First generation
The first computers used vacuum tubes to circuits and magnetic memory drums, and were often enormous, occupied entire rooms. Its operation was very expensive and besides consume much electricity, generated much heat, often causing malfunctions. First generation computers were based on the language of machine, the programming language of lower level that computers understand, for operations, and could only solve a problem at the same time. -
Second generation
Transistors replaced vacuum tubes and marked the beginning of the second generation of computers. The transistor was invented in 1947, but did not have widespread use. The transistor was far superior to the vacuum tube, allowing computers become smaller, faster, cheaper, more efficient energy and more reliable than their first generation predecessors although transistor still generated a great amount of heat which damaged the computer, was a great improvement over the vacuum tube. -
Third generation
The development of the integrated circuit was the hallmark of the third generation of computers. Transistors were miniaturized and placed on silicon chips, called semiconductors, which dramatically increased the speed and efficiency of computers. Instead of punch cards and prints, users they interacted with third generation computers via keyboards and monitors and interacted with an operating system -
Fourth generation
The microprocessor brought the fourth generation of computers, since thousands of integrated circuits were built on a single chip of Silicon. In the first generation filled an entire room now could fit in the Palm of the hand. The Intel 4004 chip, developed in 1971, placed all the components of the computer, from the central processing unit and memory to input controls / exit, on a single chip. -
Fifth generation
Devices fifth generation computer, based on artificial intelligence, are still in development, although there are some applications, such as voice recognition, currently being used. The use of parallel processing and the super-conductive is helping to realize artificial intelligence. Quantum computing and molecular nanotechnology will change radically the face of computers in the next few years.
