open file...!!! what happens when you just give this command..!!

-
Before staring this article i would like to clear about what is RAM ....?

So RAM is the memory with which we usually work in computer that is whatever is visible in our computer screen say if we opened a word document than that is visible to us and can change the data in it by modifiying the previous data or by writing the new document .

The meaning of above sentence is simple that whatever we see in monitor or display device is RAM .

SO NOW moving on  suppose you wrote something  in word now suddenly if light goes off then ..??? surely our data that we wrote will not be present and when  light comes , we switch on the computer we see that the data is destroyed..!!  so  this is the first charecteristic of RAM that is RAM is volatile (to vapuour up) now second thing happens is by mistake we closed our document then also same thing happens the data gets perished away....!!

Now we want that our data might be safe and must be present whenever we want then...??

yess the result is save so what is save command ...??

Usually we ask people that give the defination of save and they are like dumb humans save ....!!! save means simply save nothing else but according to me Save has a defination save means to store something by giving a name that means to store our data by giving a name that is the similar defination of file what is file collection of data by having name ...!!

So NOW the meaning of RAM is clear to all whatever is visible to us on the monitor screen for any purpose reading or writing is the data in the RAM this is the defination i have derived .

 When we store the data the data is in disk that is on the permanent memory after we store the file the file is not visible to us after we shut down and again we open the computer we need that file so we go to file menu and select the name to get that file and give "open" command than what is the actual mechanism behind it..?? what happens by clicking "open" we give a command to ROM to fetch data from disk and load into RAM and again as i said whatever is visible  is in the RAM so that data is now in RAM again you press "save" button than what happens actually you give the opposite command to ROM to transfer the data from RAM to disk that is permanent memory .


THIS WAS SOMETHING DIFFERENT FROM C , CPP, JAVA 
BUT ITS QUITE AN INTERESTING ONE.....!!

State space search / blocks world problem by heuristic approach /TIC TAC TOE

-
A lot of AI is about SEARCH. The "state space" is the set of states of the problem we can get to by applying operators to a state of the problem to get a new state. A  state  contains  all of the information necessary to predict the effects of an action and to determine if it is a goal state. State-space searching assumes that the agent has perfect knowledge of the state space and can observe what state it is in (i.e., there is full observability); the agent has a set of actions that have known deterministic effects;some states are goal states, the agent wants to reach one of these goal states, and the agent can recognize a goal state. a solution is a sequence of actions that will get the agent from its current state to a goal state. Define the Problem as State Space Search Consider the problem of “Playing Chess” . to build a program that could play chess, we have to specify the starting position of the chess board, the rules that define legal moves. And the

Navigation in Vaadin.

-
Plain Vaadin applications do not have normal web page navigation as they usually run on a single page, as all Ajax applications do. Quite commonly, however, applications have different views between which the user should be able to navigate. The  Navigator  in Vaadin can be used for most cases of navigation. Views managed by the navigator automatically get a distinct URI fragment, which can be used to be able to bookmark the views and their states and to go back and forward in the browser history. The  Navigator  class manages a collection of  views  that implement the  View  interface. SO the class in which you are defining Navigation must implement with a  View  interface. addView() i s the method by which you can register Your View . You can add your view at any point ,Your View must have   name identifier and be added to a  View . Once registered, you can navigate to them with  navigateTo() . Navigator  manages navigation in a component container, which can be
