The first Macintosh was introduced on January 24, 1984, by Steve Jobs and was the first commercially successful personal computer to include two well-known, but still unpopular, features: the mouse and the graphical user interface.

IBM PC Convertible

Introduced to the public in 1986, the IBM PC Convertible was IBM's first portable computer. This revolutionary computer weighed less than 6 kilos and cost approximately $2,000.

Z3

ENIAC (Electronic Numerical Integrator and Computer) was the first general-purpose electronic computer, built in 1945 in the United States. It used vacuum tubes and could perform thousands of calculations per second. ENIAC was used mainly for military calculations and marked the beginning of the electronic computing era.

Apple I (1976)

The Apple I was one of the first personal computers, created by Steve Wozniak and Steve Jobs in 1976. It came as a fully assembled circuit board, which was rare at the time. The Apple I helped launch the personal computer revolution.

Zuse Z1

In 1936, German engineer Konrad Zuse created the Z1, often regarded as the first programmable mechanical computer. It was built in his parents’ living room and used binary numbers, something revolutionary for the time. Although it was unreliable and never fully functional, the Z1 represented a critical step toward modern programmable computers.

UNIVAC I

estebanpartida867 — 2025-08-28 05:57:08 UTC

In 1951, the UNIVAC I (Universal Automatic Computer I) became the first computer sold commercially in the United States. Unlike its predecessors, it was designed for business and government applications, such as census calculations and data processing. Its arrival marked the transition of computers from purely military and scientific tools to business and commercial use.

Turing Machine

estebanpartida867 — 2025-08-28 06:03:26 UTC

In 1936, Alan Turing designed the concept of the “Turing Machine,” a theoretical model that could solve any mathematical problem using logic. Although it was not a physical machine at the time, this idea laid the foundation for modern computer science.

The IBM 701 Electronic Data Processing Machine, known as the Defense Calculator while in development, was IBM's first commercial scientific computer and its first series production mainframe computer, which was announced to the public on May 21, 1952

The Z1 was an early, motor-driven mechanical computer designed by Konrad Zuse in Germany between 1936 and 1938. It was a significant innovation as the world's first freely programmable computer to use binary logic and floating-point numbers, reading instructions from a punched tape. Though unreliable and destroyed during World War II, the Z1 laid the foundation for modern computers by establishing key concepts like binary arithmetic and memory storage.

ENIAC fue el primer ordenador de propósito general y totalmente digital. Diseñado por John Presper Eckert y John William Mauchly en la Universidad de Pensilvania en 1943, su objetivo principal era calcular trayectorias balísticas para el ejército de los EE. UU. en plena Segunda Guerra Mundial.

Herman Hollerith’s Tabulating Machine

marioanqm — 2025-09-03 04:56:46 UTC

Created to process the U.S. Census, it used punched cards and reduced data analysis time from years to months. This invention later led to the foundation of IBM.

Invention of the Transistor

marioanqm — 2025-09-03 04:58:26 UTC

Developed at Bell Labs, the transistor replaced vacuum tubes, making computers smaller, faster, and more energy-efficient.

First Commercial Microprocessor (Intel 4004)

marioanqm — 2025-09-03 04:59:36 UTC

Intel launched the 4004, the first microprocessor integrated on a single chip, marking the beginning of the personal computer era.

EDSAC 1949

2025-09-03 05:06:19 UTC

A team at the University of Cambridge develops the Electronic Delay Storage Automatic Calculator (EDSAC), "the first practical stored-program computer," according to O'Regan. "EDSAC ran its first program in May 1949 when it calculated a table of squares and a list of prime numbers," O'Regan wrote.

COBOL 1953

Grace Hopper develops the first computer language, which eventually becomes known as COBOL, which stands for COmmon, Business-Oriented Language according to the National Museum of American History. Hopper is later dubbed the "First Lady of Software" in her posthumous Presidential Medal of Freedom citation.

AMD 2003

monserratc698 — 2025-09-03 05:14:01 UTC

AMD's Athlon 64, the first 64-bit processor for personal computers, is released to customers.
