In computer science, a runtime support service is a service that provides support to an application program while it is running. It is a set of software components that enables a program to run and perform various tasks while it is executing.
These services may include memory management, process management, input/output management, and network management. The primary function of a runtime support service is to provide an environment in which an application can execute and access system resources in a safe and efficient manner.
For example, in a cloud computing environment, the runtime support service may include the following components:
Virtual machine monitor: It provides the necessary virtualization support to the virtual machines running on the host system.
Memory management unit: It manages the memory resources of the virtual machines and ensures that each virtual machine has access to the required amount of memory.
Input/output manager: It manages the input/output operations of the virtual machines and provides them with access to the physical devices.
Network manager: It manages the network connectivity of the virtual machines and provides them with access to the network resources.
Overall, the runtime support service plays a critical role in ensuring the proper functioning of an application program and the efficient utilization of system resources.
