Pos/ Final Paper Compare Windows Linux Unix and Mac

...UNIX®/Linux® versus Mac® versus Windows® POS/355 October 29, 2012 Carol S. Eichling UNIX®/Linux® versus Mac® versus Windows® There are several computer operating systems available on the market, and it is sometimes difficult to choose. Therefore, it is important to compare the system capabilities to make the decision easier. The three biggest players in the operating systems market are UNIX®/Linux®, Mac®, and Microsoft® Windows® with Windows® holding the largest market share (Boitor & Brătucu, 2011). These three operating systems are capable of multi-processing and have similar capabilities; however, and it is important to compare and contrast how they handle memory management, process management, file management, and security, which are critical system functions. Discussing memory management, which is a vital component in operating systems, is first. Memory Management Memory management refers to the way a system makes use of the computer’s RAM (Random Access Memory). Many of the operating systems in use on computer systems have positives and negatives in their use of memory attributes. “Memory management is usually divided into three areas: hardware, operating system, and application…although the distinctions are a little fuzzy. In most computer systems, all three are present to some extent, forming layers between the user's program and the actual memory hardware” (Ravenbrook Limited, 2001, p. 1). There are several types of memory, including main memory, file system...

Evolution of the Universe

...UNIX, Linux, Mac, and Windows OS Comparison Paper B. James Bryant UNIX, Linux, Mac, and Windows OS Comparison In 1956, General Motors produced the first OS for its IBM 704 series mainframe. Since then companies around the world, both big and small, have been tirelessly researched, testing, and releasing newer and faster operating systems for the world to use. Among these are systems developed by/for UNIX, Linux, Microsoft, and Apple. In fact, it’s safe to say that these four companies have a monopoly on all current technology used in both the military, corporate, and private sectors all around the world. UNIX Operating System Unix operating systems have the ability to be multi-user, multi-tasking and portable. Multi-user capabilities are accomplished through time sharing which means the processor allocates slices of time to first one process and then the next, sharing the available time in sequence with waiting processes (Nagpal, 2009). Unix can run in either command line interface, CLI, or graphic user interface or GUI mode. A key and unique feature of Unix is that it has a modular design which allows parts of the system to be added or removed without affecting performance of the other parts making Unix systems highly customizable. Unix operating systems have four core components, (1) the kernel, (2) the shell, (3) the file system, and (4) the utilities or tools and applications (Love et al, 2005). The kernel is the lowest layer of the operating system that...

The History of Unix

...The Development of UNIX that prompted the creation of the GNU Operating System and the Linux Kernel Kyle Smoot Composition 1 Ms. Christine Kirsch 11/11/2010 The Development of UNIX that prompted the creation of the GNU Operating System and the Linux Kernel Without the Massachusetts Institute of Technology (MIT), the field of Information Technology would have never seen the development of UNIX, the GNU Operating System, or the Linux Kernel. The Development of UNIX The late 1950’s saw the rapid improvement of electronics. With this, it became apparent that computers would soon be able to time-share by switching back and forth between multiple users quickly. Fernando Corbato at the Massachusetts Institute of Technology (MIT) Computation Center led a team that created one of the first multi-user operating systems called the Compatible Time-Sharing System (CTSS) which was highly influential to the development of UNIX. (Diaz, Christopher, © 2007 ) In the 1960’s, AT&T Bell Labs, General Electric, and MIT conducted a joint research effort to build a next generation multi-user operating system called the Multiplexed Information and Computing System (MULTICS). The Bell Labs staff involved with MULTICS, including Ken Thompson, Dennis Ritchie, Joe Ossanna, and M. D. McIlroy, saw great potential in a communal environment enabled by a multi-user computer system, and they started looking for a way to preserve capability. In 1969, Thompson wrote a game on MULTICS called Space...

...| UNIX Performance Monitoring | My Research Paper | Student: Dwayne Blanchard Instructor: Professor Cliff KrahenbillAdvanced UNIX AdministrationMarch 3, 2012 | | | | | | The topic of my research paper will be on UNIX performance monitoring. The reason for choosing this topic is for personal understanding on how much UNIX performance monitoring differs from the monitoring of Windows based computers. This research paper is not to compare the two systems but to gain an understanding of how UNIX monitors performance. I don’t have any personal experience with working with UNIX systems, but as always eager to gain insight of different operating systems. The first thing I would like to discover is some of the common performance problems encountered caused by software, hardware and the combination of the two, the different terminologies associated with the processes via hardware or software, and finally what different utilities are used for monitoring these problems. We all know that UNIX has been around since the early 1970’s and the developments of performance tools have been around for a long time to enable system administrators in tuning systems for optimal performance. Operating systems performance problems normally involves process management, memory management, and scheduling. The object of performance on UNIX based systems is to determine the amount of time the operating system spends during scheduling...

...UNIX/Linux versus Mac versus Windows Rough Draft Annette Freshwater, POS355 November 4, 2013 Alicia Pearlman UNIX/Linux versus Mac versus Windows Final In today’s world of technology creation, development, and enhancement there are key factors to take into consideration. The choice of operating systems can determine the software and hardware utilized, the applications of the devices or programs, and determines the demographic, which will use the products. However the ever-changing field of technology has become more user-friendly, compatible, and more accepted in main stream than before. The main operating systems employed today are as follows: UNIX/Linux, Mac, and Windows. We will explore the various aspects of key components in these operating systems, memory, process, and file management along with the security of each system. The comparison of each system will determine the operating system best suited for the needs of our creations, projects, and improvements to the technology of the past, present, and future. MEMORY MANAGEMENT Memory management in multiprocessor systems is essential in executing several processes simultaneously. The multitasking of a system aids the user in accomplishing his or her task more efficiently than with a single processor system, which is important in the current climate of today’s multifaceted mix of professional and personal world.

...operating system is the ability to manage its memory. It is crucial for the operating system to be able to handle large amounts of information at the same time by using the processor, the RAM and the Hard Drive. Operating systems need a way to be able to allocate and de-allocate memory within the sectors of the RAM using the Kernel. However, every operating system handles this very differently. Let’s take a look at the differences between the three major operating systems and how they each manage its memory. We begin by analyzing UNIX/Linux. Linux, a form of UNIX, is very different in how it manages its memory to the other operating systems. Linux uses a tree like structure for memory management, and also using a numeric algorithm to make the best use of its valuable memory. The memory it manages is maintained in structures which enable protection of them by converting the list into the tree like structure. The tree is also balanced and not too much in depth. This helps for the information to be reached much more easily because it is closer for the processor to grab and use. It also cuts the time it takes for the processor to reach the data that would otherwise take longer to reach. The Virtual Address Descriptors marks the nodes within the tree as reserved, committed, or free. MAX OS works in a similar fashion to UNIX. Each task created within the MAC operating system has its own memory map. Within the operating system, the memory map mentioned before takes a form in to what...

Hacking Tips

...Number 1 Internet for Dummies -- skip this if you are a Unix wizard. But if you read on you’ll get some more kewl hacking instructions. ____________________________________________________________ The six Guides to (mostly) Harmless Hacking of Vol. 1 jumped immediately into how-to hacking tricks. But if you are like me, all those details of probing ports and playing with hypotheses and pinging down hosts gets a little dizzying. So how about catching our breath, standing back and reviewing what the heck it is that we are playing with? Once we get the basics under control, we then can move on to serious hacking. Also, I have been wrestling with my conscience over whether to start giving you step-by-step instructions on how to gain root access to other peoples’ computers. The little angel on my right shoulder whispers, “Gaining root without permission on other people’s computers is not nice. So don’t tell people how to do it.” The little devil on my left shoulder says, “Carolyn, all these hackers think you don’t know nothin’! PROOVE to them you know how to crack!” The little angel says, “If anyone reading Guide to (mostly) Harmless Hacking tries out this trick, you might get in trouble with the law for conspiracy to damage other peoples’ computers.” The little devil says, “But, Carolyn, tell people how to crack into root and they will think you are KEWL!” So here’s the deal.
