Memory is an internal storage device which stores all-important information of your computer. It defines as data storage in form of chip. The term storage is mainly used for the memory which you can find in disks and tapes. It is a physical memory that holds the data and there are virtual memories as well which enlarges to physical memory in hard disk of computer. All computers come with specific size of physical memory which is known as RAM (Random Access Memory) or actual memory. Each computer memory holds the information that comes with an array of various boxes. A memory of 1 MB can hold information around 1 million bytes.
Have you ever come across a situation when you were running a few programs on your PC and facing slowness issue? The most likely answer of many people would be ‘Yes’. During that time, you can get a message like “Your computer is low with virtual memory” or receive any other pop up. Now, you may be thinking: What is virtual memory? Why you need to increase virtual memory? How you can increase it? In this article, you can clear your doubts about virtual memory.
Let’s first read the brief details about virtual memory. Your PC has a hard drive which stores all data (documents, pictures, spreadsheets, presentations, music files, software applications etc.) on permanent or temporary basis. When you open any application, it first gets loaded to RAM so that it can be executed.
Once you close the application, it automatically removes from RAM. Therefore, the more the size of your RAM, the more storage space it has to store more applications. However, if the size of RAM is not sufficient to execute any application, it may make your PC very slow. In this situation, you need to add some extra memory to your computer. This upgrading computer memory is called as virtual memory.
Steps to increase the virtual memory can differ as per your operating system such as Windows XP, Windows Vista, Windows 7, MAC etc. You need to first check out the correct steps by your operating system and then follow them one after other. You can take help from manufacturer’s website to check these guidelines.
The virtual memory can be either segmentation or paging. Most of the computers practice page tables and they translate all the virtual addresses of application programs to physical addresses that are used by processor to follow the guidelines. It maintains the complete mapping of virtual addresses and physical addresses.
