Round 2 - One-on-one 

(4 Questions)

  • Q1. Difference between process and threads
  • Ans. 

    Processes are independent instances of a program, while threads are smaller units within a process sharing resources.

    • Processes have their own memory space, while threads share the same memory space within a process.

    • Processes are heavyweight, requiring more resources, while threads are lightweight.

    • Processes communicate with each other through inter-process communication mechanisms, while threads can communicate directly...

  • Q2. What is indexing in DBMS
  • Ans. 

    Indexing in DBMS is a technique used to improve the performance of queries by allowing faster retrieval of data.

    • Indexes are data structures that store a small portion of the table data in an optimized format for quick retrieval.

    • They help in speeding up data retrieval operations like SELECT, UPDATE, DELETE queries.

    • Examples of indexes include primary keys, unique keys, and composite keys.

  • Answered by AI
  • Q3. Examples and description of asymmetric encryption alogorithms
  • Ans. 

    Asymmetric encryption algorithms use a pair of keys to encrypt and decrypt data, providing secure communication.

    • RSA (Rivest-Shamir-Adleman) is a popular asymmetric encryption algorithm.

    • Elliptic Curve Cryptography (ECC) is another commonly used asymmetric encryption algorithm.

    • Asymmetric encryption is slower than symmetric encryption but provides better security.

    • Public key is used for encryption and private key is used f

  • Q4. Which sorting method is beneficial in which scenario
  • Ans. 

    Different sorting methods are beneficial in different scenarios based on factors like time complexity, space complexity, and input size.

    • Quick Sort: Best for large datasets due to its average time complexity of O(n log n)

    • Bubble Sort: Simple and easy to implement, but inefficient for large datasets with its time complexity of O(n^2)

    • Merge Sort: Stable and efficient for large datasets with its time complexity of O(n log n)

Round 3 - One-on-one 

(4 Questions)

  • Q1. What are ACID properties in DBMS
  • Ans. 

    ACID properties are a set of properties that guarantee reliability and consistency in database transactions.

    • Atomicity: Ensures that either all operations in a transaction are completed successfully or none at all.

    • Consistency: Ensures that the database remains in a consistent state before and after the transaction.

    • Isolation: Ensures that the execution of multiple transactions concurrently does not interfere with each ot...

  • Answered by AI
  • Q2. Underlying data structure in Indexing and its time complexity
  • Ans. 

    Indexing typically uses data structures like B-trees or hash tables for efficient retrieval, with time complexity of O(log n) or O(1) respectively.

    • Common data structures for indexing include B-trees and hash tables

    • B-trees are typically used for indexing in databases due to their balanced nature and efficient search operations

    • Hash tables are used for indexing in scenarios where constant time lookup is desired, but may h

  • Q3. Time complexity of a recursive fibonacci code
  • Ans. 

    Time complexity of recursive fibonacci code is O(2^n)

    • The time complexity of a recursive fibonacci code is exponential, O(2^n)

    • This is because each call branches into two recursive calls, leading to exponential growth

    • For example, calculating fibonacci(5) would result in 15 function calls

  • Answered by AI
  • Q4. The protocol behind Web Sockets (because it was in my resume)
  • Ans. 

    Web Sockets is a communication protocol that provides full-duplex communication channels over a single TCP connection.

    • Web Sockets allow for real-time, bi-directional communication between a client and a server.

    • They are commonly used in chat applications, online gaming, and live data streaming.

    • Web Sockets use the ws:// or wss:// protocol scheme in URLs.

    • The protocol is initiated with a handshake between the client and se...
