History of Computers
The word computer was first used in 1613, it is a person that carries out calculations, or computations, and the kept continuing with the same meaning until the 20th century. The history of modern computer began with two separated technologies with automatic calculation and programmability ,some devices can be worth mentioning though, kinda like some mechanical aids from computing, which was very successful and has been around for centuries until the electronic calculator, it's like the abacus, it was made around 2500 BC. In 1642, the Renaissance saw that the invention of the mechanical calculator, a device that can perform mathematical problems without relying on human intelligence. The calculator was at the root of development of the computers in to separated forms. Basically it was in trying to make more powerful flexible calculators.
The portrait of Jacquard was sewed on silk on a Jacquard loom and it needed it about 24,000 punched cards to make (1839).
It inspired him to use perforated cards in his engine. It's the fusion of the automatic calculation with programs that has produced the first recognizable computers. In 1837, Charles Babbage was the first to design a fully functional computer.
Then in the late 1880s. Herman Hollerith invented the recording of data on a readable machine. Earlier uses of the machine has been mostly for control, not data. After some trials with paper tape, he then settled on some punched cards. Then to process the punched cards he invented a processing industry. During the first half of the 20th century a lot of scientific computing needs then were met by increasingly complicated analog computers. Which was used a direct or electrical model of the problem as the basis for computation. But the computers were not programmable and it lacked accuracy of the...
