Tech and Programming Blog

I always wanted to blog on Web development, App development, and Browser Extensions development, so from now on, you’ll see regular updates on these topics and their projects. Now let's start our day without any delay. First things first, You can write these codes on any text editor, even the notepad is good. If you’re starting your journey in web development, the very first thing you will come across is HTML . Before learning programming languages like JavaScript or frameworks like React, it’s important to understand the foundation of the web. Today, let’s begin with the basics — What is HTML, and how do webpages actually work? What is HTML? HTML (HyperText Markup Language) is the standard language used to create webpages. It doesn’t behave like a programming language — instead, it structures the content of a page. Think of HTML as the skeleton of a website. With HTML, you define: Headings & paragraphs Images & videos Buttons & links Forms & user input fields Pag...

Introduction In C++, searching is a fundamental operation used to locate a specific value inside an array, list, or collection of data. Searching is one of the most important concepts in programming because it helps us find required information quickly and efficiently. There are two common types of searching techniques in C++: Linear Search and Binary Search . Linear search checks each element one by one until the target is found, making it simple but slower for large data sets. Binary search, on the other hand, works on sorted data and divides the list repeatedly to locate the value faster. Understanding these searching methods helps developers optimize performance, manage data effectively, and prepare for more advanced topics like algorithms and data structures. Let’s Explore Searching Algorithms in C++ Today, we going to use searching techniques in C++. In any programming language, we have a few searching techniques which helps us to find specific elements in large lists, o...

In today’s digital world, the internet feels like magic—open a browser, type a website name, and the page appears in seconds. But behind that simple action, a massive network of cables, servers, signals, and protocols are working together 24/7. So, how does the internet actually work? Let’s break it down in the simplest way possible. What Exactly Is the Internet? The internet is a global network of millions of computers connected together. Think of it like a giant transportation system, but instead of cars and roads, it transports data between devices. In short: Your device ➝ Sends data Routers & servers ➝ Transport data Website server ➝ Sends back information Your browser ➝ Displays the website How Data Travels Across the Internet When you search something on Google or open YouTube, here’s what happens step-by-step: 1. Your Device Sends a Request You type a website (like google.com ) in your browser. This request leaves your device and travels to your route...

Artificial Intelligence (AI) is everywhere — from your phone’s camera to self-driving cars. But while AI brings exciting innovations, it’s also driving up hardware costs worldwide . In this article, we’ll explore why hardware is getting more expensive, how AI contributes to it, and what this means for consumers, businesses, and the future of technology. What Is Driving Up Hardware Prices? In the past decade, we’ve seen steep price increases in: GPUs (Graphics Processing Units) CPUs (Central Processing Units) Specialized AI chips Memory (RAM) and storage Networking equipment While inflation and supply chain issues are factors, AI demand is one of the biggest drivers behind this trend. 1. AI Requires More Powerful Hardware AI workloads — especially training large models — need powerful processing units. Traditional CPUs are no longer enough. Instead, companies are investing in: GPUs (Graphics Processing Units) TPUs (Tensor Processing Units) NPUs (Neural Proce...

Introduction In C++, abstraction is a core principle of object-oriented programming that focuses on hiding complex implementation details and only showing the essential features of a system. It helps programmers reduce complexity by separating "what something does" from "how it actually works." Abstraction can be achieved using abstract classes and pure virtual functions , which provide a common structure that other classes can build upon. By designing programs with abstraction, we create cleaner code, avoid unnecessary confusion, and allow users to interact with functions and objects without needing to understand their internal logic. This makes programs easier to maintain, update, and expand over time. Let’s Explore Abstraction in C++ Today, we going to use Abstraction in C++.  Abstraction in C++ is a fundamental principle of object-oriented programming (OOP) that involves simplifying complex systems by hiding unnecessary implementation details and showing on...

Introduction In C++, polymorphism is an important concept of object-oriented programming that allows one function or method to behave differently depending on the object that calls it. The word polymorphism means "many forms," and it helps us write flexible and reusable code. With polymorphism, one interface can represent different forms of behavior, making it easier to handle related objects through a common structure. In C++, polymorphism is mainly achieved through function overriding and virtual functions , which allow a derived class to provide a specific version of a method already defined in the base class. This helps programs become more organized, extendable, and easier to scale. Let’s Explore Polymorphism in C++ Today, we going to use Polymorphism in C++. Polymorphism in C++ is a core concept of object-oriented programming that allows a single interface to be used for multiple types of operations. The word itself means "many forms" (from Greek "p...

Today, we’re going to talk about something you hear everywhere in the world of technology — Databases . Whether you use a mobile app, log into a website, watch videos, or even shop online — a database is working behind the scenes every single time. But what exactly is a database, and why is it so important? Let’s break it down simply. What Is a Database? A database is a structured system where data is stored, organized, and managed so it can be easily accessed whenever needed. Think of it like a digital version of a library: Books = Data Shelves = Tables Librarian = Database Management System (DBMS) Just like you can find a specific book in a library, a database helps you find specific information instantly. Why Do We Need a Database? Because we deal with huge amounts of information every day. Without databases: Apps would lose user data Websites wouldn’t remember logins Banks couldn’t track transactions Hospitals couldn’t store patient records So, a database keeps everything organiz...

Today, we’re talking about one of the most important concepts in modern programming — OOP: Object-Oriented Programming . If you’re learning languages like C++, Java, Python, or even JavaScript, you’ll hear about OOP again and again. But what exactly is it, and why is it so important? Let’s break it down in a simple way. What Is OOP? Object-Oriented Programming (OOP) is a programming approach where everything is built around objects . An object is a real-world entity — like a car, a student, a bank account, etc. Each object has: Data (properties) → like name, age, speed, balance Actions (functions/methods) → like drive(), deposit(), login() So instead of writing a program as one long script, OOP organizes it into objects that interact with each other. This makes programs easy to understand, manage, and reuse. Four Pillars of OOP These four concepts are the foundation of Object-Oriented Programming: 1.  Encapsulation Wrapping data and related functions into a s...

Introduction In C++, encapsulation is a fundamental concept of object-oriented programming that focuses on protecting data from direct access and unauthorized modification. It works by combining data (variables) and functions (methods) into a single unit known as a class , and controlling access through visibility keywords like private , protected , and public . The idea is that sensitive information should remain hidden inside a class, and only specific functions should be allowed to manage or update that data. By using encapsulation, we can build secure, structured, and more reliable programs where important values are accessed safely through methods such as getters and setters . Let’s Explore Encapsulation in C++ Today, we going to use Encapsulation in C++.  Encapsulation is a core object-oriented programming (OOP) concept that involves bundling the data (attributes/variables) and the functions (methods) that operate on that data into a single unit, which is a class. The f...

When learning programming, one of the first concepts students come across is how code actually runs on a computer. This is where two important terms appear: Compiler and Interpreter . Both do the job of translating human-written code into machine language, but they work in different ways. Understanding these differences helps you choose the right programming language and improves the way you write code. What Is a Compiler? A compiler translates the entire program (source code) into machine code before it runs. After compilation, it generates an executable file (like .exe on Windows) that can be run independently. How It Works You write code Compiler checks the full program Converts it into machine language Creates a final executable file Key Features Translates the whole program at once Faster execution once compiled Shows errors after full compilation Produces an executable file Examples of Compiled Languages C C++ Rust Go Java (c...
