There are several page replacement strategies discussed in this book, these methods are known as Random, First-In-First-Out, Least-Recently-Used, Least-Frequently-Used and Not-Used-Recently. The Random strategy randomly selects a page in main memory for replacement, this is fast but can cause overhead if it selects a frequently used page. FIFO removes the page that has been in the memory the longest. LRU removes the page that has been least recently accessed, this is more efficient than FIFO but causes more system overhead. LFU replaces pages based onShow MoreRelatedComputing And Information Technology Programmes Essay1436 Words   |  6 PagesCLI 5 System Requirements 5 Windows Server 2008r2 5 Oracle Solaris Server 11.2 5 4.

The most useful and better approach is divide the task into small components /modules instead of having one monolithic system so that the operating system can function properly and can be modified easily. Input, output and functions should be clearly defined in each of the system modules as far as we can finally come with large and complexRead MoreLinux Operating System Resembles Unix Operating. System1124 Words   |  5 PagesLinux operating system resembles UNIX operating system a lot but they are not same. They are two different operating systems. Linux operating system is created by considering UNIX as basis. It is not only advanced in operating system development but it is also more powerful and easily available to users. It is an open source software. Unlike any other operating system, user can take Linux and modify the configurations of operating system as per their requirement. Like windows operating system, LinuxRead MoreVirtual Machines Essay1840 Words   |  8 Pages(1)Virtual Machines The fundamental idea behind a virtual machine is to remove the hardware of a single computer and make it a self-contained operating environment that behaves as it is a separate computer. Essentially, the virtual machine is software that executes an application and isolates it from the actual operating system and hardware. CPU scheduling and virtual-memory techniques are used so that an operating system can create the illusion that a process has its own processor with its ownRead MoreOperating System Structure Of A Single Large Executable Binary Program2163 Words   |  9 Pages OPERATING SYSTEM STRUCTURE The operating system can be defined as a collection of written procedures, linked together into a single large executable binary program.

The operating system mainly divided into two such as application software and operating system software.Application software are the different task such creating s/w for banking, customer query, creating website etc. the operating system software duty is to manage the task which the application software provides. This task can be handled by operating system software with the help of kernel. 2. KERNAL Kernel is the heart of operating system.

The OS is the most important software running on a computer because it handles the memory, processes and all of its software and hardware. The OS helps coordinate all the programs that can access your CPU, memory and storage so that each program gets what it needs. Without the operating system a computer and its software would be completelyRead MoreChapter 5 Of The Windows Internals Textbook1076 Words   |  5 PagesWindows Internals, Part 1, 6th ed, Chapter 5 Chapter 5 of the Windows Internals textbook written by Mark Russinovich, David Solomon and Alex Ionescu covers Windows processes, threads, and jobs. This chapter goes over how processes are managed, describes the kernel mode and user mode, and process blocks. One of the topics I am covering for my final is the similarities and differences between processes and threads in Windows and FreeBSD so this source will help provide information about the properties
