This course covers the most important fundamentals of modern networking technology and builds a solid foundation for entering the IT field. It explains network models, routers, switches, firewalls, and Wi-Fi, and covers IPv4 and IPv6 addressing, subnetting, and important network services such as DHCP and DNS. Tools such as ping, traceroute, nslookup, and Wireshark for the systematic analysis of network problems are also covered.

Presentation of the project results
Changes are possible, the course content is updated regularly.
You have a basic understanding of networking technology and are familiar with key network models, components, and services, as well as IPv4 and IPv6 addressing. You are also confident in using basic diagnostic tools and understand Wi-Fi, virtualization, and cloud networking.
This course is designed for IT beginners as well as for individuals who wish to acquire basic networking skills for roles in IT support, system administration, or for pursuing advanced IT certifications.
A solid foundation in network technology opens up a wide range of entry-level opportunities in IT support, help desk, and system administration. Network skills are in demand at nearly every company, as a stable and secure IT infrastructure forms the foundation for digital work processes. The knowledge you gain also serves as an important foundation for advancing into fields such as network administration, IT infrastructure, cloud computing, or IT security.
Your meaningful certificate provides a detailed insight into the qualifications you have acquired and improves your career prospects.
Didactic concept
Your lecturers are highly qualified both professionally and didactically and will teach you from the first to the last day (no self-study system).
You will learn in effective small groups. The courses usually consist of 6 to 25 participants. The general lessons are supplemented by numerous practical exercises in all course modules. The practice phase is an important part of the course, as it is during this time that you process what you have just learned and gain confidence and routine in its application. The final section of the course involves a project, a case study or a final exam.
Virtual classroom alfaview®
Lessons take place using modern alfaview® video technology - either from the comfort of your own home or at our premises at Bildungszentrum. The entire course can see each other face-to-face via alfaview®, communicate with each other in lip-sync voice quality and work on joint projects. Of course, you can also see and talk to your connected trainers live at any time and you will be taught by your lecturers in real time for the entire duration of the course. The lessons are not e-learning, but real live face-to-face lessons via video technology.
The courses at alfatraining are funded by Agentur für Arbeit and are certified in accordance with the AZAV approval regulation. When submitting a Bildungsgutscheinor Aktivierungs- und Vermittlungsgutschein, the entire course costs are usually covered by your funding body.
Funding is also possible via Europäischen Sozialfonds (ESF), Deutsche Rentenversicherung (DRV) or regional funding programs. As a regular soldier, you have the option of attending further training courses via Berufsförderungsdienst (BFD). Companies can also have their employees qualified via funding from Agentur für Arbeit (Qualifizierungschancengesetz).
