Option 2: The Differences in Memory Management between Windows® and Linux®.

Linux and Windows are both operating systems for the everyday computers. They both do not require special hardware. Many claim one operating system is better than the other. Windows does something better than Linux and Linux does something’s better than Windows. How each of these handles memory is the key to understanding.
Linux has the unique ability to virtually extend system RAM capabilities with another form of partitioning called SWAP space. SWAP space is used by Linux to add more virtual RAM to the system. Virtual memory sort of trick the system to think it has more memory that it actually has by sharing it between competing processes as they are desired. This speeds up the capability of Linux to operate faster and with less system resources than a Windows machine with similar RAM specs. This swap space is dedicated specifically for paging operations. Paging is the function of writing parts of memory chunks to temporary space on a hard disk.
Windows commonly uses a dynamically allocated temporary space on a hard disk called a “page file” for memory management. A “page file” is allocated on disk, for less frequently accessed objects in memory; things that would not necessarily be needed to be constantly in the hard drive or RAM memory buffer. This leaves more RAM obtainable to aggressively used objects.
Windows and Linux have modern memory management architecture that in reality have lot in common. Linux implements the virtual memory data structure in a similar manner to UNIX, which is the oldest operating system still in use today. The two systems may have originated differently but they are similar as well. Linux takes simplicity against performance while windows go for the monetary benefits. Which helps develop more features for windows but more difficult to maintain and improve.

...Memory Management Requirements The requirements that memory management is intended to satisfy are; relocation, protection, sharing, logical organization and physical organization. Main memory is vital component in a computer system, as both the operation system and some user application have to be loaded into main memory before they can be executed. I will describe each requirement is a bit more detail. The first requirement in memory management is relocation. Relocation is essentially relocating the process to a different area of memory. Often it is impossible for a programmer to know in advance which other programs will be resident in main memory at the time of execution of their program, therefore, in an effort to maximize processor utilization, we like to be able to swap active processes in and out of main memory. The next requirement in memory management is protection. The purpose of protection is to protect each process against unwanted interference by other processes, whether they are unintentional or deliberate. Since, the location of a program in main memory is unpredictable, it is impossible to check absolute address at compile time to assure protection. Furthermore, most programming languages allow the dynamic calculation of addresses at run time. Therefore, all memory references generated by a process must be checked at run time to ensure that they refer only to the memory space allocated to that process. Any protection mechanism must have the flexibility...

Memory Management

...Memory Management Week 1 - Individual Assignment Christopher Lewis - POS/355 - DATE \@ "MMMM d, y" March 31, 2014 Introduction Memory Management provides ways to dynamically allocate specific portions of memory to programs at their request and to free the memory for reuse, when it is no longer needed by the program that requested it, optimizing the overall system performance. Performance is optimized by carefully controlling and coordinating memory usage between Hardware, the Operating System, Applications, and Programs. There are five requirements that Memory Management is meant to satisfy, they are: Relocation, Protection, Sharing, Logical Organization, and Physical Organization. Memory Management, and its requirements, are vital to the success of an OS and are an essential part of a high performing, secure multiprogramming system. Memory Management Requirements Memory management must work to meet specific requirements to ensure uninterrupted operations. The requirements that must be met are: Relocation, Protection, Sharing, Logical Organization, and Physical Organization. The first requirement in memory management is relocation. Relocation is essentially relocating the process to a different area of memory. Often it is impossible for a programmer to know in advance which other programs will be resident in main memory at the time of execution of their program, therefore, in an effort to maximize processor utilization, we like to be able to swap active processes in and...

Master in Sport Science Department of Sociology and Political Science Faculty of Social Sciences and Technology Management Norwegian University of Science and Technology, NTNU Trondheim, Norway. 1 ABSTRACT Several indicators of social background and gender expectations are found to have an important impact on children’s physical activity patterns, yet few studies have explored intergenerational transfer of habitus through the use of triangulation of methods. The aim of this study is to explore how intergenerational transfer of habitus frames children’s opportunit to generate and negotiate physical activity in their everyday life. This is done by examining the relationship between children’s physical activity pattern’s and: parental capital, parental perception of gender appropriate sport, gender expectations, children’s housing, and children’s own experience with sports and physical activity in their everyday life. The empirical...

Financial Inclusion

...India The Case of Andhra Pradesh S Ananth, T Sabri Öncü Focusing on the institutional challenges to financial inclusion in Andhra Pradesh, this paper argues that it is the inability of formal financial institutions to meet the specific needs of the poor that has enabled informal service providers to fill the vacuum. Without a paradigm shift, especially on the part of banks, financial inclusion is bound to fall short of expectations. It proposes that the banking sector should look at efforts to expand inclusion not as a capital cost or as a charitable expense, but as a long-term investment in the future. The soundness of such an investment is borne out in the success of individual business correspondents in some districts of the state. 1 Introduction The views expressed in this paper are those of the authors and do not necessarily reflect views of the Centre for Advanced Financial Research and Learning. S Ananth and T Sabri Öncü (Sabrioncu.cafral@rbi.org.in) are with the Centre for Advanced Financial Research and Learning, Mumbai. Economic & Political Weekly EPW inancial inclusion has become central to Indian policymaking over the past few years and various attempts have been made to expand its scope. Despite these attempts, the challenges to financial inclusion remain formidable. These attempts and challenges have to be not only examined in the context of an increasingly globalised economy, of expanding markets, and of growing state intervention, but also of local variations...
