🔑 Key Concepts & Definitions

• 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.
