Course detail

Operating Sytems and Networks

FEKT-MOSSAcad. year: 2019/2020

First part of the subject deal witch the fundamental principles of the operating systems, process management, thread management, interprocess communication, process and thread synchronization, memory management, file systems, operating system structures and virtualization. Second part of the subject concerned with computer network. Students obtain information about network protocols and standard as Ethernet, IEEE 802.1Q VLAN, PoE, TCP/IP and IP routing. Special attention is given on new IPv6 protocol.
