How did the computer come about?

MARK 1 – 1944

The first electronic computers appeared at the same time in Germany, England and in the United States, home of the Mark 1. With 4.5 tons, it took six seconds to multiply!

ENIAC – 1946

This Eniac was the first “multipurpose” computer – the previous ones only performed specific tasks, such as calculations of bombings in war

EDVAC – 1946

This ENIAC “puppy” changed the data storage system, changing the decimal system (from 0 to 9) to the binary system (0 or 1). The change made possible the creation of bits of information

TRANSISTOR – 1947

Early computers used huge components, tubes, to store information and do math. The transistor did the same thing, but it was smaller, cheaper, and used less power.

LEO – 1951

The first machines were used in war or in universities. That was until the arrival of Leo, employed by an English food company, the first to use a computer in business.

WHIRLWIND – 1953

This computer was the fastest of its time: it did a multiplication in 0.025 seconds. But it was still a wagon, equivalent today to the speed of a 1 MHz processor.

TRADIC – 1955

Made for the US Air Force, this was the first computer to use transistors. With them, computers became faster, lighter and more economical.

INTEGRATED CIRCUIT – 1958

With the invention of the IC – several transistors integrated into a single piece of silicone – the speed of machines increases

PDP-1 – 1960

As the computer became more versatile, new applications for the invention began to pop up. And it didn’t take long for the first video game to appear: in 1960, it was already possible to play SpaceWar on the PDP-1

ATLAS – 1962

It was in this English invention that the first virtual memory appeared, a technology still used today that allows working with different programs at the same time.

PDP-8 – 1965

This machine was the first to fit on top of a table – the feat earned it the nickname minicomputer. Cheap, it became a commercial success, with 300,000 units sold

SYSTEM 360 – 1965

The integrated circuit is built into the computers in this IBM model. The development of this component increases the processing speed and storage space of the machines

MOUSE – 1968

The American Douglas Engelbart launched a device called “bug”. He didn’t get much success until the 1980s, when he got the nickname «the mouse».

MICROPROCESSOR – 1971

With the decrease of integrated circuits, the industry managed to condense thousands of them into a single piece, launching the first microprocessor, the Intel 4004

ALTAIR 8800 – 1974

The microprocessor debuted in the world of computers aboard an Altair 8800. Small for the time, this machine paved the way for the personal computer revolution

MICROSOFT – 1975

Two American students, Bill Gates, 19, and Paul Allen, 22, adapt the basic language for Altair. This is Microsoft’s first program

Apple II – 1977

The Apple II was the first microcomputer as we know it. For the first time, the machine had a keyboard and could be connected to a monitor – in this case, a TV.

DISKETTE OF 2/31 – 1981

In 1976, the 5 1/4 floppy disk (13 cm in diameter) appears. In 1981, Sony launches the 3 1/2 model (9 cm in diameter)

IBM-PC – 1981

The PC puts IBM at the forefront of the microcomputer market. The price of US$2,820 was higher than that of competitors, but the machine exploded: in 4 months, 35,000 units were sold

XEROX 8010 – 1981

To debut on computers, the mouse needed the first graphical interface, that of the Xerox 8010, which allowed interacting with the machine through images on the screen.

OSBORNE 1 – 1981

The era of micros had barely begun and the first portable computer, the Osborne 1, had already appeared. It weighed 12 kilos, had a 5-inch screen and fit in a small suitcase.

WORD – 1983

Bill Gates’ Microsoft launches Word Microsoft Office, the first program in the package that in a few years would monopolize the market for office programs

MACINTOSH – 1984

Apple launches the first computer with a mouse and graphical interface aimed at personal use, outside of companies. It was easy to use and included a drawing program

LASER PRINTER – 1984

First laser printer compatible with PCs, Laserjet begins to displace the dot matrix printers of the 70s and the inkjet printers, also of 1984

WINDOWS – 1985

The launch of Windows brings to the PC the advantages of the graphical interface popularized by Apple. Today, 90% of computers work with a version of this program

CD-ROM – 1985

The first CD-ROMs appear, new media with a capacity of 550 megabytes – 387 times the capacity of a 3 1/2 floppy disk, but only 12% of that of DVDs, released in 1996

DESKPRO 386 – 1986

Compaq launches the Deskpro 386, the first of IBM’s PC «clones» generation. Its 32-bit Intel processor was much faster than the competitor’s 16-bit processors

Internet – 1990

Since 1969, a network system called Arpanet was developed in parallel with computers. In 1990, with the creation of the HTML language, the Internet is officially inaugurated.

iPod – 2001

The music industry has been one of the hardest hit by the internet. iPod and other MP3 players open up the possibility of listening to sounds downloaded from the net anywhere

MICRO OF 100 DOLLARS – 2005

The challenge now is to democratize access to computers. With a simple structure, MIT proposes a micro that costs 100 dollars. But it’s still just a concept
