I was wondering why when I run task manager > performance - it gives me the amount of memory available (e.g. 2000MB), when I run a program, (say Firefox) it drops to a smaller amount of memory that is calculated as being available (e.g. it will drop to 1950MB).
My question is why doesn't it go back to 2000MB when I close Firefox, for example, it will go to 2010 or something.
Thanks in advance.
