What are the key components of memory management?

Allocation and deallocation, virtual memory, memory protection, and garbage collection.

What is allocation and deallocation in memory management?

The OS assigns memory space to different processes and deallocates it when no longer needed, ensuring efficient use of available RAM.

What is virtual memory in memory management?

Virtual memory extends the system's memory by using disk storage when physical memory is insufficient, swapping data between RAM and disk.

What is memory protection in memory management?

The OS ensures that processes do not access the memory space of other processes, preventing data corruption or security issues.

What is garbage collection in memory management?

The OS or programming environment automatically reclaims memory that is no longer being used by a process, preventing memory leaks.

What are the key components of storage management?

File system management, disk scheduling, and data integrity.

What is file system management in storage management?

The OS manages how data is stored, organized, retrieved, and maintained on storage devices, handling file permissions, access control, and directory structures.

What is disk scheduling in storage management?

The OS decides the order in which disk I/O operations are performed to minimize seek time and improve efficiency.

What is data integrity in storage management?

The OS ensures that data stored on disks remains accurate and uncorrupted, even during system failures or power outages.

What are the key components of I/O device management?

Device drivers, interrupt handling, and buffering and spooling.

What are device drivers in I/O device management?

Device drivers are used by the OS to communicate with hardware peripherals, acting as intermediaries between the OS and the physical device.

What is interrupt handling in I/O device management?

The OS manages I/O interrupts, signals sent by hardware devices to indicate they need attention, responding to handle I/O efficiently.

What is buffering and spooling in I/O device management?

Buffering temporarily stores data before sending it to a device, while spooling queues data for a device that cannot handle multiple tasks simultaneously.

What are the key components of network resource management?

Bandwidth allocation, connection management, and security.

What is bandwidth allocation in network resource management?

The OS manages network bandwidth, ensuring processes or users can send and receive data over the network without congestion or delays.

What is connection management in network resource management?

The OS handles network connections, managing multiple simultaneous connections, establishing, maintaining, and terminating connections as needed.

What is security in network resource management?

The OS manages network security through firewalls, encryption, and protocols to ensure data transmitted over the network is secure.

What are the key components of power and energy management?

Power efficiency and thermal management.

What is power efficiency in power and energy management?

The OS manages power consumption, adjusting CPU speed, turning off inactive components, and putting the system into low-power states to conserve energy.

What is thermal management in power and energy management?

The OS monitors the system’s temperature and manages cooling to prevent overheating.

What are the key components of security and access control?

Authentication, access control, and resource isolation.

What is authentication in security and access control?

The OS ensures that only authorized users can access the system by managing login credentials and password protection.

What is access control in security and access control?

The OS enforces policies that restrict access to files, processes, and devices based on user roles and permissions.

What is resource isolation in security and access control?

The OS isolates processes and their resources from each other to prevent interference, ensuring system stability and security.

What are the key components of deadlock and concurrency management?

Deadlock prevention and concurrency control.

What is deadlock prevention in deadlock and concurrency management?

The OS uses strategies to prevent deadlock situations, where multiple processes block each other by holding resources and waiting for others to release them.

What is concurrency control in deadlock and concurrency management?

The OS manages multiple processes running simultaneously, ensuring they access shared resources without conflicts.

What are the key components of resource monitoring and optimization?

Performance monitoring and load balancing.

What is performance monitoring in resource monitoring and optimization?

The OS constantly monitors system performance and can optimize the allocation of resources based on real-time needs.

What is load balancing in resource monitoring and optimization?

In multi-processor systems or distributed environments, the OS can balance workloads across CPUs or nodes to ensure even distribution of resource usage.

What is the role of the operating system in resource management?

The OS handles the scheduling, allocation, and monitoring of resources across processes, users, and devices to ensure smooth and efficient operation.
