Data Networks and Network Applications
    In this module we learn about the basics of data networks, the behavior of network applications, and their requirements from the data network.
  • 2.  The OSI Reference Model and Networks Data Structure
    In this module we learn about the OSI reference model and the structure of data that is transferred through the network.
  • 3.  Introduction to LANs & the Ethernet Protocol
    In this module we talk about Local Area Networks and the components that implement these networks, and we provide a brief description of the technology and how it started and developed over the years
  • 4.  LANs and the Ethernet Protocol
    In this module we learn about the Ethernet that implements modern LANs: the Ethernet frame structure, CSMA/CD and the collision mechanism, and cable types
  • 5.  Ethernet Types and Speeds
    In this module we talk about Ethernet types and speeds, from the old 10/100Mbps through 1/10Gbps and to the modern 40/100Gbps Ethernet for data centers and carrier networks
  • 6.  Introduction to LAN Switching
    In this module we introduce the principles of the LAN switching operation, along with speed and duplex operation of LAN switch ports
  • 7.   VLANs, VLAN Tagging & Prioritization
    In this module we learn about Virtual LANs and how they work, the VLAN tagging principle and implementation, and prioritization in local area networks
  • 8.  STP & RSTP
    In this module we learn about the Spanning Tree Protocols - STP, and Rapid STP, how they prevent loops in the network, their principles of operation, and the parameters they use in the process of network construction
  • 9.  WAN & the Public Network
    In this module we learn about the structure of the public network: the Service Provider network and the types of services it provides
  • 10.  WAN Traditional Services
    In this module we learn about the traditional WAN services: switching, transmission, and access technologies, along with ATM and SDH/SONet services
  • 11.  WAN Advanced Services
    In this module we learn about the new public network structure, the basics of MPLS-based WAN services, and the basics of Carrier-Ethernet based WAN services
  • 12.  Introduction to TCP/IP
    In this module we learn about the basics of the TCP/IP protocol stack with its protocols, and how it all fits together to provide end-to-end communications throughout the networks
