Network Operating Systems
FEKT-BPC-SOSAcad. year: 2020/2021
The theoretical part of the course deals with the principles of operating systems. The practicals apply the theoretical knowledge in an operating system with the Linux core. The project deals with the knowledge application in modification of an operating system.
Learning outcomes of the course unit
Student should be able to:
- describe operating system types,
- define kernel and system call,
- define process and thread,
- explain process scheduling,
- compare process synchronization methods,
- define process deadlock,
- describe memory management,
- explain virtual memory,
- describe file systems,
- explain network communication as part of operating system,
- describe principle of network services,
- analyse attacks on operating systems,
- describe firewall and proxy server,
- secure network operating system.
