Operating Systems KTU Notes 2019 Scheme OS S4 CSE

KTU OS Operating systems CST200 is one of the core subjects of CSE. Operating system analysis is essential to understand the overall function, performance, and functional transfer of a computer system, and to differentiate functions between hardware and software. This course introduces memory management, device management, process management, file management, and security and protection algorithms available on an operating system. 

This course helps you understand the basics of any operating system design so that you can diagnose and solve many problems in the operating system by expanding the features of the operating system and properly managing system resources. . You can learn KTU topics through our excellent research material including notes, presentations and final question papers, easily available on our website (www.keralanotes.com).
