Operating Systems: A Comparative AnalysisPOS/355Operating Systems: A Comparative AnalysisModern electronics are present in many aspects of everyday life. From cell phones to business servers, these electronics need an operating system. Most of these operating systems are present in even if they are not evident. Many of them are embeddedinto or electronics, hidden from our view. These operating systems control how our electronics react to the program, or the user, but are always there. This paper will compare and contrast a few of the most prevalent operating systems. Some, like Windows, most possess some familiarity. Others, such as UNIX or Linux are more obscure to the average user. The focus will be three of the most prevalent operating systems; MS Windows, UNIX based and Mac OS. These three systems represent the bulkof consumer focus, from the foundational computer user to the IT professional with manyrealms to safeguard. From cell phones to business driven server systems, operating systems play a vital role in not only our daily lives, but the economy, as well. Understanding the differences between these systems can assist everyone, whether you are shopping for your home or a multi-million dollar corporation.The comparative analysis will look at various aspects of each operating system, and compare them side by side. It will present an objective look into distinct functions and examine how each operating system addresses those facets. These topics represent a
technical look at each system. However, these areas define each system and, therefore, must be the focus when contrasting these operating systems side by side. Every business and consumer must make a choice when approaching an operating system. As each operating system possesses unique strengths and weaknesses, the search for a system that matches the needs of the individual is attainable. With this guide, you will now have a tool to find your perfect system. Where the differences exist, are fundamental matters of priority, context, and opinion.Memory ManagementMemory management is important for any operating system. Its purpose is to optimize the hardware attached to the system. Memory management techniques differ by operating system. Depending on the system, it will handle its hardware differently. The efficiency of the system can greatly depend on proper memory management. It is oneof the key elements of the system.HardwareThe hardware you will find on a system is comprised of temporary memory calledRAM and a permanent memory that resides on the hard disc drive, or HDD. The RAM, or random access memory, is a fast memory. This is where the processes are stored while awaiting action by the processor. The system design risks compromise if the memory sizeis improper for the tasks that require performing. “Early computers used the two-level storage system consisting of main memory and secondary memory” (George Mason University, n.d.). These were dedicated memory cores. Systems were limited to the memory that was available. T
