OOP is a programming paradigm based on the concept of objects, which can contain data in the form of fields and code in the form of procedures.
OOP focuses on creating objects that interact with each other to solve complex problems.
Fundamental concepts include classes, objects, inheritance, encapsulation, and polymorphism.
Classes are blueprints for creating objects, while objects are instances of classes.
Inheritance all...
An array is a data structure that stores a collection of elements of the same type. There are different types of arrays such as one-dimensional, multi-dimensional, and associative arrays.
One-dimensional array: Stores elements in a single row or column.
Multi-dimensional array: Stores elements in multiple rows and columns.
Associative array: Uses key-value pairs to store elements.
Example: ['apple', 'banana', 'orange']
CLR stands for Common Language Runtime, a virtual machine component of the .NET framework responsible for managing code execution.
CLR provides services such as memory management, exception handling, and security.
It compiles code into Intermediate Language (IL) and then translates it into machine code at runtime.
CLR allows for language interoperability within the .NET framework, enabling different languages to work toge

Bubble sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order.
Bubble sort has a worst-case and average complexity of O(n^2), where n is the number of items being sorted.
It is not efficient for large lists and is generally used for educational purposes.
Example: Sorting an array of strings in alphabetical order using bubble sort.
Auto and static are two storage classes in C. Auto variables are local to a function while static variables retain their value between function calls.
Auto variables are created when a function is called and destroyed when the function ends
Static variables are initialized only once and retain their value between function calls
Auto variables have garbage value if not initialized while static variables are initialized to

A deadlock is a situation in which two or more processes are unable to proceed because each is waiting for the other to release a resource.
Occurs in multitasking environments where processes compete for limited resources
Can be resolved using techniques like deadlock prevention, deadlock avoidance, and deadlock detection
Example: Process A holds Resource X and waits for Resource Y, while Process B holds Resource Y and wa
A thread is a lightweight sub-process that allows concurrent execution within a single process.
Threads share the same memory space within a process.
Threads are used to achieve parallelism and improve performance.
Examples of threads include the main thread in a program and worker threads in a multi-threaded application.
Multiprocessing involves multiple processors executing multiple tasks simultaneously, while multiprogramming involves multiple programs sharing a single processor by switching between them.
Multiprocessing utilizes multiple processors to execute multiple tasks concurrently.
Multiprogramming involves multiple programs sharing a single processor by switching between them.
Multiprocessing is more efficient in terms of perfor...
Process life cycle in an operating system involves creation, execution, termination, and resource management.
Creation: When a process is created, it is assigned a unique process ID and allocated necessary resources.
Execution: The process is then scheduled by the operating system to run on the CPU.
Termination: Once the process completes its task or is terminated by the user, it is removed from memory.
Resource Management...

Technical round with questions on DBMS and Networking mainly.
RDBMS is a type of DBMS that stores data in a structured format with relationships between tables.
RDBMS enforces referential integrity and allows for normalization of data.
DBMS is a general term for any system that manages databases, while RDBMS specifically refers to relational databases.
Examples of RDBMS include MySQL, Oracle, and SQL Server.
Examples of DBMS include MongoDB and Redis.
An Object-Oriented Database Management System (OODBMS) is a type of database management system that supports the creation and management of objects in a database.
OODBMS stores data in the form of objects, which can contain attributes and methods.
It allows for complex data structures and relationships to be represented more easily.
Examples of OODBMS include db4o, ObjectDB, and ObjectStore.
Use the COUNT DISTINCT function in SQL to find the number of unique values in a database.
Use the COUNT DISTINCT function along with the column name to count the number of unique values in that column.
For example, SELECT COUNT(DISTINCT column_name) FROM table_name;
You can also use GROUP BY to find the number of unique values for multiple columns.
A hub operates at the physical layer and broadcasts data to all devices on the network, while a switch operates at the data link layer and forwards data only to the intended recipient.

The OSI (Open Systems Interconnection) model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven different layers.
Physical Layer: Deals with the physical connection between devices. Example: Ethernet cables.
Data Link Layer: Responsible for node-to-node communication. Example: MAC addresses.
Network Layer: Manages routing of data packets. Example: IP addresses.

Garbage collection is necessary to free up memory occupied by unused objects. Java uses automatic garbage collection.
Garbage collection helps prevent memory leaks and improves performance.
Java uses a mark-and-sweep algorithm to identify and remove unused objects.
The JVM periodically checks for unused objects and frees up memory occupied by them.
Developers can also manually trigger garbage collection using System.gc() m...
TCP is a connection-oriented protocol while UDP is connectionless.
TCP provides reliable data transfer while UDP does not guarantee reliability.
TCP uses flow control and congestion control while UDP does not.
TCP is slower than UDP due to the overhead of establishing and maintaining a connection.
UDP is faster than TCP for applications that can tolerate data loss such as video streaming or online gaming.
UDP is used in scenarios where speed is more important than reliability, such as online gaming and video streaming.
UDP is a connectionless protocol that does not guarantee delivery of packets
It is faster than TCP because it does not have to establish a connection before sending data
UDP is commonly used in online gaming, video streaming, and VoIP applications
It is also used for broadcasting and multicasting data to mult
The probability that three ants running on the edges of an equilateral triangle will never meet is 1/3.
The ants will never meet if they all move in the same direction (clockwise or counterclockwise) at the same speed.
The probability of this happening is 1/3, as each ant has two possible directions to choose from.
Example: If one ant starts moving clockwise, the other two ants must also move clockwise to never meet.

STL knowledge and finding loop in linked list
STL (Standard Template Library) is a C++ library that provides containers, algorithms, and iterators.
To find a loop in a linked list, we can use Floyd's cycle-finding algorithm.
In this algorithm, we use two pointers, one moving at a slower pace and the other at a faster pace.
If there is a loop in the linked list, the faster pointer will eventually catch up to the slower poin...
