Virtual memory is a crucial feature of modern operating systems that enables applications to utilize memory addresses that exceed the available physical memory (RAM). By using a combination of hardware and software, virtual memory creates an abstraction of a larger memory space, allowing applications to operate as though they have access to a much larger addressable memory. This is achieved through a technique called paging, where portions of memory (pages) can be loaded into physical memory from secondary storage (like a hard drive) as needed. Virtual memory enhances system performance and provides an effective way to manage memory, allowing multiple applications to run concurrently without being constrained by physical memory limitations. It also isolates the memory of different applications, enhancing security and stability within the operating system by preventing one application from accessing the memory space of another. Option A (Increase physical memory) - Virtual memory does not increase the physical memory available; it allows better utilization of existing physical memory and the use of disk space. Option C (Improve speed of memory access) - While virtual memory allows for more efficient memory management, it may introduce overhead due to paging, which can slow down memory access compared to direct physical memory access. Option D (Manage disk space) - Virtual memory primarily focuses on managing memory addresses rather than directly managing disk space for applications. Option E (Backup for physical memory) - Virtual memory is not a backup mechanism but rather a way to extend the usable memory space by utilizing disk storage.
