When we study about the generations of computers which are classified as the five generations staring from 1st to 5th on the basis of the innovations in their technology, time and advancements. These generations started from the early nineties to the end of the nineties. After studying about these eras of evolution of computer a question rises in every mind that what happened after the fifth generation and what is the classification of fifth generation computers? So all such questions will be answered in this article.
The fifth generation of computers could be classified into to many types on the basis of their time in which they were introduced to the world, on the basis of the technology they used to process the input into the required output and the type of material that was used in their physical structure which help them in the reduction of their size and reduced the production of heat. Some of the most basic types of these computers are listed below along with important information about them.
The Analogue type of Computers
An analogue computer is a sort of computer that shows data in a continuous set of values as a variable. Analog computers were the earliest. Analog computers are employed in the monitoring of real time, such as temperature, pressure and voltage constantly varying data. Analog computers may not be as versatile as digital computers but usually less accurate. If we want to see the example of an analogue computer then we must observe the slide rule as an example for such computers.
Analog computers are usually extremely quick as they can resolve most complicated equations with a signal flowing through the circuit, which usually is a significant portion of the light speed. The accuracy of analogue computers, on the other hand, is not good; they are restricted to three or at most four precise numbers.
The Digital type of Computers
An internally displayed digital computer utilizes different values. The numbers zeros and ones are used for all information. Digital computers are the computers we use in our homes and workplaces. Digital computers may be developed to virtually limitless precision in the solution of equations, but very slowly in comparison with analogue computers. Complex equations are generally estimated with iterative numerical methods, which take large amounts of iterations according to how well the first “assumption” at the final result is and what accuracy is required.
The Hybrid type of Computers
Hybrid computers are computers with both analogue and digital computing capabilities. The digital component usually works as a control and logical operation, whereas a differential equation solver is generally used for the analogue component. The usage of analogue front-end computer, which is subsequently filled into the digital process of an iterative computer to reach the ultimate desired level of accuracy, is used to generate a very good but somewhat inaccurate ‘seed’ value. The total number of digits needed to achieve the requisite accuracy is substantially decreased with a very precise numerical seed of three or four digits, as fewer iterations are necessary.
