Database Sharding

Splitting a database into smaller pieces (shards) distributed across multiple servers to handle more data and traffic.

Databases

DDoS Attacks

A DDoS (Distributed Denial of Service) attack overwhelms a server with excessive traffic to make it unavailable.

Fault Tolerance

The ability of a system to continue operating correctly even when components fail.

System Design

Frontend Development

Frontend development is responsible for how websites and applications are developed using HTML, CSS, and JavaScript to visually render data from backend services and databases.

Frontend

Functional Programming

A programming paradigm that treats computation as the evaluation of mathematical functions and avoids changing state and mutable data.

H

HTTP Status Codes

Three-digit numbers that servers send to indicate the result of an HTTP request (success, error, redirect, etc.).

Backend

HyperText Markup Language (HTML)

HyperText Markup Language (HTML) is the standard markup language used for creating and structuring the content of web pages. It provides a set of tags and attributes that define the structure and formatting of text, images, links, and other elements within a web document. HTML is the backbone of the World Wide Web.

JWT (JSON Web Token)

JavaScript

JavaScript (JS) is a versatile and widely-used programming language primarily adopted in web development. It enables the creation of interactive and dynamic elements within web pages, allowing for enhanced user experiences. JavaScript runs on the client side, meaning it executes directly in a user's web browser without the need for server interaction.

Frontend

JSON

JavaScript Object Notation - a lightweight format for storing and exchanging data between applications.

Frontend

JWT (JSON Web Token)

JWT is a secure method to transmit authentication tokens between a client and a server.

Lazy Loading

Lazy Loading

A design pattern that defers the loading of non-critical resources (like images) until they are needed, improving initial page load time.

Pair Programming

Pair Programming is a collaborative coding technique where two developers work together on the same task. One person is the "Driver" (writes the code), and the other is the "Navigator" (reviews, suggests improvements, and strategizes). This method improves code quality, problem-solving, and knowledge sharing.

Server-Side Rendering

SSR (Server-Side Rendering) means a webpage is generated on the server before being sent to the browser. Instead of sending an empty HTML file and letting JavaScript build everything on the client, the server prepares the page with content and sends a ready-to-display HTML file to the browser. This makes the page load faster, improves SEO, and is great for dynamic content that changes based on user requests.
