Role of the Memory management unit in Operating system Every program for its execution requires some space in computer memory which is provided by memory management unit using virtual memory that provides the external storage addressing location for the programs that does not have too much space in main memory for their execution and saved them in secondary memory but when required loaded them again in main memory. This deallocation and reallocation of programs in main memory deals with concurrency. At last, we say that loading capabilities of programs with the memory addressing is there in it.

What is the Difference between memory management ans device management?
Memory Management.The kernel of a computer will have full access to the system's memory and is required to allow any processes to access this memory when needed. To do this, the kernel carries out virtual addressing. Within virtual addressing it is possible to make a given physical address to appear as a virtual address, i.e. Another address. These virtual address spaces are different for different processes.The memory that is processed to access one virtual address may be different to the memory that a process accesses at the same address. These spaces allow ever program on the computer to run as if it is the only one and stops these applications from crashing each other. Virtual addressing can also be used to create virtual partitions of memory in disjointed areas. One of these areas will be reserved for the kernel and other for applications.Device Management.Device drivers, processed by the kernel, are used in order to control the peripherals that are connected to the computer. These peripherals need to be accessed by processes to perform useful functions. A list of the available devices is maintained by a kernel and is either known in advance, configured by the user or detected by the operating system at run time.Device management is a very operating system specific topic and each of the drivers is handled differently by the different kinds of kernel design. The thing that they all have in common is that the kernel is required to provide the input output to allow drivers to access their devices.These two different facilities within the kernel of a computer are used alongside process management and system calls to help the kernel carry out its role within the system.

What is RAM Memory on a computer and what is it used for?
RAM is the Random Access Memory. The most primary role of RAM is to copy the operating system in to itself and then load the Operating System so that you can work. Also when you install any software, it requires some minimum amount of memory, else it will deny to install.For DOS, 16 MB of RAM is sufficientFor Windows 98, Minimum RAM requirement is 32 MBFor Windows XP, Minimum RAM requirement is 64 MBFor Windows Vista, Minimum RAM requirement is 512 MB
