The history of computer hardware development is a constant record of the trend towards making computers faster, cheaper and more able to store data. Before the multipurpose computer existed, man performed most of the calculations himself, until the calculus appeared to assist in calculations. The calculators are still developing, but the computer has an added advantage of it, which is multi-use, not just for counting numbers. Computer hardware has undergone significant developments since the 1940s, becoming the basis for many other uses other than arithmetic such as automation, communication, control and education.
There are examples of primitive calculators that represent the earliest ancestors of the computer, including the abacus and antiquity mechanism, an ancient Greek device that was used to calculate planetary movements and dating since 87 BC. Almost. The end of the Middle Ages saw European activity in the science of mathematics and engineering Wilhelm Schickard was the first of a number of European scientists to create a mechanical calculator. Without the abacus as a primitive computer because it was like a calculator in the past. In 1801, Joseph Marie Jacquard improved the existing nouveau forms, using a series of sequential paper cards as a program for weaving complex forms. The result was that Knoll was not considered a real computer but was an important step in the development of modern digital computers. Charles Babbage was the first to design and design a fully programmed computer at the beginning of 1820 but due to a combination of technical limitations at the time and financial limitations, as well as the inability to solve the problem of poor repair in his design, the device was not actually built in his life. A number of technologies that later proved useful in computing, such as the perforated card and the valve tube, appeared at the end of the 19th century, and automatic data processing with large gradient using punch cards was created using scheduling machines designed by Hermann Hollerith
The success of powerful and convenient computers began in the 1930s and 1940s, and the main features of modern computers such as the use of digital electronics (most of which were invented by Claude Shannon in 1937) and the ability to program more smoothly were gradually added. Setting one point during this journey as "the first digital computer" is very difficult.
A basic achievement was the Atanasoff-Berry 1937, a custom-purpose machine that used valve-driven computing, binary numbers, and memory. The secret British Colossus (1944), which had limited programmability but introduced a device that used thousands of valves, could be trusted and reprogrammed electronically. Harvard Mark I 1944 A high-grade electromechanical computer with limited programmability.
The American computer based on the decimal system (1946-Enyak) was the first general purpose electronic computer but basically its structure is not smooth, which means that reprogramming essentially requires reconnection. The Konrad Süze Z machines, together with the Z3 (1941) electromechanical machine, are the first working machine to offer the automatic calculation of binary numbers and the ability to program in a practical and convenient manner.
The team that developed ENIAC realized its hardware flaws and came up with a more flexible design that became known as the von Neumann architecture (or "stored software structure"). Stored program architecture became by default the basis of all modern computers. A number of projects began to develop a computer based on the structure of the program stored in the mid to late 1940s. The first computer was completed in Britain. The first, best-known, was the Small-Scale Experimental Machine, but EDSAC was perhaps the first practical version to be developed.
LED-based computer designs became in use during the 1950s, but over time they were replaced by transistors as they were smaller, faster, cheaper and more reliable, all of which allowed them to be produced at the commercial level in the 1960s. In the 1970s, the choice of integrated circuit technology helped produce computers at a low cost to allow individuals to own a personal computer of the currently known species
