What is virtual memory?
Virtual memory is found on all computer operating systems and provides very practical advantages to PC users. All computer systems have their own RAM (physical random access memory), which usually ranges from 64 to 256 megabytes. If virtual memory is used, the system allows users to continue working without worrying about the availability of data storage or saturation of memory. It is often designed as a logical memory and allows users to access a larger volume of memory, allowing them to use multiple applications at the same time.
With virtual memory, the system is able to search for RAM applications that are not used, and the hard disk is the same. As a result, more space is released on RAM and new applications can be loaded that must be used immediately. The whole process is done automatically and the user does not have to click on anything. It works by distributing the address space of application programs into many smaller pages. Thamed Site ESE are 4K bytes of which each has a differentÉ virtual memory addresses.
Paging is a process that is virtual aspects of the sleeping (not if they are used) stored on the hard disk and after the user needs, they are restored to the actual memory. Page tables use computer operating systems to temporarily save this swap between virtual addresses of different applications and physical addresses (RAM). This part of the hard disk on which the site is temporarily stored is called the page file.
The ability to store these temporary addresses on the hard disk does not depend on RAM restrictions. There is also an automated calculation of the available page file. Thus, systems that have smaller rams would have to have larger pages. As a result, it is necessary to ensure that the size of the Page Page File is set to the maximum possible value.
Each operating system has its own coating supervisor for managing pages tables. INEditing pages are very effective in searching for files in physical memory that are least used and can be used to replace virtual memory files. However, there are some sites that cannot be replaced and are called non -classified or resident pages.
A computer system using virtual memory has access to a more economical way to create more storage space. Space with a hard disk is much cheaper than RAM chips that are installed on a PC. Using virtual memory, you avoid the need to upgrade/add RAM.
