Myanatomy Integration Interview Questions and Answers

Node.js is single threaded, but it uses non-blocking I/O operations to handle multiple requests concurrently.

• Node.js runs on a single thread event loop, but it uses worker threads for CPU-intensive tasks.

• It employs asynchronous programming to handle multiple requests without blocking the main thread.

• Node.js can handle multiple requests concurrently by delegating I/O operations to the operating system.

• Example: Using callbacks or Promises in Node.js allows for non-blocking oper...read more

SQL is a relational database management system, while MongoDB is a NoSQL database. MySQL is a specific implementation of SQL, while NoSQL is a category of databases.

• SQL databases are table-based, with a predefined schema, while MongoDB is document-based, using collections and documents.

• SQL databases use structured query language for defining and manipulating data, while MongoDB uses JSON-like documents with dynamic schemas.

• SQL databases are vertically scalable, while NoSQL da...read more

CPU scheduling is done using algorithms like FCFS, SJF, RR, etc. based on priority and burst time.

• Priorities are assigned to tasks based on their importance and urgency

• FCFS (First Come First Serve) algorithm schedules tasks in the order they arrive

• SJF (Shortest Job First) algorithm schedules tasks with the shortest burst time first

• RR (Round Robin) algorithm schedules tasks in a circular queue with a fixed time slice

• Priority scheduling algorithm schedules tasks based on their ...read more

Create a coding assignment for a form

• Include a variety of input fields such as text, number, dropdown, checkbox, radio buttons

• Validate user input to ensure data integrity

• Implement functionality to submit the form and display a success message

Schema defines the structure of a database, Indexes improve query performance, Event Loop manages asynchronous operations.

• Schema is a blueprint of a database that defines tables, columns, relationships, etc.

• Indexes are data structures that improve query performance by allowing faster data retrieval.

• Event Loop is a mechanism that manages asynchronous operations in JavaScript.

• Other important concepts for Full Stack Developers include REST APIs, MVC architecture, and version con...read more

Write a function to generate binary strings without consecutive 1's.

• Use dynamic programming to keep track of previous two states

• Start with base cases of 0 and 1

• For each new bit, check if adding it would create consecutive 1's

• If not, add it to the string and update the previous two states

• Repeat until desired length is reached

LRU cache is a data structure that stores recently used items and discards the least recently used item when the cache is full.

• LRU stands for Least Recently Used

• It is used to improve the performance of applications by reducing the number of disk reads or network calls

• It is commonly used in web browsers, databases, and operating systems

• It can be implemented using a hash table and a doubly linked list

• When an item is accessed, it is moved to the front of the list. When the cache...read more
