The first thing that comes to mind when we talk about computer generations is that there are five of them, starting with the first generation, followed by four more generations like second generation,third generation of coumputer and forth generation, with the most recent fifth generation being the most technologically advanced. These generations began in the middle of the 1990s and continue today. After learning about these phases in the history of computers, everyone wonders what will happen after the fifth generation and how fifth generation computers will be categorised. Therefore, this essay will provide answers to all such questions.
The fifth generation of computers can be divided into groups based on when they were created, the operating system they used, and the materials they were made of, which helped to lower the size of the computer and stop it from generating additional heat. The primary types of these computers and some pertinent details about them are described below.
The Analogue Type Of Computer
An analogue computer is a type of computer that displays data as a variable in a continuous range of values. The earliest computers to emerge in the fifth generation were analogue ones. Real-time variables like voltage, pressure, and temperature are monitored using analogue computers. The analogue computers depict physically changing conditions continually. Compared to digital computers, analogue computers are less accurate. The slide rule serves as an illustration of an analogue computer that we may use to see what one looks like.
Since they can answer even the most complex equations with a signal travelling through the circuit at a speed close to that of light, analogue computers are often incredibly quick. A limitation of analogue computers is accuracy.
The Digital Type Of Computer
Different values are used by a digital computer with an internal display. All work is done in binary (ones and zeros). Due to its precision, digital computers are primarily used in households and offices. Although digital computers can solve equations with practically infinite precision, their speed lags behind analogue computers. Digital computers are much slower than analogue computers. Numerical methods are typically used to estimate complex equations. (binary). Additionally, hexadecimal values are used because they make solving complicated equations simpler than binary.
The Hybrid Type Of Computers
The digital unit of hybrid computers is utilised for solving control and logic equations, while the analogue component is typically solved using a differential equation solver. Accurate seed value is achieved by using an analogue front-end computer, which is then filled into a digital process of an iterative computer to get the final level of accuracy sought. With an extremely accurate numerical seed of three or four digits, the total number of digits required to attain the necessary accuracy is significantly reduced because precision requires fewer iterations.
