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.
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.
