This is why you should add as much RAM to your PC as possible; the more memory that you add, the less likely that Windows needs to resort to virtual memory. Information about the device's operating system, Information about other identifiers assigned to the device, The IP address from which the device accesses a client's website or mobile application, Information about the user's activity on that device, including web pages and mobile apps visited or used, Information about the geographic location of the device when it accesses a website or mobile application. And yes, if you’re wondering, all that activity shortens the life of your hard drive over time. Virtual memory is a section of volatile memory created temporarily on the storage drive. It uses a portion of the empty space on your hard drive to temporarily hold the data that would otherwise be held in your computer’s memory. Modern operating systems (Windows 8/7/Vista/XP, Mac OS X, Unix, and Linux) all use the virtual memory trick to feed your applications the memory they need. Programs use virtual addresses to store instructions and data; when a program is executed, the virtual addresses are converted into actual memory addresses. Mark has written a variety of books including Build Your Own PC Do-It-Yourself For Dummies. When you run out of physical memory, the hard drive activity light on the front of your machine never seems to go out. If Windows were limited to using only your computer’s physical RAM (the memory modules you installed on your PC’s motherboard), you would be up a creek because Windows 8 requires a minimum of around 500MB of memory itself, and Photoshop takes a significant chunk of memory to run. This frees up space in RAM to load the new application. Let’s say that an OS needs 120 MB of memory in order to hold all the running programs. In this case, your hardworking silicon warrior uses 2GB of hard drive space, so the total memory available within Windows (using both 2GB of physical memory and 2GB of virtual memory) is now 4GB, providing more elbowroom to work with. How much is enough? Also, note that virtual memory is always slower than true physical memory. Virtual memory, as its name suggests, doesn’t physically exist on a memory chip. And, don’t forget that you’d probably be running more than one application at a time. Weird & Wacky, Copyright © 2020 HowStuffWorks, a division of InfoSpace Holdings, LLC, a System1 Company. Your programs don’t know that they’re using virtual memory — Windows takes care of everything behind the scenes, so Photoshop thinks that you have 4GB of physical memory. It uses software to consume more memory by using the HDD as temporary storage while MMUs translate virtual memory addresses to physical addresses via the CPU.

Specifically, the system can operate as if its total RAM resources were equal to the amount of physical RAM, plus the amount of virtual RAM. With virtual memory, what the computer can do is look at RAM for areas that have not been used recently and copy them onto the hard disk. Why has Germany blocked sales of the Samsung Galaxy Tab? Among the primary benefits of virtual memory is its ability to handle twice as many addresses as main memory. Virtual memory enables a system to run larger applications or run more applications at the same time without running out of RAM. How Virtual Memory Works on Your PC By Mark L. Chambers Pseudo-RAM called virtual memory actually exists on your hard drive rather than as memory modules on your motherboard.
