    7. Objectives, learning outcomes and obtained knowledge The subject introduces students to the technologies applied in network embedded systems. Embedded systems operate in a network environment today typically, they integrated to complex systems. For integration network embedded systems should implement standard interfaces that must be implemented using the developers. Therefore, the subject introduces the modern communication interfaces, their properties, their hardware and software implementation, and resource requirements. As an example, the subject details USB, IEEE 802.x and TCP/IP in the lower layers of protocol hierarchy, and CORBA, DCOM, HTTP, XML, web services, SNMP, FTP on the higher layers.
