  • Q2. Why is normalization needed in a database?
  • Ans. 

    Normalization is needed in a database to reduce redundancy, improve data integrity, and optimize database performance.

    • Eliminates data redundancy by breaking down data into smaller, more manageable tables

    • Prevents update anomalies by ensuring data consistency

    • Improves data integrity by enforcing relationships between tables

    • Optimizes database performance by reducing storage space and improving query efficiency

  • Q3. Explain the difference between intension and extension in a database.
  • Ans. 

    Intension refers to the attributes or properties of a concept, while extension refers to the instances or examples of that concept in a database.

    • Intension describes the characteristics or properties of a concept.

    • Extension refers to the actual instances or examples of that concept.

    • For example, in a database of fruits, intension would include attributes like color, taste, and size, while extension would list specific fru

  • Q4. What is the difference between new() and malloc() in C++?
  • Ans. 

    new() is used to allocate memory for an object and call its constructor, while malloc() is used to allocate memory without calling any constructor.

    • new() is a C++ operator, while malloc() is a function in C.

    • new() returns a pointer to the allocated memory, while malloc() returns a void pointer.

    • new() automatically calls the constructor of the object, while malloc() does not initialize the allocated memory.

  • Q5. What distinguishes a structure from a class in C++?
  • Ans. 

    In C++, a structure is a user-defined data type that can hold both data and functions, while a class can also have access specifiers and inheritance.

    • Structures in C++ are primarily used for grouping data members together, while classes can have additional features like access specifiers (public, private, protected) and inheritance.

    • Structures default to public access for their members, while classes default to private a...

Round 2 - Face to Face 

(7 Questions)

Round duration - 60 Minutes
Round difficulty - Medium

This round was preety much mixed and contained questions from Operating Systems, Unix, Java and more importantly Selenium.

  • Q1. Can you explain piping in Unix/Linux?
  • Ans. 

    Piping in Unix/Linux allows the output of one command to be used as the input for another command.

    • Piping is done using the '|' symbol.

    • It helps in connecting multiple commands together to perform complex operations.

    • Example: ls -l | grep 'txt' - This command lists all files in long format and then filters for files with 'txt' in their name.

  • Answered by AI
  • Q2. What is memory protection in operating systems?
  • Ans. 

    Memory protection in operating systems is a feature that prevents a process from accessing memory that has not been allocated to it.

    • Memory protection helps prevent one process from interfering with the memory of another process.

    • It ensures that each process can only access memory that has been allocated to it.

    • Examples of memory protection mechanisms include read-only memory segments and memory segmentation.

  • Q3. What happens if the static modifier is not included in the main method signature in Java?
  • Ans. 

    The main method in Java must include the static modifier to be able to run the program.

    • Without the static modifier, the main method cannot be called by the Java Virtual Machine (JVM).

    • The program will not be able to start and will throw a NoSuchMethodError.

    • Adding the static modifier allows the main method to be called without creating an instance of the class.

  • Q4. Can you tell us something about the JIT compiler?
  • Ans. 

    JIT compiler stands for Just-In-Time compiler, which compiles code during runtime for improved performance.

    • JIT compiler translates bytecode into machine code on-the-fly

    • It helps in optimizing performance by compiling frequently executed code paths

    • Examples include Java HotSpot VM's JIT compiler and .NET's JIT compiler

  • Answered by AI
  • Q5. What is XPath?
  • Ans. 

    XPath is a query language used for selecting nodes from an XML document.

    • XPath stands for XML Path Language

    • It is used to navigate through elements and attributes in an XML document

    • XPath uses path expressions to select nodes or content in an XML document

    • Example: //book[@category='fiction'] selects all book elements with category attribute equal to 'fiction'

  • Answered by AI
  • Q6. Can you explain the pause feature in Selenium IDE?
  • Ans. 

    The pause feature in Selenium IDE allows users to pause the execution of a test case for a specified amount of time.

    • The pause command is used to introduce a delay in the test execution.

    • It takes a parameter specifying the time to pause in milliseconds.

    • For example, 'pause 3000' will pause the test execution for 3 seconds.

  • Answered by AI
  • Q7. What are the four parameters that you need to pass in Selenium?
  • Ans. 

    The four parameters needed to pass in Selenium are URL, Port Number, Browser Driver, and Desired Capabilities.

    • URL: The URL of the website you want to automate testing on.

    • Port Number: The port number where the Selenium server is running.

    • Browser Driver: The specific browser driver (e.g. ChromeDriver, GeckoDriver) to use for testing.
