The most common of all standard operating systems familiar to the common user is the Windows operating system. However, there are more to be explored such as UNIX, Linux and Mac OS. Whether it be hardware or software configurations, all operating systems have similarities yet stark differences in processing techniques. Let us explore and compare four system components within UNIX, Linux, MAC OS, and Windows in efforts of determining the independent and collective value whih all contribute to Information Technology. Memory Management As mentioned, there are four standard components of a computer system. Each consisting of a processor, main memory, I/O modules and a system bus [1] (Stallings, 2015, "Chapter 1, Basic Elements"). It is important to understand the role main memory plays in an operating system. One may think of it in terms of creating a document, relying on the operating system to perform intermittent saves of the document. If the cycle of document saving does not occur or if the user does not manually perform this function, the data is lost. This is the same aspect with a systems main memory. There is the risk of losing data if power to a system is lost. This will mean the difference in how well ones system will perform due to resource sharing. The system will run at peak performance or at a slower, degrading service level. Therefore, Memory management is a very critical task for all operating systems. Each operating system processes memory somewhat uniquely: UNIX –
