Technical Interview round with questions on OOPS and OS mainly.

  • Q1. What are Little Endian and Big Endian in the context of computer architecture?
  • Ans. 

    Little Endian and Big Endian refer to the order in which bytes are stored in computer memory.

    • Little Endian stores the least significant byte first, while Big Endian stores the most significant byte first.

    • Little Endian is commonly used in x86 architecture, while Big Endian is used in architectures like SPARC and PowerPC.

    • Endianness can affect data transmission between systems with different byte orders.

  • Answered by AI
  • Q2. Write a program to determine if your system is little-endian or big-endian.
  • Ans. 

    Program to determine system's endianness

    • Check the endianness by storing a multi-byte integer and checking the byte order

    • Use bitwise operations to extract the least significant byte

    • If the least significant byte is at the lowest memory address, it's little-endian

    • If the least significant byte is at the highest memory address, it's big-endian

  • Answered by AI
  • Q3. What is the volatile keyword in programming?
  • Ans. 

    The volatile keyword in programming is used to indicate that a variable's value can be changed unexpectedly.

    • Volatile keyword is used in multithreaded programming to prevent compiler optimizations on variables that can be changed by other threads.

    • It tells the compiler not to cache the variable's value in a register, ensuring that every access is made to the variable's memory location.

    • Commonly used in embedded systems pr...

  • Answered by AI
  • Q4. What is the use of a function pointer in C?
  • Ans. 

    Function pointers in C are used to store the address of functions, allowing for dynamic function calls and callbacks.

    • Function pointers can be used to implement callbacks in event-driven programming.

    • They can be used to switch between different functions at runtime.

    • Function pointers are commonly used in implementing data structures like function pointers in an array of function pointers.

    • Example: void (*funcPtr)(int) = &a

  • Answered by AI
  • Q5. Design a data structure to implement multi-threading.
  • Ans. 

    Design a data structure for multi-threading

    • Use a thread-safe queue to manage tasks for each thread

    • Implement a lock or semaphore to control access to shared resources

    • Consider using condition variables for synchronization

    • Use atomic operations for shared variables to prevent race conditions

  • Answered by AI
  • Q6. What does a kernel do?
  • Ans. 

    The kernel is the core component of an operating system that manages system resources and provides a bridge between software and hardware.

    • Manages system resources such as CPU, memory, and I/O devices

    • Provides a bridge between software applications and hardware components

    • Handles tasks such as process scheduling, memory management, and device drivers

    • Controls communication between hardware and software layers

  • Answered by AI
  • Q7. What is a storage class in programming?
  • Ans. 

    A storage class in programming defines the scope and lifetime of variables.

    • Storage classes include auto, register, static, and extern.

    • Auto variables are created when a function is called and destroyed when the function ends.

    • Register variables are stored in CPU registers for faster access.

    • Static variables retain their value between function calls.

    • Extern variables are declared outside of any function and can be accessed
