System software CST 305 of the KTU S5 2019 scheme is one of the core courses. The purpose of these KTU notes is to create awareness about the low-level codes which are very close to the hardware and about the environment where programs can be developed and executed. This course helps the learner to understand the machine-dependent and machine-independent system software features and to design/implement system software like assembler, loader, linker, macro processor and device drivers. The study of system software develops the ability to design interfaces between software applications and computer hardware.
You need to understand Data Structures, and Computer Organization before taking the notes for KTU Computer science S5 system software which is provided according to the 2019 scheme.
