UNIX/Linux, Mac, Microsoft Windows Operating System Differences University of Phoenix Abstract This paper will elaborate on the major differences of the main Operating Systems (OS), which are UNIX/Linux, Mac®, Microsoft® Windows®. The areas of discussion for this paper will be on Memory Management, Process Management, File Management, and Security for each operating system. Operating Systems (OS) for a computer is the main processing software program used to allow the computer processor to communicate with the software and hardware I/O devices. Computers as SUN, SUSE use UNIX/Linux operating system, Mac® (Macintosh) computer uses Apple operating system, and Personal Computers (PC) …show more content…

Mac is a personal computer usage environment not needing as much memory for operating system, but for the software execution and data storage. Windows is also a personal computer environment with a server type environment growing in use. This memory management is both needing large sections of memory for data and operating systems transferring. Along with the processor speed, memory management is one of the most important parts of computer operation. The operating systems also rely on process management. Computers today have developed from running single program capability and running run one program at a time to having the ability to run multiple programs at the same time. They are also able to use multiple threads to provide more than one task to be run at the same time. Processes were created to help manage the execution of the programs. A process is defined as a unit of work in a modern time-sharing system during the execution of a program. There are five states that a process may be in new, running, waiting, ready, and terminated. Only one process can be running on a processor and the other processes are in a ready and waiting state. Operating systems use processes to execute the system code, which executes and runs the main programs to process and operate the computer. Operating systems may use the state of a process in different ways. A process
