INTRODUCTION
COMPUTER
First of all, we have to know what a computer is, a computer it´s a programmable electronic machine that processes data to produce information. Nowadays, it´s used to perform a wide variety of tasks, from complex calculations to communication and entertainment.
They were mainly created in the XX century for problem solving and quick calculations, innitially for military and scientific use, but little by little they were evolved to the point of becoming essential tools in daily life and the global economy.
1950-60
XIX-XX
Second generation: transistors
Antecedents
1940-50
First generation: Vacuum valves
1970-80
Fourth generation: Microprocessors and Personal Computers
1990- PRESENT
1960-70
From Modern Computing to the Digital Age
Third generation: Integrated circuits
THE MICROPROCESSOR: Intel launched the first commercial microprocessor, the Intel 4004, in 1971, making personal computers possible. RISE OF THE PC: Companies like Apple (with its Apple II in 1977) and IBM (with the IBM PC in 1981) revolutionized computing with their personal computers, marking a shift toward individual use.
KEY BREAKTHROUGH: The introduction of transistors replaced vacuum tubes, making computers smaller, faster, more efficient, and cheaper.
MINIATURIZATION: The invention of the integrated circuit (chip) made it possible to place multiple components on a single board, further reducing size and improving capacity. TIME-SHARING COMPUTERS: Computers became more affordable for universities and businesses.
CHARLES BABBAGE (1837): He designed the Analytical Engine, a general-purpose mechanical computer with key elements of modern computers, such as the arithmetic unit and memory.ADA LOVELACE: She collaborated with Babbage and is considered the creator of the first computer program in history.
INTERNET: Tim Berners-Lee created the World Wide Web (WWW) in 1990, transforming the way we interact with the Internet. MOBILE DEVICES: The arrival of the first iPhone in 2007 marked the beginning of smartphones and the integration of computing into our daily lives.
FIRST ELECTRONIC MACHINES: World War II accelerated research, leading to machines like the ENIAC (1946), an experimental electronic digital computer that used thousands of vacuum tubes and occupied an entire room. INNOVATIONS: They were programmed in machine language and used punched cards for data entry. COMMERCIALIZATION: The UNIVAC I was the first commercial computer, launched in 1951.
