Random forest is an ensemble learning method that builds multiple decision trees and merges them to improve accuracy and prevent overfitting.
Random forest is a type of ensemble learning method.
It builds multiple decision trees during training.
Each tree is built using a subset of the training data and a random subset of features.
The final prediction is made by averaging the predictions of all the individual trees.

Boosting is a machine learning ensemble technique where multiple weak learners are combined to create a strong learner.
Boosting is an iterative process where each weak learner is trained based on the errors of the previous learners.
Examples of boosting algorithms include AdaBoost, Gradient Boosting, and XGBoost.
Boosting is used to improve the accuracy of models and reduce bias and variance.

Routing protocols are used to determine the best path for data to travel between networks.
There are two types of routing protocols: distance-vector and link-state.
Distance-vector protocols are simpler but less efficient than link-state protocols.
Examples of distance-vector protocols include RIP and IGRP.
Examples of link-state protocols include OSPF and IS-IS.
Routing protocols have different metrics to determine the bes...

Interface defines a contract while abstract class provides partial implementation.
Interfaces can only have abstract methods while abstract classes can have both abstract and non-abstract methods.
A class can implement multiple interfaces but can only inherit from one abstract class.
Interfaces are used for loose coupling while abstract classes are used for code reusability.
Example of interface: Runnable interface in Java...
Method overloading is when a class has multiple methods with the same name but different parameters.
Method overloading allows for flexibility in method calls
The methods must have different parameters, such as different data types or different numbers of parameters
Example: public void print(int num) and public void print(String str)
The compiler determines which method to call based on the arguments passed
Indexing in SQL Server database
Indexing improves query performance by creating a structure that allows for faster data retrieval
Clustered and non-clustered indexes are the two types of indexes in SQL Server
Clustered indexes determine the physical order of data in a table while non-clustered indexes create a separate structure
Indexing should be done strategically to avoid over-indexing which can slow down data modificat
