Network Technology All-In-One
The aim of this course is to give the participants a far-reaching and at the same time deep insight into the structure and functioning of computer networks. In addition to live demos, the individual chapters are accompanied by practical exercises in which the participants work on tasks themselves and put the theory discussed directly into practice. Each person has dedicated, adequate network hardware available for this purpose.
Duration, location & language:
- 5 days
- Online, in-house or training center
