There is no one right answer to this question. Basically, it depends on the Operating System (OS) that is running on the computer. Every OS has minimum system hardware requirements, which include memory, processor, disk space, etc. If those minimum system hardware requirements are met, and the OS supports the running of multiple applications at the same time, it should work. Performance, however, will vary according to the system hardware.

Also note that performance depends on the type of applications and the demand on those applications (design and virtual machine programs use much more). In some environments a computer user may open 10-20 different applications (or subsequent sub apps) in which not even a modestly performing computer system can handle. If the physical memory on the system is exceeded there is also paged/virtual memory which is cached on the hard drive temporarily. Almost all operating systems and applications will state their memory requirements, so taking those requirements into account can give you a general idea of the amount of memory you will need.

How do you lower physical memory usage?

You can lower the physical memory (RAM) usage by running less applications as much as you can. Stop the applications from running in windows start up. Close the applications and services which you are not using. Increase the virtual memory of the system as it will act same as physical RAM. Here are few steps to stop the applications running at start up: - Go to Run and type in msconfig - Go to the Services tab and uncheck all services that you know you don't need (becareful dont uncheck the services you are not familiar with) - Go to the Startup tab and uncheck any startup items you don't need. - Hit OK and reboot.

Most modern computers use Random Access Memory for their main memory.
