Try increasing your paging file. There are very clear and detailed instructions in the link below.
The RAM (random access memory) usually stores temporary files and cache to help speed up your computer by not having to repeatedly load the same thing but is you do not restart your computer the RAM will become full and it will slow down your computer so every now and then just restart the computer for best performance.
Rom
In computing, memoryrefers to the physical devices used to store programs (sequences of instructions) or data (e.g. program state information) on a temporary or permanent basis for use in a computer or other digital electronic device.
Internal memory (RAM)
Virtual memory is hardware that the computer uses to load the operating system and run all of the programs. It is stated that the more memory that the computer has, the faster the programs will run.
The Ram - Random Access Memory temporarily holds programs and data while the computer is on and allows the computer to access that information randomly.
the most common computer memory which can be used by programs to perform necessary tasks while the computer is on; an integrated circuit memory chip allows information to be stored or accessed in any order and all storage locations are equally accessible.
two types of memory i.e. primary and secondary memory.
Without virtual memory some computer programs wont be able to run. As the memory increases the computer may slow down its processes.
ROM (Read Only Memory) stores the information currently being used by the computer. It holds all your loaded programs, and the data that goes along with them, waiting for the processor to make use of the information (to process it, if you will). RAM (Random Access Memory) is memory which cannot be changed. This would be information hard-wired into your electronic device. For a computer, this might be the default BIOS and BIOS settings.
Memory is a loose term when it comes to computers. Memory can mean one of two things that are both primary and absolutely necessary to run a computer. One is RAM, which is the smaller memory that helps with computer performance. Without it, the computer will not start up at all because the RAM is used for essential backround tasks. The other memory is HDD memory (hard drives). This memory is used to store information that does not need to be accessed instantaneously. HDD memory is used to store the operating system of a computer, as well as other information such as programs and documents. There is no "primary" memory, in a computer, as it can mean two different things that are both invaluable.
The computer's Random Access Memory (RAM) temporarily stores data and programs while your computer is on.
