Q.7. Short answer questions.(2 Marks)
1.
What is a cookie?
Cookies
are usually small text files, given ID tags that are stored on your computer's
browser directory or program data subfolders. Cookies are created when you use
your browser to visit a website that uses cookies to keep track of your
movements within the site, help you resume where you left off, remember your
registered login, theme selection, preferences, and other customization
functions. The website stores a corresponding file(with same ID tag)to the one
they set in your browser and in this file they can track and keep information
on your movements within the site and any information you may have voluntarily
given while visiting the website, such as email address.
2. What is session? Give use of session
state?
A Session object stores information about,
or change settings for a user session. When you are working with an application on your computer, you open it,
do some changes and then you close it. This is much like a Session. The computer
knows who you are. It knows when you open the application and when you close
it. However, on the internet there is one problem: the web server does not know
who you are and what you do, because the HTTP address doesn't maintain
state.ASP solves this problem by creating a unique cookie for each user. The
cookie is sent to the user's computer and it contains information that
identifies the user. This interface is called the Session object.The Session
object stores information about, or change settings for a user session.
3. Explain application state.
Application
state is a data repository available to all classes in an ASP.NET
Application. Application state is stored in memory on the server
and is faster than storing and retrieving information in a database. Unlike
session state, which is specific to a single user session, application state
applies to all users and sessions. Therefore, application state is a useful
place to store small amounts of often-used data that does not change from one
user to another. For information on saving data on a per-user basis see Session State
Overview and ASP.NET Profile
Properties Overview.
4. Give an explanation of any four server
variables.
AUTH_PASSWORD
|
Returns the value entered in the client's authentication dialog
|
AUTH_TYPE
|
The authentication method that the server uses to validate users
|
AUTH_USER
|
Returns the raw authenticated user name
|
CERT_COOKIE
|
Returns the unique ID for client certificate as a string

Definition
-
1) CLS-(Common
Language Specification )
The Common Language Specification is set of
language features that.Net Languages need to develop Applications and services
which are supported by the Common Language Runtime (CLR).
2) FCL(Framework
Class Library)-
The .NET Framework has large groups of
predefined classes, known as the .NET Framework Class Library. (FCL)
3) CLR-
(Common Language Runtime)
The .NET framework provides a run-time
environment called the Common Language Runtime which runs the code and provides
services that make the development process faster.

cross-language interoperability, managed execution, application domains, and
assemblies.

.Net
Framework Architecture Diagram
Advantages of ASP.Net-
1. ASP.NET
drastically reduces the amount of code required to build large applications.
2. With
built-in Windows authentication and per-application configuration, your applications
are safe and secured.
3. It
provides better performance by taking advantage of early binding, just-in-time
compilation, native optimization, and caching services right out of the box.
4. The
ASP.NET framework is complemented by a rich toolbox and designer in the Visual
Studio integrated development environment. WYSIWYG editing, drag-and-drop
server controls, and automatic deployment are just a few of the features this
powerful tool provides.
5. Provides
simplicity as ASP.NET makes it easy to perform common tasks, from simple form
submission and client authentication to deployment and site configuration.
6. The source
code and HTML are together therefore ASP.NET pages are easy to maintain and
write. Also the source code is executed on the server. This provides a lot of
power and flexibility to the web pages.
7. All the
processes are closely monitored and managed by the ASP.NET runtime, so that if
process is dead, a new process can be created in its place, which helps keep
your application constantly available to handle requests.
8. It is
purely server-side technology so, ASP.NET code executes on the server before it
is sent to the browser.
9. Being
language-independent, it allows you to choose the language that best applies to
your application or partition your application across many languages.
10. ASP.NET
makes for easy deployment. There is no need to register components because the
configuration information is built-in.
11. The Web
server continuously monitors the pages, components and applications running on
it. If it notices any memory leaks, infinite loops, other illegal activities,
it immediately destroys those activities and restarts itself.
12. Easily
works with ADO.NET using data-binding and page formatting features. It is an
application which runs faster and counters large volumes of users without
having performance problems.
ASP.NET
Coding techniques Single File and Code Behind
Code Behind
|
Single File
|
The HTML and controls are in the .aspx file, and the
code is in a separate .aspx.vb or .aspx.cs file.
|
The code is in <script> blocks in the same.aspx file that contains the HTML
and controls.
|
The code for the page is compiled into a separate class from which
the .aspx file derives.
|
The .aspx file derives from the Page class.
|
All project class files (without the .aspx file
itself) are compiled into a .dll file, which is deployed to
the server without any source code. When a request for the page is received,
then an instance of the project .dll file is created and
executed.
|
When the page is deployed, the source code is deployed along with the
Web Forms page, because it is physically in the .aspx file.
However, you do not see the code, only the results are rendered when the page
runs.
