Virtual memory uses disk space to emulate additional RAM, allowing the OS to run larger applications than physical memory alone would permit. This extends the available memory of the system.
The Round Robin scheduling algorithm is ideal for time-sharing systems as it equally divides CPU time across processes, ensuring fair allocation.
The kernel is the core component that handles resource management, process scheduling, hardware-device interactions, and system calls.
Multi-threading allows multiple threads to exist in a process, which reduces overhead compared to multi-processing and enables faster context switching between threads.
The ps command in Unix/Linux systems displays currently active processes, their status, and their associated resources.
ext4 (fourth extended filesystem) was developed for Linux and is widely used for its performance, reliability, and support for large partitions.
RAID (Redundant Array of Independent Disks) provides data redundancy and can improve performance by spreading data across multiple disks.
Microkernel architecture separates basic services, leading to increased system stability as each component operates independently minimizing failures.
Device drivers act as a bridge between hardware and operating system, enabling them to communicate effectively for device operations.
Memory protection ensures that different processes do not interfere with each other's memory spaces, maintaining process isolation.
