Virtual machine (see source): A user interface created by system software that presents a simplified, friendly environment for interacting with hardware resources, often by simulating hardware resources to the user.
System software (see source): A collection of programs that manage computer resources and act as an intermediary between the user and the hardware, facilitating easier and safer access to system functions.
Operating system (see source): The most critical type of system software that controls the overall operation of the computer, manages hardware and software resources, and provides services to other system programs and users.
Language services (see source): Programs such as assemblers, compilers, and interpreters that translate high-level or assembly language programs into machine language, enabling easier program development and execution.
Memory managers (see source): System software responsible for allocating, retrieving, and managing memory space for programs and data, ensuring efficient use of memory resources.
