Company:SATYAM
Date of the exam:02-02-2008
Pattern of the Exam:15 Questions in 30 minutes
G.D round( this is the most eleminating round)
Interview(both technical and HR Simultaneously)
750 ppl have attended the written test out of which 300 ppl were shortlisted in the exam.
then out of 300 only 120 ppl have been selected for the interview after the GD round.
then finally 58ppl have been selected for the company.
Marks:1 mark for correct answer and ¼ negative mark for every wrong answer.
The exam was not easy but can be attempted if we work hard and be confident.
Be cautious as there is negative marking and hence don’t take risk with bad gueses.
The questions that I am giving here r just the models.
The numbers are not the same but models r same.
So take care of the questions.
Prepare taking these models as examples but don’t depend on the numbers given here.

Question 1: How does the race condition occur? It occurs when two or more processes are reading or writing some shared data and the final result depends on who runs precisely when. Question 2: What is multiprogramming? Multiprogramming is a rapid switching of the CPU back and forth between processes. Question 3: Name the seven layers of the OSI Model and describe them briefly. Physical Layer - covers the physical interface between devices and the rules by which bits are passed from one to another. Data Link Layer - attempts o make the physical link reliable and provides the means to activate, maintain, and deactivate the link. Network Layer - provides for the transfer of information between end systems across some sort communications network. Transport Layer - provides a mechanism ...

What is JSP? Describe its concept. JSP is a technology that combines HTML/XML markup languages and elements of Java programming Language to return dynamic content to the Web client, It is normally used to handle Presentation logic of a web application, although it may have business logic.What are the lifecycle phases of a JSP?JSP page looks like a HTML page but is a servlet. When presented with JSP page the JSP engine does the following 7 phases. Page translation: -page is parsed, and a java file which is a servlet is created. Page compilation: page is compiled into a class file Page loading : This class file is loaded. Create an instance :- Instance of servlet is created jspInit() method is called _jspService is called to handle service calls _jspDestroy is...

What is a class?A class is a blueprint, or prototype, that defines the variables and the methods common to all objects of a certain kind.What is a object?An object is a software bundle of variables and related methods.An instance of a class depicting the state and behavior at that particular time in real world.What is a method?Encapsulation of a functionality which can be called to perform specific tasks.What is encapsulation? Explain with an example. Encapsulation is the term given to the process of hiding the implementation details of the object. Once an object is encapsulated, its implementation details are not immediately accessible any more. Instead they are packaged and are only indirectly accessible via the interface of the objectWhat is inheritanc...

Q1: What are the advantages of OOPL? Ans: Object oriented programming languages directly represent the real life objects. The features of OOPL as inhreitance, polymorphism, encapsulation makes it powerful. Q2: What do mean by polymorphisum, inheritance, encapsulation? Ans: Polymorhisum: is a feature of OOPl that at run time depending upon the type of object the appropriate method is called.Inheritance: is a feature of OOPL that represents the "is a" relationship between different objects(classes). Say in real life a manager is a employee. So in OOPL manger class is inherited from the employee class.Encapsulation: is a feature of OOPL that is used to hide the information. Q3: What do you mean by static methods? Ans: By using the static method th...

Q1: How can we store the information returned from querying the database? and if it is too big, how does it affect the performance?In Java the return information will be stored in the ResultSet object. Yes, if the ResultSet is getting big, it will slow down the process and the performance as well. We can prevent this situation by give the program a simple but specific query statement.Q2: What is index table and why we use it?Index table are based on a sorted ordering of the values. Index table provides fast access time when searching.Q3: In Java why we use exceptions? Java uses exceptions as a way of signaling serious problems when you execute a program. One major benefit of having an error signaled by an exception is that it separates the code that deals wi...

1: What is the three tier model? Ans: It is the presentation, logic, backend2: Why do we have index table in the database? Ans: Because the index table contain the information of the other tables. It willbe faster if we access the index table to find out what the other contain.3: Give an example of using JDBC access the database. Ans: try{Class.forName("register the driver");Connection con = DriverManager.getConnection("url of db", "username","password");Statement state = con.createStatement();state.executeUpdate("create table testing(firstname varchar(20), lastname varchar(20))");state.executeQuery("insert into testing values(’phu’,'huynh’)");state.close();con.close();}catch(Exception e){System.out.println(e);}4: What is the different of an Applet and a Java...

Q: What are the most common techniques for reusing functionality in object-oriented systems?A: The two most common techniques for reusing functionality in object-oriented systems are class inheritance and object composition. Class inheritance lets you define the implementation of one class in terms of another’s. Reuse by subclassing is often referred to as white-box reuse.Object composition is an alternative to class inheritance. Here, new functionality is obtained by assembling or composing objects to get more complex functionality. This is known as black-box reuse. Q: Why would you want to have more than one catch block associated with a single try block in Java? A: Since there are many things can go wrong to a single executed statement, we should have more than one catch(s) to cat...

Q1) What is the purpose of garbage collection in Java, and when is it used? The purpose of garbage collection is to identify and discard objects that are no longer needed by a program so that their resources can be reclaimed and reused. A Java object is subject to garbage collection when it becomes unreachable to the program in which it is used. Q2) Describe synchronization in respect to multithreading. With respect to multithreading, synchronization is the capability to control the access of multiple threads to shared resources. Without synchonization, it is possible for one thread to modify a shared variable while another thread is in the process of using or updating same shared variable. This usually leads to significant errors. Q3) How is JavaBean...

1:In Java, what is the difference between an Interface and an Abstract class? A: An Abstract class declares have at least one instance method that is declared abstract which will be implemented by the subclasses. An abstract class can have instance methods that implement a default behavior. An Interface can only declare constants and instance methods, but cannot implement default behavior. 2: Can you have virtual functions in Java? Yes or No. If yes, then what are virtual functions? A: Yes, Java class functions are virtual by default. Virtual functions are functions of subclasses that can be invoked from a reference to their superclass. In other words, the functions of the actual object are called when a function is invoked on the reference to that obj...

What is a Servlet?Answer: Servlets are modules of Java code that run in a server application (hence the name "Servlets", similar to "Applets" on the client side) to answer client requests.What advantages does CMOS have over TTL(transitor transitor logic)? (ALCATEL)Answer: * low power dissipation * pulls up to rail * easy to interfaceHow is Java unlike C++? (Asked by Sun)Answer:Some language features of C++ have been removed. String manipulations in Java do not allow for buffer overflows and other typical attacks. OS-specific calls are not advised, but you can still call native methods. Everything is a class in Java. Everything is compiled to Java bytecode, not executable (although that is possible with compiler tools).What is HTML (Hypertext Markup Lan...
