1.through satellite assembly we can develop assembly and 
(if we want to use in any language like chines,etc and we 
can use it anywhere}


2. garbage collector run after a particuler point of time 
may depends on memory requiremtnt or time
first garbage collector check unused resources from memory
from generation first(which is L2 cache)and then find any 
references in genertion second(RAM)and then in third 
generation (virtual memory)

when garbage collector find any unused resources, it put 
that object in finalizition quere, for destruction of 
object and free memory from unused resources

and there is a thread is associated with which free objects 
one by one from this queue

and we can call  explicitly  the GC
like GC.collect(int )(here int is the generation number)
