by making is better in memory managment
Virtual memory management assist in the process of multitasking by providing extra memory when a computer has used up all its RAM. Virtual memory is however slower than RAM.
Cloud computing management usually comes in the form of a software suite that can manage one or more cloud computing platforms. Vendors like Microsoft, IBM, BMC Software and CA Technologies compete to provide the tools needed to create and administer virtual machines that support cloud technologies. These management packages tie multiple physical servers together to form a cloud that can then share CPU power, memory and storage with multiple virtual platforms.
Without virtual memory some computer programs wont be able to run. As the memory increases the computer may slow down its processes.
The memory management subsystem is one of the most important parts of the operating system. Since the early days of computing, there has been a need for more memory than exists physically in a system. Strategies have been developed to overcome this limitation and the most successful of these is virtual memory. Virtual memory makes the system appear to have more memory than it actually has by sharing it between competing processes as they need it.(by Mr. vicky lambole, Nandurbar)
Computers operate best when they have "system memory" free and are not relying on virtual memory (which uses a hard drive as additional system memory). If you have a system with 1GB of installed system memory, and you are using 1.25GB of allocated memory, then freeing up 0.25GB of used system memory would improve performance by reducing virtual memory usage. Conversely, if you have 2.0GB of installed memory, and you are using 1.25GB of allocated memory, then freeing 0.25GB of used memory would have no appreciable effect since virtual memory is not being used by the system. Final answer: If you are using virtual memory, then freeing enough memory to eliminate the virtual memory usage will improve performance, but freeing up more than that amount will have no appreciable effect.
MMU-memory management unit
it's the page that has been modified in main memory(physical memory), but not yet rewritten in the disk.
Find a virtual psychic to read your virtual memory.
virtual memory works just like as temporary memory does
The difference between virtual and physical memory is that virtual memory refers to memory space while physical memory are chips like RAM. The memory space for virtual memory is made by operating system when there is insufficient physical memory.
Segmented page allocation is a type of memory management that uses base and bound registers to determine memory faults, similar to dynamic page allocation. More importantly it is different to dynamic page allocation since the entire process doesn't have to be in memory, similar to using virtual memory paging where the program is broken into pieces. Unlike virtual memory paging, the maximum virtual memory size is limited to the size of physical memory.
Virtual memory, the answer is virtual memory.
