Correct Answer - Option 4 : Database management

The correct answer is Database management.

  • An operating system is a program on which application programs are executed and acts as a communication bridge (interface) between the user and the computer hardware. 
  • The main task an operating system carries out is the allocation of resources and services, such as the allocation of memory, devices, processors, and information.
  • The operating system also includes programs to manage these resources, such as a traffic controller, a scheduler, a memory management module, I/O programs, and a file system. 

  • Memory Management 
    • The operating system manages the Primary Memory or Main Memory.
    • Main memory is made up of a large array of bytes or words where each byte or word is assigned a certain address.
    • Main memory is fast storage and it can be accessed directly by the CPU. For a program to be executed, it should be first loaded in the main memory.
  • Processor Management 
    • In a multiprogramming environment, the OS decides the order in which processes have access to the processor, and how much processing time each process has.
    • This function of OS is called process scheduling.
  • File Management 
    • A file system is organized into directories for efficient or easy navigation and usage. These directories may contain other directories and other files.
  • Database management system (DBMS)
    • It is a software package designed to define, manipulate, retrieve and manage data in a database.
    • A DBMS generally manipulates the data itself, the data format, field names, record structure, and file structure.
    • It also defines rules to validate and manipulate this data.
