This lecture note explains important systems concepts in general. Operating systems, project-based learning, system-level perspective, . The printout copy provided in the FDNY Headqu arters is printed in black and white. A: System calls allow user-level processes to request services of the operating system. System processes are to be given higher priority than user processes. Operating systems with different version numbers are only considered if they are technically clearly different to each other. Write programs using the following system calls of UNIX operating system: a) FCFS b) SJF c) Round Robin (pre-emptive) d) Priority Topics covered includes: Threads and Processes, Concurrency and Synchronization, Scheduling, Virtual Memory, I/O, Disks, File systems, Network file systems, Protection and Security, Virtual machines, Cutting edge topics.
