What is galvanization?

Galvanization or galvanizing is the process of applying a protective zinc coating to steel or iron, to prevent rusting. There are two types of galvanization:
1.Electro Galvanization or Electro-Plating.
2.Hot-dip Galvanization.

Galvanization protects the steel or iron underneath and can therefore extend the lifespan of metal parts.

Data Structures and Algorithms(DSA)

The term DSA stands for Data Structures and Algorithms, in the context of Computer Science. Data structures refer to how data is organized. The same data can be organized in a variety of ways and an algorithm refers to the set of instructions given to a computer to achieve a particular task.

The Forgetting Curve

In the late 19th century, the German psychologist, Hermann Ebbinghaus tested his memory over various periods of time. Once he’d gathered all the data from his spaced learning studies, he plotted it on a graph that looked a little something like this:

The formula with which the Ebbinghaus curve of forgetting is calculated is the following: R = exp(-t/S), with R symbolizing memory retention, t symbolizing time, and S the relative strength of the memory.

Common types of Databases

A database is a collection of data or records. Database management systems are designed to manage databases. A database management system (DBMS) is a software system that uses a standard method to store and organize data. The data can be added, updated, deleted, or traversed using standard algorithms and queries. There are several types of databases. Here is a chart of common types of Databases:

 

URL Structure Description

Protocol:
HTTP is a protocol used to transfer data across the Web via a client-server (web browser-web server) model. HTTPS encrypts all data that passes between the browser and server using an encryption protocol called Transport Layer Security (TLS), preceded by Secure Sockets Layer (SSL).

Subdomain:
The subdomain or World Wide Web(WWW) is accessible to anyone with an internet connection, providing a vast amount of information at our fingertips. It enables users from all over the world to access and share data, breaking down barriers of distance and time.

Domain Name:
A domain name is a unique, easy-to-remember address used to access websites, such as ‘google.com’, and ‘facebook.com’. Users can connect to websites using domain names.
