Which one among the following is not included in the basic functions of operating system ?

An Operating System (OS) acts as an intermediary between the user and hardware, performing several core resource management tasks. Basic functions include Process Management (often referred to as Job Scheduling), which manages the execution sequence of processes for efficient CPU utilization [t1][t3]. Memory Management is another fundamental role, involving the allocation and deallocation of main memory to various processes [t2][t9]. Job Control is a traditional function, particularly in mainframe and batch systems, where the OS manages the lifecycle and sequencing of jobs [t1]. While an OS manages files and I/O devices, 'Data Management' is typically considered a function of a Database Management System (DBMS) or specific application software rather than a core, basic function of the operating system itself. The OS provides the file system structure, but the high-level management of data content and relationships is handled by specialized software [t6][t7].
