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.
This
paper highlights the major operating system concepts. It also covers
essential functions, the history of OS, with particular services and
an underlying computer system architecture. Major topics include
Process Control Blocks, CPU Scheduling, Threads, further notes on
Inter-process Communication, and several synchronization mechanisms,
such as Peterson's solution, Synchronization Hardware, Semaphores.
Besides these, it addresses highly complex issues such as the
Readers-Writers Problem, including descriptions of both abstract and
concrete solutions used for concurrent resource management.
Authored by Remzi H.
Arpaci-Dusseau and Andrea C. Arpaci-Dusseau, the book provides a full overview
of operating systems. It begins with virtualization and the basic process/needs
and scheduling then transitions into memory virtualization and management that
includes paging and segmentation. The book looks at concurrency-including locks,
condition variables, and semaphores. Other areas included are I/O devices, RAID
configurations, file system implementation, crash consistency, and distributed
systems. This is a comprehensive book ideal for anyone looking for essential
knowledge as well as advanced information on 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.
Marvin
Solomon's study notes outline the main topics of an operating system, which
include discussion on Java-related matters, processes, synchronization, and
memory management. Added to this is information about disk management, file
systems, and protection and security. This is a small brief report with
references in seeking knowledge for the essence of how an operating system
should be managed and work.
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.
