  The 20th century was a groundbreaking period for computer technology. From early mechanical calculators to the rise of personal computers and the internet, this century laid the foundation for the digital world we live in today. Many of the advancements that occurred during this time transformed industries, reshaped economies, and revolutionized communication. Below, we’ll explore the most significant computer advancements of the 20th century. 1. The Invention of the First Programmable Computers One of the most important milestones in the 20th century was the invention of programmable computers. In the 1940s, the development of machines like the ENIAC (Electronic Numerical Integrator and Computer), one of the first general-purpose digital computers, revolutionized computing. Built during World War II, ENIAC was capable of performing a wide range of calculations at unprecedented speeds for its time. ENIAC and other early computers like the Colossus and UNIVAC (Universal Automatic C

  The 21st century has seen rapid advancements in technology, particularly in the field of computing. These innovations have transformed the way we live, work, and communicate. From the rise of artificial intelligence to the power of quantum computing, the last two decades have been marked by significant breakthroughs that have redefined the capabilities of computers. Here are some of the most notable advancements in computer technology that have shaped the 21st century. 1. Artificial Intelligence and Machine Learning Artificial intelligence (AI) has arguably been the most transformative advancement in computing in the 21st century. Machine learning, a subset of AI, allows computers to learn from data and improve their performance without explicit programming. From self-driving cars to virtual assistants like Siri and Alexa, AI is embedded in everyday life. Machine learning algorithms have made huge strides in areas like image recognition, natural language processing, and predictive an
