Computer History

1st Generation

The first computers used vacuum tubes for circuitry magnetic drums and for memory and were often enormous, taking up entire rooms. They were very expensive to use and use a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions.

2nd Generaton

Transistors replaced vacuum tubes in the second generation of computers. The transistor was invented 1947 but did not see widespread use I but did not see widespread use in computers until the late 1950s.The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessors.

3rd Generaton

The development of the integrated circuit was the hallmark of the third generation of computers. Transistors were miniaturized and placed silicon chips , called semi conductors, which drastically increased the speed and efficiency of computers.

4th Generation

the microprocessor brought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip. What in the first generation filled an entire room could now fit in the palm of the hand. The Intel 4004 chip, developed in 1971, located all the components of the computer from the central processing unit and memory to input/output controls on a single chip.

5th Generation

Fifth generation computing devices, based on artificial intelegance , are still in development though there are some applications sutch as,voice recognition that are being used today the use of parallel processing and superconductors

are helping to make artaficcial intelligence a reality. quantum computalation and molecular and nanotechnolagey will radically change the face of computers in years to come. The goal of fifth-generation computing is to develop devices that respond to natural language input and are capable of learning and self-organization.

Alan Turing

Alan Turning's full name is Alan Mathison Turing he was born on the 23rd of June 1912 but sadly he died on the 7th June 1954 he was a British pioneering computer scientist mathematishion logical cryptanalyst and theological biologist . he was highly influential in the development of computer science providing a
