...Microsoft Windows, and MacOS systems. In particular we will contrast and compare the different operating systems in regards to memory management, processing, file management and security. Operating systems at the core is all about the kernel. The kernel in all of the operating systems is the main component that is responsible in the management of memory, processing, file management and security. Contrast and Comparison of Memory Management within Operating Systems Memory management in comparison and contrasts between the different operating systems is due to the way the kernel works in conjunction with the memory. Since each operating system has different kernel’s they each have similar and different ways that they manage memory. Contrasts and comparisons on Mac OS, Windows, and UNIX/Linux are described below. 1. UNIX: Though UNIX and Linux are extremely similar when it comes to how things work internally; there are slight differences that make UNIX distinct from its counterpart. One process that UNIX utilizes is known as swapping; this is done by moving chunks of the Virtual Memory (called pages), out of the main memory and moving others in. In order for this process to work at its best, those pages that are needed must be accessible in the Main Memory at the demand of the CPU. When a page is expected to be needed in the very near future it is termed a resident set. If the CPU attempts to access a page that is no longer available in the Main Memory, a page fault will occur...

...different parts to types of memory, primary, also referred to as main, and secondary. The former has two parts, one part for the kernel, which is reserved for the operating system, and the other part for the programs currently being executed. Memory management units must work efficiently in transferring information between primary and secondary. In order for this to succeed, there are a few requirements that memory management units must meet in order to fulfill the demands of users. Memory management units require relocation, protection, sharing, both local and physical organization, among processes in both primary and secondary memory. Two examples of operating systems that meet these requirements, but yet both manage memory differently are Windows and OS X, which is used by Macintosh as an operating system. Since main memory is shared among different types of processes, it is very difficult for a programmer to tell which processes will be in main memory at the time of execution. In order to fully maximize processor utilization, it would be beneficial to be able to swap active processes in and out of main memory providing a broader spectrum of ready processes to execute. If a program is swapped out into a hard disk from main memory, it would be very...

...Size), the amount of virtual address space used, and other tidbits. Within the memory descriptor we also find the two work horses for managing program memory: the set of virtual memory areas and the page tables. Gonzo’s memory areas are shown below: Kernel memory descriptor and memory areas Each virtual memory area (VMA) is a contiguous range of virtual addresses; these areas never overlap. An instance of vm_area_struct fully describes a memory area, including its start and end addresses, flags to determine access rights and behaviors, and the vm_file field to specify which file is being mapped by the area, if any. A VMA that does not map a file is anonymous. Each memory segment above (e.g., heap, stack) corresponds to a single VMA, with the exception of the memory mapping segment. This is not a requirement, though it is usual in x86 machines. VMAs do not care which segment they are in. A program’s VMAs are stored in its memory descriptor both as a linked list in the mmap field, ordered by starting virtual address, and as a red-black tree rooted at the mm_rb field. The red-black tree allows the kernel to search quickly for the memory area covering a given virtual address. When you read file /proc/pid_of_process/maps, the kernel is simply going through the linked list of VMAs for the process and printing each one. In Windows, the EPROCESS block is roughly a mix of task_struct and mm_struct. The Windows analog to a VMA is the Virtual Address Descriptor, or VAD; they are...

...using which processes can run even when they are not entirely in memory. Main memory is treated as an array of pages thus separating in to logical memory and physical memory, thus the size of the physical memory is not a limitation for the user. Memory management in Windows The physical memory in Windows is divided into a number of physical pages .If the pages are divided in to say 4KB size causes external fragmentation of memory. If the pages are divided into 2MB pages this causes internal fragmentation. Windows uses large pages to better the performance of translation look aside buffer TLB( is a cache used by memory management hardware to improve virtual address translation speed).The physical pages are in one of the following states free page, zeroed page, modified page, standby page ,bad page, transition page, valid page. Valid pages are in processes page tables ,while pages in other states are separated in to list based on their state. Virtual memory in Windows is implemented by demand paging with clustering. Demand paging is method in which the pages are loaded in to the memory as they are required in the course of the process’s execution. Clustering is used by Windows in this when there is a page fault (page is required for the further execution of the process) along with the page ,many other pages are also moved in to the physical memory. The free pages are handled by the virtual memory manager. Every process has a working set minimum(it is the minimum number of...

...REFERENCES File System Definition: Computers use particular kinds of file systems to store and organize data on media, such as a hard drive, the CDs, DVDs, and BDs in an optical drive or on a flash drive. Any place that a PC stores data is employing the use of some type of file system. A file system can be thought of as an index or database containing the physical location of every piece of data on a hard drive. A file system is setup on a drive during a format. 1) In a computer, a file system (sometimes written filesystem) is the way in which files are named and where they are placed logically for storage and retrieval. The DOS, Windows, OS/2, Macintosh, and UNIX-based operating systems all have file systems in which files are placed somewhere in a hierarchical (tree) structure. A file is placed in a directory (folder in Windows) or...

...NT1210: Introduction to Networking_V1.0 | Virtual Computing | Comparing Microsoft and VMware solutions | | Jacob D. Smith | 10/21/2015 | | With so many features called by differing names in each virtualization platform, comparing Microsoft and VMware virtualization solutions can sometimes seem a bit like comparing apples and oranges. But, I’ll try to boil things down to a real-world perspective based on my experience implementing both solutions in the field throughout my career. In this article, I’ll provide a summarized comparison of the feature sets provided by each of these latest releases using the currently available public information from both Microsoft and VMware as of this article’s publication date for additional reference. How to compare? Rather than simply comparing feature-by-feature using just simple check-marks in each category, I’ll try to provide as much detail as possible for you to intelligently compare each area. As I’m sure you’ve heard before, sometimes the “devil is in the details”. For each comparison area, I’ll rate the related capabilities with the following color coded rankings: * Supported – Fully supported without any additional products or licenses * Limited Support – Significant limitations when using related feature, or limitations in comparison to the competing solution represented * Not Supported – Not supported at all or without the addition of other product licensing costs In this Essay, I’ve organized...

...Fault Tolerance Disaster Recovery Kevin Bowman POS/421 Jeffery Comrie University of Phoenix April 15, 2013 In the world of Information Systems and network administration, there comes a time when system administrators and developers have to take into consideration the possibility of critical system failure which could lead to complete data loss. When it comes to technology and equipment the question is never if it fails rather when it fails. “Regardless of how bulletproof the design is, how fault-tolerant the system, or how well trained the operators and technicians, system failures are still possible.”(Witt, 2009) In the event the system does fail either by, disk failures, administrative errors, natural disasters, or unauthorized changes to data, a recovery plan must be in place to minimize downtime. In the scenario as described for Kudler Fine Foods, there would be a backup drive at each location, where daily backups of data will take place and those backups will be stored on a tape drive that way information is not lost at any time and stored offsite. The files would be stored off site in the event there is a natural disaster or fire or some other catastrophic event to take place that actually destroys the servers and hard drives, the tape drives being stored offsite preserves the data once a new server is in place. Data redundancy is a key aspect to recovering from such system failures. In the case of restoring Active Directory Directory Services in the event...

...the proper installation of Microsoft’s Cluster Server and several of Microsoft’s cluster-aware applications. He follows this with a brief discussion of disaster-tolerant architectures, and concludes with a case study. High-Availability Topics Rupani begins with a definition of several high-availability concepts, such as planned and unplanned outages, single points of failure, mean time between failures and interruptions, fault tolerance, and redundancy. He then provides an overview of several important high-availability technologies. RAID RAID technology is the most common method to provide data resiliency. With RAID (Redundant Arrays of Independent Disks), data is redundantly stored on multiple disks such that, should one disk fail, the data can still be reconstructed. RAID arrays typically provide a hot-swappable capability so that a failed disk can be replaced without taking down the array. There are several configurations of RAID. Most stripe data across multiple disks to achieve improved performance. Mirrored disks, used by fault-tolerant systems and designated as RAID 1, provide an entire copy of the database on a backup disk. The most common form of RAID in use today is RAID 5, which provides one additional disk and which stripes data and parity across disks. Since there is one extra disk, the data can be reconstructed should any one disk fail. There are several other forms of RAID designated as RAID 0, 2, 3, and 4, and combinations of these. Rupani...

...NETWORKS AND TELECOMMUNICATONS A FULLY FUNCTIONAL NETWORK DESIGN FOR SHELLY FASHION PRESENTED BY: Osazuwa Olufemi George Business requirement Shelly fashion is a clothing boutique that sells clothes to both male and female customers. Their goal is to be the biggest retail clothing store in the country which aims to provide customers from the ages of 5 to 45 years of age a wide variety of quality clothing. The clothing retail store is open six days a week to customers who come in and buy their clothes directly at the store. The transaction is recorded and stored on the store’s computer with a Store Management Software which keeps track of inventory, sales, and computes the profits of the retail store biannually. Shelly fashion is looking to expand its reach using internet technology so it would be able to meet with the growing number of customers and also to connect all its other and future branches together to form a centralized network. With the network the retail store would be able to launch its home delivery option where customers would be able to buy clothes online and have their goods brought to them at their homes without having to be physically present at store. The business owners want to embark on a project to set up a telecommunications network which should be able to reach their business requirements. Shelly fashion’s business requirements for the proposed network are as follows: * Reduce operating cost by cutting cost too make telephone calls...

...which is the understanding that all parties agree on the content of the contract before it is finalised. The parties must also have the intention to be legally bound and must be in a legal capacity to enter into the contract. In this case I do not believe there is a contract as the shop keeper had the golf clubs in the window, and this meant the difference between an “offer” and a “willingness to negotiate”. This would mean that when the customer entered the shop and stated that he would like to purchase the golf clubs the contract had not been formed, because the shopkeeper is well within his rights to refuse the customer, even though the shopkeeper had the product in the window for purchase. This would not be the case if the product in the window had been labelled as an offer, in which case the customer could then enter the shop and agree to the offer. So, the golf clubs in the window was merely a willingness to negotiate. The same can be said for the legal case Pharmaceutical Society of Great Britain vs Boots the Chemists (1952). This is a case where determining the point of the “sale” was crucial. In this case it was determined that the goods on display within the pharmacy were a willingness to negotiate and not an offer, and there was only acceptance when the customer took the product to the register to pay and the pharmacist then agreed to sell that product to the customer. Because of laws that require listed poisons to be supervised by a registered pharmacist, that sale...
