Final answer:
The OS maintains system stability and security by preventing interference between processes through protection mechanisms like permissions, user accounts, and process isolation.
Step-by-step explanation:
The Operating System (OS) is pivotal in resource management and safeguarding a computer's stability and security. It achieves this through crucial protective measures, preventing processes from unauthorized interference. Mechanisms like permissions, user accounts, and process isolation are employed to restrict access to memory spaces and resources, thwarting conflicts, data corruption, and security breaches.
The OS plays a critical role in ensuring each process accesses only authorized resources, thereby maintaining system integrity and preventing potential disruptions. This robust protection framework is indispensable for the seamless functioning of a computer system.
