When an ASP.NET page is requested to a browser, ASP.NET creates an instance of a class that represents your page. That class is composed not only of the code that you wrote for the page, but also code that is generated by ASP.NET.This topic provides an overview of the code that is generated by ASP.NET. Generating and  running the page class code:- ASP.NET page runs as a unit, combining the server-side elements in a page, such as controls, with the event-handling code you have written. If you use a Web site project, you do not have to precompile pages into assemblies. ASP.NET dynamically compiles pages and runs them the first time they are requested by a user. If there are any changes to the page or resources the page depends on, the page is automatically recompiled. Web site projects also support precompilation of a Web project to enhance performance (for the first time a page request is received) and perform error checking as well as to support site deployment. ASP.NET W

When we declare a variable in a .Net application, it allocates some chunk of memory in to the RAM.  This memory has 3 things first the name of the variable, second data type of the variable and finally the value of the variable.  Now simple explanation of what happens in the memory, but depending on what kind of data type your variable is allocated on that type of memory. There are two types of memory allocation stack memory and heap memory.

When we move a value type to reference type the data is moved from the stack to the heap . When we move reference type to a value type the data is moved from the heap to the stack . This movement of data from the heap to stack and vice-versa creates a performance hit.

First we understand the differences b/w Multitasking Multiprocessing and Multi-Threading. Multitasking :  An Operating system provides to perform multiple task to user at a time that is called multitasking. For e.g . you sing song on VLC player while working on MS office. These are two types concept in Multitasking 1.    Multi-Processing 2.    Multi-Threading Multiprocessing : Computer system's ability to support more than one process or program at the same time. Multiprocessing operating systems enable several programs to run concurrently. UNIX is one of them. Multiprocessing systems are much more complicated than single-process systems because the operating system must allocate resources to competing processes in a reasonable manner. It refers to the utilization of multiple CPU's in a single computer system. This is also called parallel processing.

Asp.Net provide platform for building Web applications. When a page is requested, it is loaded into the server memory, processed and sent to the browser. Then it is unloaded from the memory. At each of this steps, methods and events are available, which could be overridden according to the need of the application. The phases of page life cycle are: 1.    Page Initialization        a.    Page_PreInit        b.    Page_Init        c.    Page_InitComplete 2.    Page Load (load all control Button,TextBox)       a.    Page_PreLoad       b.    Page_Load       c.    Page_LoadComplete 3.    Page Render        a.    Page_Prerender        b.    Page_PreRenderComplete        c.    Page_SaveStateComplete

Overview - Sensor ? A sensor is a converter that measures a physical quantity and converts it into a signal which can be read by an observer or by an instrument . Processing such a signal reveals some properties about objects located and/or event happening in the vicinity of the sensor. A large number of these disposable sensors can be networked in many applications that require unattended operations. Sensor node ? A sensor node, also known as sensor pod or a mote, is a component of a wireless sensor network. Each node in the network is responsible for collecting data about the environment around it and sending that data to processors in the network. A mote is node but a node is not always a mote. Fig 1: The typical architecture of the sensor node. Components - The main components of a sensor node are a micro-controller , transceiver , external memory , power source and one or more sensors .

The term Artificial Intelligence ( AI ) was coined by John McCarthy in 1955, defined it as "the science and engineering of making intelligent machines". The various definitions have been proposed since then by scientist and researchers. It is the science and engineering of making intelligent machines, especially intelligent computer programs. It is related to the similar task of using computers to understand human intelligence, but AI does not have to confine itself to methods that are biologically observable. [ John McCarthy ] The goal of work in artificial intelligence is to build machines that perform tasks normally requiring human intelligence. [ Nilsson. Nils J. ]

Ring Topology - A ring network is network topology in which each node connects to exactly two other nodes, forming a single continuous pathway for signals through each node - a ring. Data travel from node to node, with each node along the way handling every packet. Because a ring topology provides only one pathway between any two nodes, ring networks may be disrupted by the failure of a single link. A node failure of cable break might isolate every node attached to the ring. In response, some ring networks add a "counter-rotating ring" (C-Ring) to form a redundant topology: in the event of a break, data are wrapped back onto the complementary ring before reaching the end of the cable, maintaining a path to every node along the resulting C-Ring. Such "dual ring" network include Spatial Reuse Protocol, Fiber Distributed Data Interface (FDDI), and Resilient Packet Ring. 802.5 network - also known as IBM token ring network - avoid the weakness of a ring t

 Introduction to Prolog Programming The Basics Prolog (Programming in logic) is one of the most widely used programming languages in artificial intelligence research. As opposed to imperative languages such as C or java (the latter of which also happens to be object-oriented) it is a declarative programming language. That means, when implementing the solution to a problem, instead of specifying how to achieve a certain goal in a certain situation, we specify what is situation (rules and facts) and the goals (query) are and let the prolog interpreter derive the solution for us. Prolog is very useful in some problem areas, such as artificial intelligence, natural language processing, database,.... but pretty useless in others, such as graphics or numerical algorithms. Basic Features of Prolog Features of Prolog are:- Facts Terms Queries Logical Variables Shared Variables Data Types in Prolog Rules
