Final answer:
Heartbeat, time synchronization, and data exchange between parent and child partitions are examples of functions provided by an operating system.
Step-by-step explanation:
Heartbeat, time synchronization, and data exchange between parent and child partitions are all examples of functions provided by an operating system.
An operating system is a software that manages computer hardware and software resources and provides common services for computer programs. Heartbeat refers to the regular communication between components of a computer system to check their availability and ensure their proper functioning. Time synchronization is the process of coordinating the clocks of different devices to maintain accurate time across a network. Data exchange between parent and child partitions refers to the sharing of data between different sections or virtual machines within an operating system.
