Evolution And History Of Computers – Tech Tribune France

The computers we see today were not always the same. By computers, I mean anything capable or useful in computing. The first computers were mechanical calculators, punch machines, etc. Then came the ENIAC, etc., which was calculated numerically but was too big. Using personal computers started as a hobby among a certain group of people and has become something that people cannot live without.

As I write about computer advancements, I see that the computers of the future will be more mobile and more powerful than desktops and laptops, including the one I use to compile the history of computing in the form of a presentation. Check out the advancements in the IT field in PPT form below. The link to the progress of the computers PDF file is given towards the end of the post.

Presentation transcript: key points

Anything that helps calculate anything is a computer. The first computers were essentially calculators with or without storage capacity. This presentation is about advances in computers.

1]The first computers were mechanical

2]The Night-Time Machine was developed by Leonardo Da Vinci to guess the time at night when it was dark. During the day, they measured time using the shadow. Clocks are also computers that calculate time using voltage or crystal ticks.

3]1935: Odhner Circa is developed. It was among the first computers used by mathematicians.

4]1820: The arithmometer was developed for clerks for addition tasks

5]1889: Felt’s Comptometer or Comptograph was one of the first calculators/computers capable of performing mathematical operations while being able to print. However, it could not store data.

6]1904: The Burroughs company invents and sells the Burroughs calculator which can perform arithmetic operations. It was popular among clerks due to its size.

7]1910: Burroughs creates an additional machine and calls it Adding Machine. This model could store data in the machine itself.

8]Around 1890, while others were concentrating on calculating machines, Hermann Hollerith was busy creating punched cards for use with his tabulating machine and sorting box. The concept of the machine was to perform functions using the blocking and passing of the electrical system. Electric needles ran over the punched cards. When they encountered gaps (hole), the circuit was complete and created a binary one. It was one of the first machines to calculate massive amounts of data in a fraction of a second and was probably the main one for binary operations in computers.

9]A book on Hermann’s Tabulating Machine is available as Origins of Digital Computing.

10]The first real computer was the ENIAC: it could perform arithmetic operations and also be able to perform general tasks. However, it was too big and not intended for the general public. It was developed around 1945

12]In 1959, IBM 1970 was developed. This machine was able to store data in the computer. It also marked the transition of computers from vacuum tubes to transistors.

13]The real revolution in computers was the MITS Altair 8800, designed in 1974. Besides hobbyists, it was purchased by organizations to speed up their accounting.

14]The IBM 8086 brings us up to date with modern computers. It is an obsolete model with CPU and a large monitor but worked on complex transistors and ALUs. These types of models were called desktop computers because they were kept on desks and used a keyboard and mouse to operate them. Input to these computers was binary signals sent by the keyboard (ASCII characters) and mouse (screen coordinates). If you have programmed in MS BASIC, you can easily understand how these input devices work.

15]Desktop computers were further reduced as technology advanced. Desktop computers are being replaced by laptops in many organizations. Individuals also prefer laptops because they are smaller and can be carried anywhere. The Microsoft Windows operating system has become very popular.

The future of computing is convertible computers and tablets. The only need of the hour is to pack powerful computing resources into a much smaller tablet and keep it running, a battery that can last a long time.
