When we discuss the generation of computers, the first thing that comes to our mind is that there are five generations of computers, which started with the first generation, followed by four more generations, making the latest fifth generation the most advanced. These generations started from the mid nineties to the present time. After studying about these eras of the evolution of computers, a question rises in everyone’s mind: what will happen after the fifth generation and what is the classification of fifth generation computers? So all such questions will be answered in this article.
Fifth generation computers can be categorized on the basis of when they were produced, on the technology their operating system used, and the material that was used in their production, which helped them to reduce the size of the computer and prevent it from producing more heat. Some of the basic types of these computers are listed below, along with important information about them.
The analogue type of computer
An analogue computer is a sort of computer that shows data in a continuous set of values as a variable. Analog computers were the first ones to develop in the fifth generation. Analog computers are employed in the monitoring of real-time variables such as temperature, pressure, and voltage. The analogue computers represent continuously varying physical properties. Analog computers are less accurate than digital computers. If we want to see an example of an analogue computer, then we must observe the slide rule as an example of such a computer.
Analog computers are usually extremely fast as they can solve the most complicated equations with a signal flowing through the circuit, which is a considerable portion of light speed. Accuracy is a drawback of analogue computers; they are restricted to at most three or four precise numbers.
The digital type of computer
An internally displayed digital computer utilises different values. It uses binary (ones and zeros) for all types of work. Digital computers are mostly used in our homes and work places due to their accuracy. Digital computers may be developed to virtually limitless precision in the solution of equations, but their drawback to analogue computers is their speed. Analogue computers are far more fast than digital computers. Complex equations are generally estimated with numerical methods (binary). It also uses hexadecimal values as it is easier to solve larger equations with hexadecimal than with binary.
The Hybrid type of computers
Hybrid computers consist both analogue and digital computing capabilities, for control and logic equations digital unit is used, 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 achieve inaccurate seed value. The total number of digits required to achieve the requisite accuracy is substantially decreased with a very precise numerical seed of three or four digits, as fewer iterations are necessary for accuracy.
