Abak (computer, Latin Abacus) is a plate-shaped tool for easier computational operations. First useful in Asia.

In Europe, Roman abacus was occasionally used until the 16th century

Pascalina is a mechanical machine that could collect and subtract large numbers. It was designed by Blaise Pascal in 1642 to facilitate the work of his taxman father. Pascalina was able to work with numbers up to 9,999,999. Work on the machine was started by Pascal in 1642, who was not even 19 years old at the time. It was the first such machine after the calculating machine made by Wilhelm Schickard in 1623.

The word "computer" was first recorded as being used in 1613 and originally was used to describe a human who performed calculations or computations. The definition of a computer remained the same until the end of the 19th century, when the industrial revolution gave rise to machines whose primary purpose was calculating.

The analytical machine was created as an extension of the ideas that Charles Babbage had tested in the differential machine, with the analytic machine being programmable. The analytical machine had all the features of modern computers, including:

binary system → every computer today uses such a numerical system, which consists only of units and zeros.
input / output unit → unit for writing data to the computer and for printing results (printer)
storage unit → Charles Babbage envisioned using punched cards for his computer, which was later used to store data until magnetic recording was discovered.
central processing unit → the unit that will perform the data processing
programming language → analytical machine had a set of commands that managed data and central unit functions.

These were partially programmable digital electronic computers, and their primary building unit was an electronic tube. Data entry was via punched paper tape. Colossus' chief architect was Tommy Flowers, who worked at the UK Post Office on development. The existence of these computers was secret until the 1970s.

Apple I was the first computer developed by Steve Wozniak in 1976 and manufactured by the American company Apple.

It used a television set as a monitor, had a basic routine in a ROM powered by a computer at power-on, while a cassette player interface was used to store and load data. The tape read and write speed was 1200 bit / s. The Apple I was simply a computer on par with the KIM-1.

A total of 200 Apple I were assembled.

The Atari 2600, originally branded as the Atari Video Computer System or Atari VCS for short until November 1982, is a home video game console from Atari, Inc.
