Topic 1 questions: Summary for topic 1: This topic gives the introduction to Windows and Linux. It explains about Virtualization. Linux is used on virtual machine which actually doesn’t exist. Virtualization is creation of virtual version rather than the actual one, such as storage system, network server or virtual operating system. It also defines the host OS and Guest OS. On which the virtualization software runs is Host OS and the one we want to play with is the Guest OS. The host operating

SELinux (Security-Enhanced Linux) was developed by the U.S National Security Agency and essentially enforces security policies that limits what a user or program can do by implementing MAC (Mandatory Access Control) in the Linux kernel. It defines a security policy that controls many different things such as files, devices, sockets, ports and even some processes. The Security-enhanced Linux's features are designed to enforce the separation of information based on confidentiality and integrity requirements

1. Compare between this two very popular Operating Systems, Windows VS Linux in terms of : a. Memory management 1. Focus on how both operating systems handle their memory management especially on virtual memory. To support your research, you may include relevant scenario of how memory being access. WINDOWS LINUX Your computer’s RAM has been combined with temporary space by virtual memory on your hard disk. Virtual memory moves data from RAM to a space called a paging file when RAM runs low. Moving

Twenty systems will initially be imaged for Linux and configured to run on the existing network environment. A testing group will be compiled from departments across the organization to determine how the operating system meets user needs in various departments. After a ten day testing period, any problems identified can be resolved as required to support a seamless transition. The phased migration can then be completed 50 systems at a time, cycling the Linux systems in and the XP systems out. As the

D. Major elements of memory management Linux operating system is using virtual memory to support programs running in the system. The virtual memory provides lots of optimal ways to maximize the memory mapping and utilization. The virtual memory can allocate much more memory to processes than its actual physical memory size. Linux provides virtual memory great support to allow the processes running in the system, such as mapping the process’s memory to physical memory (Arora, 2012). There are two

resources and provides common services for computer programs” (Wikipedia, 2017). We can know the notebook platforms are very important. Analysis Notebooks Platforms Today, we have four very practical notebook platforms. They are Windows, Mac OS, Unix and Linux. Windows system

normal programs in the system. In Linux scheduling is implemented by a class named sched_class (Seeker, 2013). The purpose of this class is to handle the multi-tasking processes by scheduler skeleton and data algorithms. As discussed above, the priority value is very important for the scheduling, so how the system set the priority in the Linux for assigning which is in higher priority? It depends on the types of the processes in data algorithms design of Linux. There are two types of the processes:

are stored, how to do things, the instruction codes to do everything. The system is in charge of security such as ensuring that unauthorised users do not access the system. There are many types of operating systems, a few are listed below: Windows Linux Mac OS/OSX Windows Windows is one of the biggest operating systems in the world and was created in 1981 by chase bishop. The purpose of windows is to improve on previous systems and make them all better. This operating system is a graphical

the organization will support the Linux platform and architecture. This makes a Linux implementation more cost efficient, because the Linux operating system is open source, allowing licensing for the operating system to be almost free, and maintenance quite minimal in cost, when compared to its Widows competitor. The implementation of Linux within the organization can also accommodate the use of several of their Windows based applications. WINEHQ – A unique Linux interface that gives Windows applications

command to view the current Linux Kernel parameters? The command that will allow you to see the Kernel parameters is sysctl –a. 2. What command can you run to list all the kernels available parameters one screen at a time with the ability to move forward and backwards on the output? The command that would you to do accomplish this would be the less /proc/modules 3. What is the purpose of enabling syncookies in the Linux Kernel? The purpose of enabling syncookies in the Linux Kernel is to help prevent
