#First Generation Computer Eniac

Computer 1st Generation. First Generation Computers (1940–1956) First generation computers were the earliest computers and used vacuum tubes for processing. They were very large in size, consumed a lot of electricity, and produced excessive heat. These computers were slow, expensive, and could only perform basic calculations. Programming was done using machine language, and examples include ENIAC and UNIVAC.

Today marks the 80th anniversary of ENIAC, the first programmable, electronic, general-purpose computer. This feat of engineering ushered in a new era of technology, faster and more powerful than anything before. In this video, Penn Engineering's Paul Shaffer shares fast facts about ENIAC and reflects on eight decades of technological change. Happy 80th anniversary, ENIAC!

Did you know that in 1943, six women programmed the world’s first modern computer? Entirely from scratch! 🤯  Here’s a mini-history lesson from our Content Marketing Manager Cory on how the “ENIAC Six” basically invented computer programming and laid the foundation for future tech. 👆 #WomensHistoryMonth #WomenInTech #WomenInSTEM *** Photos credited to the Computer History Museum, CORBIS/Getty Images Videos credited to Computer History Archives Project and ENIAC Programmers Project

A incrível evolução dos computadores entre 1946 - 2010. O Eniac custou 487.000 dólares para ser construído (mais de 7 milhões de dólares em valores atualizados) vs 999 dólares do Macbook Air em 2010. Sem contar que o Macbook tem capacidade computacional mais de 1 milhão de vezes maior do que o Eniac. Vídeo: @evolutionwith.ai Dica de vídeo: @jeferbd

A Evolução do Computador. Dos enormes painéis do ENIAC em 1940, que ocupavam salas inteiras e realizavam cálculos militares, até o MacBook da Apple em 2010. Os computadores passaram por uma transformação impressionante com sua evolução tecnológica permitiu que máquinas complexas se tornassem acessíveis, rápidas e integradas ao nosso dia a dia de cada pessoa. Cada avanço dos transistores aos microprocessadores, da interface de texto à interface gráfica moldou o mundo moderno e abriu caminho para a era digital que vivemos hoje.

In 1946, the first electronic computer changed the course of technology. Six women—Kathleen McNulty, Jean Jennings Bartik, Betty Snyder, Marlyn Wescoff, Frances Bilas, and Ruth Lichterman—designed the programming methods that allowed ENIAC to execute complex calculations. At the time, there were no programming languages, no compilers, and no established field of software engineering. They worked directly with the machine’s architecture: configuring switches, cables, and logic flows to translate mathematical problems into operational instructions. Many of the concepts they developed, structured problem decomposition, execution sequencing, and logical debugging, became foundational practices in modern software development. International Women’s Day is a moment to acknowledge that legacy, and to keep building technology with the same curiosity and determination that started it all!

O INÍCIO DA ERA DIGITAL: O ENIAC (1946) 💻🔹 Você sabia que o primeiro computador eletrônico da história foi criado em 1946? Seu nome era ENIAC (Electronic Numerical Integrator and Computer), e ele mudou para sempre o mundo da tecnologia! ⚙️ Criado por John Presper Eckert e John Mauchly na Universidade da Pensilvânia, o ENIAC pesava cerca de 30 toneladas, ocupava uma sala inteira e consumia energia suficiente para iluminar uma cidade pequena! 😱 🧠 Especificações impressionantes para a época: 17.468 válvulas eletrônicas 7.200 diodos de cristal 1.500 relés 70 mil resistores 10 mil capacitores E mais de 5 milhões de pontos de solda! Sua capacidade de memória era mínima comparada a um simples celular de hoje — ele armazenava apenas 20 números de 10 dígitos cada. Mas, naquela época, isso era revolucionário! ⚡ O ENIAC conseguia realizar 5 mil somas por segundo e cálculos complexos em minutos — tarefas que antes demoravam semanas! Era usado principalmente para cálculos balísticos e projetos científicos, abrindo caminho para os computadores modernos que hoje cabem na palma da nossa mão 📱💻 O ENIAC não tinha monitor, teclado ou mouse — os cálculos eram programados manualmente com cabos e interruptores, exigindo horas de preparação para cada operação. 🧩 ✨ Ele marcou o nascimento da computação moderna e inspirou toda a evolução tecnológica que vivemos hoje: da internet aos notebooks gamers, dos servidores à inteligência artificial. 🚀 O ENIAC provou que a mente humana é capaz de transformar o impossível em realidade. Nunca subestime o poder da inovação, curiosidade e conhecimento — foi assim que começou a revolução digital que move o mundo atual! 🌍 #tecnologia #windows #hardware #gamer #engenharia #homeoffice #inovacao #trabalho #work #life #motivacional #futuro #inteligenciaartificial #processador #computador #ciencia #historia #ensinotecnologico #aprendizado #cpu #memoria #curiosidades #mundoTech #educacaoDigital #historiaDaTecnologia

The world’s first general-purpose computers, such as ENIAC, were massive machines occupying entire rooms, filled with thousands of vacuum tubes and consuming huge amounts of power. Despite their size, they were far less powerful than today’s basic calculators or smartphones, performing calculations at speeds that are now considered extremely slow. These early systems, however, laid the foundation for the rapid evolution of modern computing.

The first generation of computers (1940–1956) changed the world forever. These massive machines used vacuum tubes to process data and were so huge they could fill an entire room. One of the most famous was ENIAC, weighing about 30 tons with 18,000 vacuum tubes, capable of performing thousands of calculations per second. Another milestone was UNIVAC I, the first commercial computer that even predicted the 1952 U.S. election correctly. Although these computers were extremely expensive, produced intense heat, and required constant maintenance, they proved that electronic machines could solve complex problems faster than humans. These giant machines became the foundation of modern computers, leading to the powerful smartphones and laptops we use today. 💻🚀 👍 Like | 💬 Comment | 🔁 Share | ➕ Follow for more amazing tech facts and history #technology #computer #computerscience #machine #firstgeneration

The world’s first general-purpose electronic computer, ENIAC (Electronic Numerical Integrator and Computer), was an enormous machine that filled an entire room. Built in the 1940s, it contained thousands of wires, switches, and vacuum tubes, consuming huge amounts of electricity and generating significant heat. Despite its massive size, ENIAC had very limited memory and processing power compared to today’s devices. Modern computers, including smartphones and laptops, are millions of times faster, smaller, and more efficient.
