Question

BlackTom AI · Accepted Answer

The question asks about an operating system that coordinates multiple independent computers and makes them behave as a single coherent system.

Option a: 'Batch OS' refers to an operating system designed to execute a sequence of jobs in batches, typically on a single machine, without distributing tasks across a network. It does not imply inter-machine coordination to present a unified system, so this is not correct.

Option b: 'Mobile OS' describes an operating system for mobile devices. While mobile OSes manage resources on a single device, they do not inherently provide the orchestration of multiple independent computers as one system, so this choice is incorrect.

Option c: 'Distributed OS' is specifically defined as an operating system that manages a group of independent computers and makes them appear to the user as a single coherent system. This aligns directly with the concept described in the question, so this option is correct.

Option d: 'Real-Time OS' refers to an OS designed to guarantee timing constraints for tasks, often in embedded or time-critical environments. Although it may be used on individual machines, it does not describe the aggregation of multiple machines into a single system, so this is not the right choice.
