Operating Systems: A Comparative AnalysisPOS/355Operating Systems: A Comparative Analysis Modern 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 a program, or the user, but are always there. During the course of this paper, Team “C” will compare and contrast several of the most prevalent operating systems. Some, like Windows, you may be familiar with. Others, such as UNIX or Linux are more obscure to the basic user. The main focus will be three of the most prevalent operating systems; MS Windows, UNIX based and Mac OS. These three systems represent the bulk of consumer focus, from the basic computer user to the IT professionalwith many realms 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 several aspects of each operating system, and compare them side by side. Team “C” will present an objective look into each topic, and 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. With each system boasting unique strengths and weaknesses, the search for the perfect system can now be matched to individual needs. 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 ManagementPurposeThe purpose of memory management is to arrange and efficiently schedule processes so that an Operating System can function. It uses techniques to allow it move and protect its memory when running its processes. It core function is to manage how the physical memory is handled and how the processes are executed. This optimizes the speed of the Operating system and ensures that all processes have an appropriate amount of resources assigned to them. ComponentsThe physical properties of memory are divided up into different types and speeds of memory. Also related to speed the cost per MB is higher for the higher speed memory. This means there will be larger size memory devices on the slower memory. Typically a system will have 3 different types. Each type also is configured for different speeds. The L1, 2, &3 cache are memory units that are placed very close to the processor and serves as the memory directly connected to the processor. These memory units are very fast and
