The history of computer development is often referred to in reference to the different generations of computing devices. Each generation of computer is. Information about Five Generation of Computer in PDF format. Useful for IBPS, SBI, UPSC, SSC and other competitive exams. The Generations of Computers. The development of computers started with mechanical and elec- tromechanical devices (17th devices (17 through 19th century).
Initially, the generation term was used to distinguish between varying hardware technologies. But nowadays, generation includes both hardware and software, which together make up an entire computer system. There are totally five computer generations known till date. Each generation has been discussedin detail along with their time period, characteristics. We've used approximate dates against each generations which are normally accepted.
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. In IBM introduced its first computer for the home user, and in Apple introduced the Macintosh.
Microprocessors also moved out of the realm of desktop computers and into many areas of life as more and more everyday products began to use microprocessors.
As these small computers became more powerful, they could be linked together to form networks, which eventually led to the development of the Internet.
Fourth generation computers also saw the development of GUIs, the mouse and handheld devices. Fifth Generation - Present and Beyond: Artificial Intelligence Fifth generation computing devices, based on artificial intelligence, are still in development, though there are some applications, such as voice recognition, that are being used today. The use of parallel processing and superconductors is helping to make artificial intelligence a reality.
Quantum computation and molecular and nanotechnology 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. It weighed over 30 tons and took up a lot of space, requiring a large room to house it. Second generation - The second generation of computers saw the use of transistors instead of vacuum tubes.
Transistors were widely used in computers from to Transistors were smaller than vacuum tubes and allowed computers to be smaller in size, faster in speed, and cheaper to build.
The first computer to use transistors was the TX-0 and was introduced in Third generation - The third generation of computers introduced the use of IC integrated circuits in computers. Using IC's in computers helped reduce the size of computers even more compared to second-generation computers, as well as make them faster.
They required manual assembling of components to form a functional unit and were assembly language dependent as compilers were developed to change from high-level language to assembly language program. They were low in cost, magnetic ferrite core memories were used as main memory and magnetic tapes as secondary memory. Improvement of the individual input and output memories helped to operate in parallel with the CPU.
They had the wide range of application in many fields like business to the engineering analysis and design. They were smaller in size, generates less amount of heat, computational speed was very fast i.
Only during this generation microprogramming, parallel processing, database management, multi-user application, automatic industrial control and much more were introduced.
