3) New: wen tester reports a defect
Open: wen developer accepts that it is a bug or if the 
developer rejects the defect, then the status is turned 
into "Rejected"
Fixed: wen developer make changes to the code to rectify 
the bug..
Closed/Reopen: wen tester tests it again. if the expected 
result shown up, it is turned into "Closed" and if the 
problem ersists again, its "Reopen"

4) Defered status means the developer accepted the bus, but 
it is scheduled to rectify in the next build.

5) Testing the application whether its performing its basic 
functionality properly or not, so that the test team can go 
ahead with the application

6) Definitely can use.

7) Verification is static. no code is executed. say, 
analysis of requirements etc.
Validation is dynamic. code is executed with scenarios 
present in test cases.

8) varies from company to company.

9) varies from company to company (refer to symphony and 
mphasys websites for differant methodologies)

10) report it in bug tracking tool.

11) Its your project. you should know it.

12) Test plan is a document which contains the scope for 
testing the application and what to be tested, when to be 
tested and who to test.

13) Time, resource and Money

14) V model, Waterfall model etc..

15) AdHoc means doing something which is not planned.

16) Its a document released along with the product which 
explains about the product. it also contains about the bugs 
that are in defered status.

19) It varies with the complexity of requirements. Some 
write 1 or 2/day. Some write upto 20/day

20) The interviewer was asking about Bug tracking tool that 
you use..

Friends, plz correct me if i am wrong at any part...

For the questions from 3 to 20 answers ahve given by Naresh.
I dont want to make comments on this further.

Here I am givign the answers for 1 and 2.

1)Diff. between Application server and web server?
A Web server serves pages for viewing in a Web browser, 
while an application server provides methods that client 
applications can call.A Web server exclusively handles HTTP 
requests, whereas an application server serves business 
logic to application programs through any number of 
protocols.

The Web server
A Web server handles the HTTP protocol. When the Web server 
receives an HTTP request, it responds with an HTTP 
response, such as sending back an HTML page. To process a 
request, a Web server may respond with a static HTML page 
or image, or delegate the dynamic response generation to 
some other program such as CGI scripts, JSPs (JavaServer 
Pages), servlets, ASPs (Active Server Pages), server-side 
JavaScripts, or some other server-side technology. Whatever 
their purpose, such server-side programs generate a 
response, most often in HTML, for viewing in a Web 
browser.The Web server doesn't provide any functionality 
beyond 
simply providing an environment in which the server-side 
program can execute and pass back the generated responses. 
The server-side program usually provides for itself such 
functions as transaction processing, database connectivity, 
and messaging.While a Web server may not itself support 
transactions or database connection pooling, it may employ 
various strategies for fault tolerance and scalability such 
as load balancing, caching, and clustering.

The application server
An application server exposes business logic to client 
applications through various protocols, possibly including 
HTTP. While a Web server mainly deals with sending HTML for 
display in a Web browser, an application server provides 
access to business logic for use by client application 
programs. The application program can use this logic just 
as it would call a method on an object.
The information traveling back and forth between an 
application server and its client is not restricted to 
simple display markup. Instead, the information is program 
logic. Since the logic takes the form of data and method 
calls and not static HTML, the client can employ the 
exposed business logic however it wants.the application 
server manages its own resources. Such gate-keeping duties 
include security, transaction processing, resource pooling, 
and messaging. Like a Web server, an application server may 
also employ various scalability and fault-tolerance 
techniques.Additionally, most application servers also 
contain a Web server, meaning you can consider a Web server 
a subset of an application server. While application 
servers contain 
Web server functionality, developers rarely deploy 
application servers in that capacity. Instead, when needed, 
they often deploy standalone Web servers in tandem with 
application servers.


2)Default port number for Tomcat application server is 80.
  Defalt port number for Websphere application server is 
7001.

For 16th quesion answer is ,in our company relase notes 
document prepared by client himself.In this documetns,he 
mentions all the bugs which re diferred from from prious 
releases and the most important bugs logged  at the time of 
project deadlines.And also,he mentiones the workaround for 
every bug says how to overcome from the bug,while using the 
software.
