By free, you can download, modify and redistribute it without spending a dime! Linux is a younger player in the OS world, having been written in , and is optimized for modern use well, more than Windows and Mac. Unfortunately, it has some disadvantages also No offence. There are hundreds of differences which can't be explained here however windows is GUI and user friendly and very popular as compared to LiNUx which is good using command line, of course now Linux is coming with GUi but Linux is good only if we use Commands, Linux is fast, secure, looks great, don't have to reboot it everytime like windows systems, I have seen Linux servers running for days and more without any issues.
There are many more pros than con's I can give on Linux. Not used MaC -but another powerful machine which is I guess based on Linux and with amazing processing capability and excellent performance and GUi. Products By Bayt.

Huge quantity of function: When you get to know Windows well, you'll find out that there are so many functions that you can do almost anything quite easily.
Windows Vs Linux Vs Mac for Dev
Cons: Viruses: You may need to buy an antivirus program, although free ones exist. Slow: Windows, especially Vista and 7, requires a lot of computer resources memory, processor, disk space , and thus, runs slower. Price: It easily costs over a hundred dollars. Pros: Viruses: Apple Macs get almost no viruses. This is mostly due to Window's superior market share. Reliability: Macs only run on Apple computers, and are thus less prone to hardware and software crashing. Looks: Let's face it, most of the time, Mac just looks better than Windows.
Linux vs Mac OS: 15 Reasons Why You Must Use Linux Instead of Mac OS
Memory sharing is when multiple programs need to access the same portion of memory. Proper management of memory ensures that this happens without hindering the performance of the system. Relocation involves moving programs between virtual memory and physical memory. To maintain optimum performance, a process will be swapped out while another process executes and then the initial process will be swapped back in but at a different location in the memory. Organization is a key component in memory management because some blocks of memory need to be accessed quicker than others. Linux 3 available.
The two main components of RAM are physical memory and virtual memory. Physical memory is the actual amount of memory installed on a computer and is commonly 64 or megabytes. This is not enough memory to run all the programs on a computer, so a technique called virtual memory is used. According to "Windows. The concept of virtual memory is based on virtual addresses.
When data is stored in virtual memory, it is assigned a virtual address that maps to a physical address. So, when the virtual address is called it is translated into a physical address through the use of page tables.

This process of calling memory is known as paging. Now that some of the basic components of memory management have been explained, let us take a look at how each of the systems being compared manages its memory. First there is Mac. Mac groups memory into four categories: free memory, wired, active and inactive. Wired memory is used by the kernel and cannot be swapped in and out. Active is memory currently being used and inactive was recently used and stored so that it can be accessed quickly.
Through the use of virtual memory, Mac allocates up to 4 gigabytes GB for each process.
In comparison, Windows and Linux allocate the same amount, but specify where the 4 GB will go. The kernel will assign each process its own address space and control the access of the address spaces. However, some sharing within the OS X system is still possible such as with libraries and framework. Both Linux and Windows allow for memory sharing. Windows allows multiple processes to share memory through the use of file mapping.
Linux uses a slightly different method to share memory. To share memory, one process must allocate the segment. Then each process desiring to access the segment must attach the segment.
When finished with the segment, each process detaches the segment. At some point, one process must deallocate the segment. This is often referred to as Malloc. Finally the memory is organized into physical or logical memory. Logical memory is virtual memory. Mac OS X is unique in that the virtual memory is always on as opposed to Linux and Windows in which the virtual memory is created based on the size needed by the user. Also, OS X differs from Linux in that it does not use a preallocated disk partition for the backing store.
The backing store is the part of unused data that is stored on the disk as memory gets full. In contrast, Windows moves this same data to a paging file so it can be easily accessed. While memory management is a crucial part of any operating system, process management is a vital part of any system as well. Process Management Each operating system has a means to an end to execute processes, but each operating system handles these requests in their own fashion.
To best explain how each operating system handles process management, a few term are identified. A thread is the process of execution and a task is the unit of resource ownership.
Since Windows can run on many different platforms its native design is not complex. This allows the subsystems to mimic the structures of other processes. The process is started when a task is requested. The process is assigned a security access token, which Windows calls the primary token of the process. Along with the token, the process object are attributes, actions, or other services needed to complete the task. The last part of the process in Windows is the thread. The thread is what the operating system is executing as part of process execution.
They can be paused and resumed for the operating system to handle all requests efficiently. In a Linux operating system, tasks are handled in a data structure. Each task contains information is various categories including state, scheduling information, identifiers, links, times and timers, file system, address space, and processor-specific context.
Those categories can be described as attributes for the process. Each task also contains the execution state, which can be running, interruptible, uninterruptible, stopped, zombie.

Linux takes the user level threads for the tasks and can map them to kernel level processes with the same group ID. This provides resources sharing and security. Mac operating systems handle the execution of processes even differently than Windows and Linux. Mac has Grand Central Dispatch, which contains a pool of available threads.
Programs are designed to create blocks, which contain data and code on how to run. The scheduling of these blocks is setup in queues and can run in concurrency using first-in-first-out processing.
