-
To enable participants to effectively apply the OS cocepts to design the multiprocessing & multi-threading systems requiring sycnhronization.
-
To enable participants to design the systems requiring the communication across the processes or across the system, thereby sharing the system resources as required.
Target group:
Professionals/Students looking to design & develop the Linux based advance application under the mult-threaded & multi-processing environment.
Pre-requisite
Knowledge of C Programming with comfortability in Linux environment
Methology
Every theoretical topic is accompanied by corresponding hands-on/assignment to get the deep understanding of the topic.
