Cheat Sheet
- Process Management & Scheduling Fundamentals -
Processes transition through states - New, Ready, Running, Waiting, Terminated - as detailed in Tanenbaum's Modern Operating Systems. Major CPU scheduling algorithms like FCFS, SJF, and Round Robin (tuned with a time quantum, e.g., 20 ms) impact throughput and turnaround time, computed as Σ(turnaround time)/n. A memorable tip is "First Come, First Served" for FCFS and "Shortest Job Next" to recall SJF.
- Memory Allocation & Virtual Addressing -
Operating systems use paging and segmentation to allocate memory safely; calculate any virtual address with VA = (page number × page size) + offset. Segmentation offers logical division of code and data, while paging avoids external fragmentation entirely. Remember the "PSO" formula (Page Size × Number) to decode addresses quickly on a basic operating system questions section.
- Page Replacement Algorithms & Thrashing -
Page replacement algorithms decide which page to evict on a fault: FIFO uses a simple queue, LRU evicts least recently used pages, and the Optimal algorithm sets the performance ceiling. Watch out for Belady's Anomaly, where adding frames can paradoxically increase page faults under FIFO. A quick mnemonic "FLO" (FIFO, LRU, Optimal) helps fix the order in mind during an operating system quiz.
- Concurrency Control & Deadlock Strategies -
Synchronization primitives like semaphores and mutexes enforce mutual exclusion and coordinate threads, as outlined in Silberschatz's Operating System Concepts. Deadlock requires four conditions - hold-and-wait, mutual exclusion, no-preemption, circular-wait - and negating any one prevents it; alternatively, the Banker's algorithm can maintain a safe resource allocation state. Recall the acronym "HENC" (Hold-and-wait, Exclusion, No-preemption, Circular-wait) to spot deadlock prerequisites quickly in OS quiz online or operating system trivia.
- File System Structures & Access Methods -
File systems manage data using inodes (Unix) or a File Allocation Table (FAT), each mapping metadata to disk blocks. Allocation methods - contiguous, linked, and indexed - balance performance against internal and external fragmentation, with indexed allocation using pointer arrays for direct block access. When reviewing file system trivia, picture an "inode highway" branching into data blocks to visualize indexed pointers instantly.
