Networks: Technical Synthesis

  • Identify the role and understand the operation of wired and wireless network interconnection components in a LAN and WAN environment
  • Master the operation of the layers and protocols of network protocol stacks
  • Acquire the state of the art of standards to be respected in a heterogeneous environment.

Administrators, technicians involved and / or responsible for implementing local networks LAN, WIFI, WAN.

Knowledge of the hardware and software environment.

3 Days.

This network training is punctuated by an alternation of presentations and practical work. For “Distance” training, they are carried out with a Teams or Zoom type videoconferencing tool depending on the case, allowing the trainer to adapt his pedagogy. our website full details on distance sessions or virtual classes.
