1. Explain what is port? what is HTTP port, FTP port, Telnet port and others?

ports are like different gates of the building. Each gate is having its own function.

HTTP Port .... it will allow only HTTP people... It communicates in HTTP protocol.. any request with http:// .... HTTP.. is Hyper Text Transfer Protocol

FTP Port : File Transfer Protocol.... used to upload and download files..... used to update websites from the local machine... it requires FTP host name, username and password.. and on the host machine FTP services should be enabled.

Telnet port: telenetting with other computer in hybrid environment... from thin client to server..

2. Explain how Search engines work?

8. Explain in type2 dimension/flag current mapping there are three data flows i.e
1. data flow for new rows
2 .data flow for changed row
3. data flow for updated changed row
whats the difference between last two data flow?

When we are working with FLAG we can use only 2 filter transformations
also but at the initial stage it will be better to go with 3 filters. Where we
are using the FIRST Filter to insert the records for first
time, In second Filter we are inserting the records but these records are with
updated information and in third filter we are updating the records with
surrogate key. This third filter records will be updated with our changed
FLAG value 'ZERO'. Because we are identifying the current records with FLAG
values 'ONE'.

9. Explain the term "non volatile memory" states?

1. that memory is retained in the memory unit for some time even
after power failure to the memory unit
2. that memory is lost by power failure but regained as soon as
power is restored
3. that memory is retained in the memory unit at higher temperature
4. that memory is retained in the memory unit for years after power
failure to the memory unit

10. What is the main difference between portability and Platform independent?

I agree it is correct to say that Java is platform independent, but it is due to the Java Virtual Machine. Java programs are only intermediately compiled, which allows adaptation to the given environment it needs to run in later.

An example of a portability issue is the creation of Unix. The first version was not portable. It was specific only to that computer's architecture. Unix became portable when it was rewritten in C. The new version written in C was portable because C served as a "translator", if you will, between what underlying architecture or devices were physically in the computer and what unix wanted them to do.

12. Explain how do we solve conflict scenario with business clients? explain?

I would like to slightly repharce this quesion as, How can we handle indifference of opinion in the requirements?

Usually when we interact with the client as a representative of our organnization, one important this we need to follow is setting the right expectation even before we start gathering the requirements. When i say setting the right expectations, it means, making the client aware of your organizatations resource availability, technology areas, domain expertise, able to handle changes,etc.

And as the saying goes, "Talk to Resolve" most of the clients are open to discssion in the current industry trend, so sit and negotiate with your client and make him understand your organization capabilites.

The other way of resolving confilt is, implementing a strong change management process with in the software development life cycle.

1. Intereviewing Techniques.
2. Case Study methods.
3. Joint Application Development Method.
4. Application Explorer method.
5. Brain Stroming approach,etc.

There are also different tools used for requirement gathering like, UML, Rational Rose, Microsoft Visio, Recruitment Matrix,etc.

14. Suppose if GET method is less secure than POST method then why they introduced GET method.and well use only POST method alone. Wats the need for GET here?

Using GET method form data is appended to URL while using POST method it is transferred in the message body.
GET method is intended for information retrieval. It should be used to retrieve information that do not change state of server.
For functions such as login, POST method is preferable due to security reasons.

virtual functions are the functions by which we can implement the concept of polymorphism ,ie one name with several distinct forms.a f'n preceded by a virtual keyword makes a function virtual means the compiler turns on the mechanism to perform late binding or dynamic binding.more of all,the same function name can be used to perform different tasks .

44. Tell me what is the difference between connecting to RDBMS using ODBC and native drivers?

ODBC is an open standard for software providers to follow when creating an intermidate layer between the database and the application using the database. Having "open standards" usually means that different applications can write their code the same way no matter which database they are using, as long as that database comes with an ODBC driver.In contrast, native drivers are built with one specific database in mind. Thus, applications written to use the native driver will only work with one particular database. You will lose flexibility in your code's ability to switch database vendors, but you might gain performance enhancements due to the fact that the driver is custom made for the database and may be able to take advantage of an "insider's view" of the database software.

51. Define raster and vector data. Explain what is the difference between raster and vector data?

Raster data is a set of horizontal lines composed of individual pixels, used to form an image on a CRT or other screen.Raster data makes use of matrix of square areas to define where features are located. These squares are typically of uniform size, and their size determines the detail that can be maintained in the dataset.Raster data represent square areas, they describe interiors rather than boundaries. Vector data use X and Y coordinates to define the locations of points, lines, and areas (polygons) that correspond to map features, vector data tend to define centers and edges of features.They are excellent for capturing and storing spatial details

52. A Two-dimensional array X (7,9) is stored linearly column-wise in a computers memory. Each element requires 8 bytes for storage of the value. If the first byte address of X (1,1) is 3000, what would be the last byte address of X (2,3)?

64. A function is running, it has its own stack pointer, memory area now it invokes another function from this point what changes will be in its memory area and what other changes in data segment, stack segment, heap segment. I want a complete picture of memory architecture?

There will be a lot of changes in fact. First of all, all the variables the function was suing needs to be pushed into the stack. (we need all these variables when we return from the other function). The Program counter will be pushed to stack too... (When the "return" of second function occurs we should know where to 'return' to)These are the basics which are bound to happen when a function calls another.

The data container is nested in the List object that is created when you add a section.

4. Drag the data container to Page Body.

The data container appears as a node of Page Body.

5. Delete the List object.

In the Query Explorer, the query that is created when you add a section is also deleted.

6. From the View menu, click Page Design.

7. In the Insertable Objects pane, click the Query Items tab.

8. Drag the query item that was used as a section header back into the data container.

67. What is virtual Memory under Linux?

Linux supports virtual memory, that is, using a disk as an extension of RAM so that the effective size of usable memory grows correspondingly. The kernel will write the contents of a currently unused block of memory to the hard disk so that the memory can be used for another purpose. When the original contents are needed again, they are read back into memory. This is all made completely transparent to the user; programs running under Linux only see the larger amount of memory available and don't notice that parts of them reside on the disk from time to time. Of course, reading and writing the hard disk is slower (on the order of a thousand times slower) than using real memory, so the programs don't run as fast. The part of the hard disk that is used as virtual memory is called the swap space

68. Explain what are the differences between Desktop and Enterprise Application?

Desktop application runs on a single machine. It could be a part of network. But Application and database resides on same machine. And only one user can access it at a time.Enterprise application is generally a multi-tier application. Many a concurrent users can access data and application at a time.

72. Why dont we give a & before reading a string in C language?
scanf("%s",str); why is it not scanf("%s",&str);

We don't give an & before reading a string. This is so because a string is a character array. For an array, be it integer or character or any other array, declared as int a[10] or char str[20], the name 'a' or 'str' stores the base address of the array, that is the address of the memory location where the array is starting. The scanf statement requires the address of the location to store the value input by the user. Since str already stores the address of the memory location we do not need to add the & before it.

73. Give the complete difference between database, relational database and object database?

A database is an organized collection of information. It is structured so you can jump to the information by using a key, and find related infromation by navigating a path. A sequential (flat) file is not considered a database.

A relational database contains one-to-many relationships.

A networked database contains one-to-many and many-to-many relationships.

87. Explain CDROM access is random or semi random or sequential?

CDROM access is sequential..
Magnetic sequential access memory is typically used for secondary storage in general-purpose computers due to their higher density at lower cost compared to RAM, as well as resistance to wear and non-volatility. Examples of SAM devices still in use include hard disks, CD-ROMs and magnetic tapes. Historically, drum memory has also been used.

88. What are the advantages & disadvantages of vertical cluster & horizontal cluster? Which is the best? Why?

In horizontally clustered environment, cluster-enabled application is deployed on multiple physical machines. Each machine is available for requests. Horizontal clusters offers protection over hardware failure, increases efficiency, provides load balancing and process failover. However, since there are many number of physical machines involved the installation and maintenance cost increases proportionally.

In Vertical clustering, multiple application server instances are hosted on the same physical machine. This type of clustering provides increased efficiency, load balancing and process failover. However, if hardware fails then there may not be ready alternative.

91. Explain what is the difference between Process and thread with real time examples?

1.Threads share the address space of the process that created it; processes have their own address.

2.Threads have direct access to the data segment of its process; processes have their own copy of the data segment of the parent process.

3.Threads can directly communicate with other threads of its process; processes must use interprocess communication to communicate with sibling processes.

4.Threads have almost no overhead; processes have considerable overhead.

5.New threads are easily created; new processes require duplication of the parent process.

6.Threads can exercise considerable control over threads of the same process; processes can only exercise control over child processes.

7.Changes to the main thread (cancellation, priority change, etc.) may affect the behavior of the other threads of the process; changes to the parent process does not affect child processes.

92. Define ROM image and explain each section of a ROM image in an exemplary system?

A ROM image captures the data from a read-only memory chip, such as hardware firmware, video and arcade game boards, etc. It is often used for emulation.

Get address of next node
Delete first node
Do not to access next of the current node after deleting the current node.
Move next node to first node

If the list is empty, the head pointer will be NULL.

94. Explain how to calculate response time in Client-Server technology?

This can be done by measureing the time taken by the first byte to reach the client (TTFB) and the time taken by the last byte of the response to reach the client (TTLB) by using various network bandwidths between the client and the server.

95. Do you know hows do electrons travel through a lightning bolt?

Generally, lightning is negatively charged. During thunderstorms. The Earths is recharged and its surface becomes good conductor of electricity. The Earth is charged negatively and the atmosphere is charged positively. Electrons flow upwards from the entire surface of the Earth. Thunderstorms help transfer the negative charges back to Earth.

96. What is race around condition?

A race around condition is a fault in the process or a system where the output or the result of the process is critically and unexpectedly dependent on the timing of other events. Race condition especially occurs in multithreaded or in distributed systems.

97. Explain what are mutants and explain mutation testing?

A mutated program is called Mutant and Mutation testing is based up on seeding the Implementation with a Fault by applying mutation Operator and determining whether Testing Identify this fault is called Mutation testing

98. Tell me why constructors does not supports visual functions?

Constructor does not support virtual functions because we need an object to invoke a virtual method in the first place and more over constructors are used to initializing objects,which is a static type.Virtual functions are invoked on the dynamic type of the object,hence the object may not be properly initialized when a constructor call is made.Since the derived part of the object would not be initialized during the execution of base class constructor,hence calling any virtual method from base class constructor does not work well.

99. What is multithreading?

Multithreading is the ability of a program or an operating system process to manage its use by more than one user at a time and to even manage multiple requests by the same user without having to have multiple copies of the programming running in the computer. Central processing units have hardware support to efficiently execute multiple threads. These are distinguished from multiprocessing systems (such as multi-core systems) in that the threads have to share the resources of a single core: the computing units, the CPU caches and the translation lookaside buffer (TLB).
