Concept Of Virtual Memory. This technique virtualizes a computer architecture's various hardware memory devices (such as ram modules and disk storage drives), allowing a program to be designed as though: Virtual memory is used to give programmers the illusion that they have a very large memory even though the computer has a small main memory.

In computing, virtual memory, or virtual storage is a memory management technique that provides an idealized abstraction of the storage resources that are actually available on a given machine which creates the illusion to users of a very large (main) memory. Here, we take windows xp for example to show how to set the virtual memory. It is very helpful in implementing a multiprogramming environment.

Java Memory Model Interview Questions. Java memory model defines the legal interaction of threads with the memory in a real computer system. Java memory management mechanism garbage collects objects which are no longer referenced a true.

Utilize the connectionfactory object to establish the jms connection. When a thread invokes a method, the jvm pushes a new frame onto that thread's java stack. You should read difference between stack and heap memory.
