normalization, indexing
Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity. Indexing is a technique to quickly retrieve data from a database.
Normalization helps in reducing data redundancy by breaking down tables into smaller, related tables.
Indexing is used to quickly retrieve data by creating indexes on columns in a table.
Normalization ensures data integrity by minimizing data dupli...

Implement a function that takes in burst times, priorities, and number of processes as input
Sort the processes based on priority, with lower process ID as tiebreaker
Calculate waiting time and turn-around time for each process based on the scheduling algorithm
Data spooling is a process where data is temporarily stored in a buffer before being sent to an output device.
Data spooling helps in managing the flow of data between different devices by storing it temporarily.
It allows for efficient processing of data by decoupling the input/output operations.
Examples of data spooling include print spooling, where print jobs are stored in a queue before being sent to the printer.
Inheritance is a relationship between a superclass and subclass, while generalization is a relationship between entities with common characteristics.
Inheritance involves a parent-child relationship where the child class inherits attributes and methods from the parent class.
Generalization involves grouping entities with common attributes into a higher-level entity.
Inheritance is a specific form of generalization in obje...

Spread operator allows an iterable to be expanded in places where zero or more arguments are expected. Rest operator collects all the remaining elements into an array.
Spread operator is denoted by three dots (...)
Spread operator can be used to copy an array or object
Rest operator is also denoted by three dots (...) and is used in function parameters to collect all remaining arguments into an array
Pure functions are functions that always return the same output for the same input and have no side effects.
Always return the same output for the same input

Promises in JavaScript are objects representing the eventual completion or failure of an asynchronous operation.
Promises help in handling asynchronous operations in a more readable and manageable way.
They can be in one of three states: pending, fulfilled, or rejected.
Promises can be chained together using .then() method to handle success and failure cases.
They help in avoiding callback hell and writing cleaner asynchro...
