Key Points

• Command Line Interface(CLI) -  A command-line interface (CLI) is a text-based interface used to enter commands. It is used to run programs, manage computer files and interact with the computer. Command-line interfaces are also called command-line user interfaces, console user interfaces and character user interfaces.In the early days of computing, before the mouse, it was the standard way of interacting with computers. While the graphical user interface (GUI) has largely replaced the command-line interface (CLI).

Additional Information

• There are many different types of command-line interfaces each command-line interface uses its own command syntax, but they all function in a similar way.

The correct answer is Application

Key Points

• An application, or application program, is a software program that runs on your computer. Web browsers, e-mail programs, word processors, games, and utilities are all applications. The word "application" is used because each program has a specific application for the user.
• In contrast, system software consists of programs that run in the background, enabling applications to run. These programs include assemblers, compilers, file management tools, and the operating system itself. Applications are said to run on top of the system software since the system software is made of "low-level" programs. While system software is automatically installed with the operating system, you can choose which applications you want to install and run on your computer.
• Macintosh programs are typically called applications, while Windows programs are often referred to as executable files. This is why Mac programs use .APP file extension, while Windows programs use the .EXE extension. Though they have different file extensions, Macintosh and Windows programs serve the same purpose and can both be called applications.

The correct answer is Database management.

Key Points

• 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. 

Additional Information

  • 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.
