Related Topics Node JS Question 11 Explain the single-threaded event loop model in Node.js and how it enables efficient server-side programming? Answer Sure, the single-threaded event loop model is a core concept in Node.js and enables efficient server-side programming by allowing Node.js to handle large numbers of concurrent requests with a low overhead. In a […]
Related Topics Node JS Question 6 How does Node.js handle I/O operations and what advantages does it provide compared to traditional servers? Answer Node.js handles I/O operations using an event-driven, non-blocking I/O model. In traditional servers, when a request comes in that requires I/O, such as reading data from a file or a database, the
Related Topics Node JS Question 1 Explain what Node.js is and its purpose? Answer Node.js is an open-source, cross-platform, server-side runtime environment built on the Google V8 JavaScript engine. It allows developers to run JavaScript on the server side, providing a powerful and efficient way to build scalable, real-time applications. The primary purpose of Node.js

Answer The Master File Table (MFT) is a crucial component of the NTFS file system used in modern versions of Windows. The MFT serves as a central database that keeps track of all the files
Related Topics Data Structure Question 268 Explain what a file system is and its purpose? Answer A file system is a way of organizing and storing files on a storage device such as a hard disk drive, solid-state drive, or flash drive. Its purpose is to provide a hierarchical structure for the files and directories
Related Topics Data Structure Question 263 Example of a use case for hash tables? Answer Suppose you are building a web application that stores user login information in a database. When a user logs in, the application needs to quickly retrieve their login credentials based on their username. One way to do this would be
Related Topics Data Structure Question 258 What is a hash function and what is its purpose? Answer A hash function is a mathematical function that takes in an input (or “key”) and produces a fixed-size output, known as a hash or a digest. The purpose of a hash function is to convert data of arbitrary
Related Topics Data Structure Question 251 What is the time complexity of merge sort and quick sort? Answer The time complexity of merge sort and quick sort are both O(n log n) in the average and worst cases. Merge sort has a guaranteed worst-case time complexity of O(n log n), as it divides the array
Related Topics Data Structure Question 243 Explain the difference between linear search and binary search? Answer Linear search and binary search are two algorithms used to search for a target value in a list or an array. Linear search, also known as sequential search, is a simple algorithm that starts at the beginning of the
Related Topics Data Structure Question 236 Explain the concept of a minimum spanning tree (MST) and how to find it (e.g. Kruskal’s algorithm, Prim’s algorithm)? Answer A minimum spanning tree (MST) is a tree that spans all the vertices of a connected, undirected graph with the minimum possible total edge weight. In other words, it
