Quantum superposition: what it is and why this concept is fundamental to quantum computing.
When we hear about quantum computing, one of the first concepts that comes up is quantum superposition. It is often cited as one of the main reasons why quantum computers can solve certain problems much more efficiently than traditional computers. Although it seems like an extremely complex topic, the idea behind it […]
Fine-Tuning: What is it and how does AI training work?
You've probably already noticed that artificial intelligence is everywhere. It answers questions, creates images, automates processes, organizes information, and already participates in decision-making within companies. But there's a question that frequently arises when the subject goes a little beyond everyday use: Are AI models trained to […]
Digital Transformation in Companies: How Does it Impact Business?
Technology is no longer just a competitive differentiator. Today, it plays a part in strategic decisions, redefines business models, and directly influences the customer experience. But there's an important difference between simply using technology and undergoing a digital transformation. Many companies already have digital systems, platforms, and channels. Yet, they continue to face problems with […]
From the Turing Machine to Quantum Computing: how computing has evolved over the decades.
Few technologies have transformed society as much as computing. In less than a century, we have gone from machines capable of performing simple calculations to computers present in virtually every aspect of daily life. Today, they assist in everything from scientific research and medical diagnoses to financial transactions, artificial intelligence, and space exploration. This evolution, however, is not the only factor...
Data Security: What is it and how to protect digital information?
There's a scene that repeats itself every day in thousands of companies. An employee opens an email, clicks on a seemingly ordinary link, and within minutes, strategic information is no longer protected. It sounds like an exaggeration. But it's not. As companies become more digital, data is becoming central to their operations. […]
What is a Data Center and how does this Digital Infrastructure work?
There's a physical place behind practically everything we do in the digital environment. When a video call happens without interruptions. When an app responds instantly. When a company analyzes millions of pieces of information in seconds. None of this happens in a vacuum. For a long time, the expression "in the cloud" helped create the feeling of […]
Edge Computing: What is it and how does Edge Computing work?
Have you ever noticed how some technologies seem to respond instantly? A connected car identifies obstacles in seconds. An industrial system corrects faults almost in real time. A navigation app calculates a route immediately. Behind this speed lies an important change in how data is processed. It is in this context that edge computing emerges […]
Computer Networks: Types, topologies, and market
*Written by: Auro de Jesus Cardoso Correia, professor of Computer Engineering at ESEG College. Computer networks are part of practically everything you do today, from sending a message on your cell phone to accessing a system at work. Even without realizing it, we are constantly connected by different types of networks […]
Macroeconomics: What it is, what it studies, and key indicators.
*Written by: Romane Fortes, professor of Economics at ESEG College. Macroeconomics is present in your daily life, even when you don't realize it. When food prices rise, interest rates change, or unemployment increases, all of this is part of a larger scenario that directly influences people's lives, […]
Data Structures: What are they and how to apply them in programming?
Data Structures: What are they and how to apply them in programming? *Written by: Bruno de Abreu Iizuka Moritani, professor of the Computer Engineering course at ESEG College. When someone starts learning programming, it's common to pay more attention to syntax: how to declare variables, use if, for, create functions and classes. But, after a while, a very important question arises: how to organize the program's data efficiently? This is where data structures come in. They are fundamental for a program to function well, be organized, and be able to grow without becoming a mess. This issue appears in practically any system. For example, a messaging application needs to store conversations and display them quickly. A streaming platform organizes thousands of movies and series. A social network deals with profiles, connections, recommendations, and interactions on a large scale. In all these cases, it's not enough to just have data: you need to know how to store, access, and manipulate it. In this text, we will understand the types of data, what data structures are, their relationship with algorithms, and see how these concepts appear in practice in software development. Therefore, continue reading to learn more about the subject! What is a…
