Operating System Foundations, Types, and Core Components
Begin with what an operating system really does, why it exists, how different OS types evolved, and which components form the heart of every modern operating environment.
Chapter 2Kernel, Boot Process, Interrupts, and System Calls
Understand how a machine starts, how the kernel gains control, how interrupts work, and how user programs request OS services through system calls.
Chapter 3Processes, Threads, Process States, and Context Switching
Learn how execution is represented inside the OS, how processes differ from threads, and why context switching shapes performance and concurrency.
Chapter 4CPU Scheduling, Dispatching, and Scheduling Algorithms
Study how the OS decides which task runs next and compare classical scheduling algorithms with practical system goals such as fairness, throughput, and responsiveness.
Chapter 5Synchronization, Critical Sections, Semaphores, and Deadlocks
Learn how concurrent tasks coordinate safely, why race conditions happen, and how deadlocks arise and are prevented.
Chapter 6Memory Management, Allocation Strategies, and Address Binding
Build a deep foundation in how operating systems allocate, protect, and organize memory for processes and the kernel.
Chapter 7Paging, Segmentation, Virtual Memory, and Page Replacement
Go deeper into virtual memory with pages, page tables, TLBs, faults, segmentation concepts, and replacement policies.
Chapter 8File Systems, Directories, Inodes, and Storage Management
Learn how operating systems organize persistent data, manage directories, map file metadata, and balance durability with performance.
Chapter 9I/O Systems, Device Drivers, Disks, and Interrupt-Driven Device Management
Study how the OS interacts with hardware devices, buffers I/O, handles disk scheduling, and uses drivers to support diverse peripherals.
Chapter 10Security, Protection, Access Control, and OS Hardening
Explore how operating systems enforce protection boundaries, manage permissions, defend resources, and support secure multi-user computing.
Chapter 11Inter-Process Communication, Signals, Pipes, Shared Memory, and Sockets
Learn how processes coordinate and exchange information using classic IPC mechanisms and why each one fits different workloads.
Chapter 12Linux Shell, Commands, Users, Processes, and Administration Basics
Turn theory into practical operating-system usage by learning everyday shell commands, process inspection, permissions, and system administration fundamentals.
Chapter 13Virtualization, Hypervisors, Containers, and Cloud Operating System Concepts
Connect classic OS concepts to modern infrastructure through virtual machines, hypervisors, namespaces, cgroups, and container runtime ideas.
Chapter 14Distributed, Real-Time, Mobile, and Embedded Operating System Ideas
Explore specialized operating-system domains where timing, distribution, battery, or hardware constraints change core design priorities.
Chapter 15Performance, Monitoring, Bottleneck Analysis, and OS Tuning
Learn how to observe an operating system, identify bottlenecks, and tune CPU, memory, storage, and process behavior in real environments.
Chapter 16Projects, Lab Practice, Interview Preparation, and Mastery Roadmap
Finish with a practical plan for mastering Operating System concepts through projects, revision, labs, debugging, and interview-oriented practice.
