Computer Networks
This course offers a step-by-step immersion into the world of computer networks: from basic concepts and clear examples to complex technologies used in real corporate infrastructures. The training is structured so that even a beginner can quickly get oriented, while an experienced specialist can systematize and deepen their knowledge.
In the first lesson, you will learn what a computer network is, why it is needed, and how it is structured. Using simple analogies—like a WhatsApp group chat—we will explore the principles of device connections, the concept of protocols, the advantages of networks (such as resource sharing, load balancing, reliability, and location independence), and data transmission modes (simplex, half-duplex, full-duplex).
The subsequent modules of the course expand your horizons step by step:
- Types of networks and topologies - from local to global, from bus to star;
- OSI and TCP/IP models - layers, functions, comparison;
- Network equipment and cabling systems;
- Ethernet, ARP, VLAN, protocols for all levels;
- IPv4/IPv6 addressing, routing, BGP, OSPF, EIGRP;
- Switching technologies and IEEE standards;
- Security - from firewalls and IDS/IPS to VPN and cryptography;
- Network monitoring, diagnostics, and optimization;
- Modern approaches - virtualization, SDN, CDN, redundancy.
The course combines theory with practical examples, so you not only memorize terms but also understand how they work in real conditions.
After completing the program, you will confidently navigate the field of network technologies, understand architecture and protocols, and be able to design, configure, and analyze the performance of computer networks.
