Introduction to Operating Systems by Dr. Mark Humphrys
This note
describes the following topics: UNIX or Linux, Pipes and redirection, Text
editors, Case sensitivity, Filenames and Special Characters, UNIX file
protections, UNIX directory protections, Shell, Shell utilities, Search engine,
PC operating systems, Server operating systems, Mobile operating systems, OS
structure, Processes, Memory, Files, Windows command line.
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.
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.
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.
The Notes by Bighnaraj Naik
hence, provide a directed discussion of operating systems, beginning with their
history, and various types. The paper deals with critical services to an
operating system in connection with management of processes, the idea of process
synchronization, in-depth process management and scheduling, tools and
constructs used in processing concurrency, detection of deadlocks, and
prevention techniques. The paging technique and virtual memory management form
the base of dynamic resource allocation techniques. File systems have also been
discussed; they classified into logical and physical file systems with
differences in their allocation strategies, so it has provided a profound
insight into the theoretical and practical sides of the operating system.
