The Kernel maintains context information for the process as a whole and for individuals threads within the process.

Scheduling by the Kernel is done on a thread basis.

Each thread belongs to exactly one process and no thread can exist outside a process. Threads have been successfully used in implementing network servers and web server.

They also provide a suitable foundation for parallel execution of applications on shared memory multiprocessors.

What will the user want to execute on that machine? The 3 types of Operating Systems commonly used nowadays are: (1) Monolithic OS, where the entire OS is working in kernel space and is alone in supervisor mode; (2) Modular OS, in which some part of the system core will be located in independent files called modules that can be added to the system at run time; and (3) Micro OS, where the kernel is broken down into separate processes, known as servers.

Some of the servers run in kernel space and some run in user-space. The execution of a process must progress in a sequential fashion.Most importantly, it directly has privilege access to the underlying hardware.Major components of an OS are file system, scheduler, and device driver.We are motivated by two closely related trends in hardware design: first, the rapidly growing number of cores, which leads to a scalability challenge, and second, the increasing diversity in computer hardware, requiring the OS to manage and exploit heterogeneous hardware resources.For more information, please read our documentation. See Section Download for information on how to obtain the code. We have posted a detailed list of changes on our mailing list.While the extend and depth of knowledge can be questioned, knowing more than the fundamentals can be critical to how well your program runs and even its structure and flow. When you write a program and it runs too slow, but you see nothing wrong with your code, where else will you look for a solution. An Operating System (OS) is a collection of software that manages computer hardware and provides services for programs.How will you be able to debug the problem if you don’t know how the operating system works? Specifically, it hides hardware complexity, manages computational resources, and provides isolation and protection.When one thread alters a code segment memory item, all other threads see that. Threads provide a way to improve application performance through parallelism.Threads represent a software approach to improving performance of operating system by reducing the overhead thread is equivalent to a classical process.Any application can be programmed to be multithreaded.All of the threads within an application are supported within a single process.
