COMPUTER DEVELOPMENT FROM TIME TO TIME–Most of the activities that humans carry out in this modern season are carried out using computers. Especially during a pandemic / covid 19 like this, where all activities are transformed into completely online.
Computer equipment which was originally intended only as a means of supporting work, has now become a necessity that must be owned by the community.Before being equipped with sophisticated features like today, the development of computers began with a simple innovation that was born in the 1800s.
-The emergence of the first computer
The first computer was invented in 1822 by an English mathematician, Charles Babbage. Initially, Babbage intended to invent a steam-powered calculating machine that could calculate tables of numbers,The machine he later named “Difference Engine 0” and is predicted to be the world’s first computer. The form of Difference Engine 0 itself is very much different from most modern computer models today.
However, the working principle of this machine is the same as a modern computer, which is capable of calculating numbers or computing. Until 1890, an inventor named Herman Hollerith designed a card system that was able to calculate the results of the US census conducted in 1880. Thanks to this innovation, Hollerith managed to save the government budget of 5 million US dollars. Furthermore, Hollerith continued to develop his potential in the realm of technology until he finally succeeded in establishing the IBM computer company.
-The forerunner of the digital computer
The forerunner of the first digital computer was developed in 1930. It was Alan Turing who first developed the machine.
He is a successful mathematical researcher developing a machine that can execute a set of commands.
Thanks to his contributions, the machine was later given the name Turing machine, including a simulation of his ideas called the Turing test.
The first digital computer was developed by Konrad Zuse, a German mechanical engineer. Before the second world war broke out, Zuse built the first programmable digital computer called the Z1.
In 1936 in his parents’ living room in Berlin, he assembled metal plates, pins, and created a machine that could perform addition and subtraction calculations.
Although these early computer models were destroyed during World War II, Zuse is credited with creating the first digital computer.
During the second world war, in 1943, John Mauchly succeeded in creating a machine called the Electronic Numerical Integrator and Calculator (ENIAC).
ENIAC was originally created to assist the Army in predicting attacks.
ENIAC itself is equipped with analytical capabilities that can calculate thousands of problems in seconds. The ENIAC weighed up to 30 tons and required 457 square meters of space to house the machine.
This is due to the many supporting components that ENIAC has, such as 40 cabinets, 6,000 switches, and 18,000 vacuum tubes.
