yes. i have thanks you to your answer. 
but, i can not understand about memory management . 
in your messages,

************************************ 
 The processes compete for available memory. There are usage statistics
gathered , that help make an estimation of the probability of 
future use. 
************************************

but , I can not understand what is usage statistics gathered. 
and what is "make an estimation of the probability of future use" 
in first , in system booting, in startup,
the what is usage statistics , 
and what is probability, 
i known that frame allocation size is static, 
but if in previous test, more page fault is occur, 
next frame allocation size about same process is increase. 

but I don't know how many memory size is allocated in first. 
if gathered data is not, how mwny memory size is allocated, 
I know correct usage statistics   and probability.
