In the subject “Network Technology”, Computer Science Experts for System Integration learn the fundamentals of modern network technologies. A central component is the OSI layer model, which serves as the basis for understanding network protocols such as DHCP, DNS, IPv4, and IPv6, as well as the processes of encapsulation and decapsulation. Switching and routing procedures are also explained and studied in more detail using protocols such as OSPF, NAT, and PAT. Topics related to public networks such as ISDN, DSL, GSM, HSPA, LTE, etc. are also included in the curriculum.
