It is believed that the first computer was invented nearly 2000 years back. The first computer was known as abacus in which formulated constructs were used to program beads. During those days there were many historians who cautioned against the use of computer and waited until an understanding of computers was further given by a Frenchman in 1600s. This invention further paved way for the 19th century computers.
Various studies and researches were made on computers since then. England was supported by the government to produce a variation in existing form of computers. A mechanical calculator was introduced that was powered by steam and supported only a fixed program. These changes had undergone several variations until the automatic calculator came into existence. After using the calculator for long period, the idea of a punch card was conceived in the minds of bureau workers.
Later, during the World War II, a German engineer, Konrad Zuse invented the first freely programmable computer or the modern computer in 1941. This computer was earlier used only in the military areas to design new weapons with effective computer technology. This computer was also used as a precise and clear channel of information. After the invention of this modern computer, further inventions with better technology and features were in progress.
In the year 1947, the first computer with RAM (Random Access Memory) was designed to access important information in seconds. Further the invention of magnetic ore memory and transistor circuits was discovered in 1950s. This invention was a breakthrough for the advancement in computers. The computers with better memory space, features and functionality were further discovered and were confined to mathematically based operations like accounting, payroll and billing. These were only used in commercial places such as hospitals.
1980s is believed to be the true period for invention of today’s modern computers with all the features, functions and large memory space. Desk computers with the use of micro chips and compact disc came into existence. IBM was the first international brand to enter the history of computers. Thereafter, Apple and Intel also paved their way to advanced technology of computers. After IBM, Apple and Intel, Microsoft entered the computer industry with leading edge, evolving technology and competitive price
