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.

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...read more

• 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

Q2. What is a namespace in C++?
Ans. 
A namespace in C++ is a declarative region that provides a scope for the identifiers within it.
• Namespaces help in organizing code by grouping related classes, functions, and variables.

• They prevent naming conflicts by allowing the same name to be used in different namespaces.

• Example: namespace myNamespace { int x; }

• Example: using namespace std; // for using standard library functions without prefix

Q3. Why do we need the Friend class and function in Object-Oriented Programming?
Ans. 
Friend class and function in OOP allows specific classes or functions to access private and protected members of a class.
• Friend class/function can access private and protected members of a class without violating encapsulation.

• It allows for selective sharing of data between classes without exposing all members to the outside world.

• Friendship is not mutual - a class can declare another class as a friend, but the other c...read more

Q4. What does a static member in C++ mean?
Ans. 
A static member in C++ is a member of a class that is shared among all instances of the class.
• Static members are declared using the 'static' keyword.

• They are not associated with any specific instance of the class, but rather with the class itself.

• They can be accessed using the scope resolution operator '::'.

• Static members are commonly used for constants, utility functions, or shared data among all instances of a class.

Q2. Can you describe the OSI Reference Model?
Ans. 
The OSI Reference Model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven layers.
• The OSI Reference Model stands for Open Systems Interconnection Reference Model.

• It consists of seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

• Each layer has specific functions and communicates with the adjacent layers.

• The model help...read more

Q3. What is the use of a router and how does it differ from a gateway?
Ans. 
A router is a networking device that forwards data packets between computer networks. It differs from a gateway in terms of functionality and scope.
• A router operates at the network layer of the OSI model, making decisions based on IP addresses.

• Routers connect multiple networks together and determine the best path for data to travel.

• Gateways, on the other hand, translate between different types of networks or protocols.
