This note deals with what
operating systems are, and the context in which they operate. In particular, it
emphasizes the issues of software layers and abstraction, and the interaction
between the operating system and the hardware. Topics covered includes: Operating System Functionality,
Background on Computer Architecture, Processes and Threads, UNIX Processes,
Concurrency, Resource Contention and Deadlock, Lock-Free Programming, Memory
Management, File Systems, Mechanics of Disk Access, Crosscutting Issues, SMPs
and Multicore, Operating System Structure, Performance Evaluation, Communication
and Distributed Systems.
The notes go into great detail of how operating
systems have evolved and what kinds of operating systems exist today. The
content ranges from basic-level ideas such as system calls, OS structure, and
process management to important topics such as memory management, virtual
memory, page replacement algorithms, and the theory that describes how deadlocks
work, including detection, recovery, avoidance, and prevention. Both basic
concepts and more advanced practice issues are found in the discussion of
multiprocessor systems, I/O hardware and software principles, and file system
management, including implementation and optimization strategies. This document
proves to be very informative in terms of grasping the minute details of modern
operating systems.
Mrs.
Sk Abeeda's notes describe the basic concepts of the operating
system. The material includes processes, threads, and scheduling. It
gives a thorough view of such synchronization mechanisms and
deadlocks besides memory management. File and I/O subsystems and
protection mechanisms are also discussed, providing a comprehensive
view of how operating systems work and how they manage resources. In
short, it is a paper to allow one to gain a good grasp of the core
principles of operating systems and to put them into practice.
Lecture notes from Stanford University-cover a wide
spectrum of systems concepts- including threads and processes,
concurrency, and synchronization. The course also discusses several
scheduling methods, virtual memory, I/O, disk management and file
systems, network file systems, and security. Emphasis is placed both
on fundamental theories and leading-edge topics in operating
systems. This can be really useful when one wants to gain a good
grasp of the principles of classical and modern operating systems.
Andrew H. Fagg's
study note is an introduction to operating system internals. Aspects included
are OS fundamentals, C programming, bit-wise operators, file systems, and file
descriptors. The paper also tends toward the topic of processes, threads, and
synchronization with all-important aspects about OS functionality and
implementation from a practical viewpoint. This paper attempts to provide a
basic understanding of operating systems and their components.
The notes by Hugh Murrell provide a starting point in UNIX and operating
system theory. Key topics include: UNIX file systems, networking, and process
synchronisation. Inter-process communication under UNIX; including deadlock
scenarios and concepts of virtual memory and paging are also covered. A good
resource to explain both UNIX-specific features, as well as general operating
system principles.
The book of Max Hailperin exposes interaction in operating systems and
middleware, but with controlled support mechanisms. It entails threads,
scheduling, synchronization, deadlocks, and atomic transactions. It also has
virtual memory, process protection, persistent storage, networking, and
security. In this regard, it gives insights into both layers of operating
systems and additional software layers, showing a holistic view of controlled
interactions within computing systems.
