Main Difference between analog and digital computer
There are two types of computers that are known as analog and digital computers. Both types of machines have their own uses and misuses, but digital computers have taken over from analog ones. Analog computers were used in abundance a few years ago, but now their number has decreased thanks to the advent of digital computers. Their differences will be discussed in detail during this topic. Both types of networks are used to transmit information with the help of electrical signals, but differ in the way the information is transferred. In analog computers, data is sent with the support of continuous signals, while in digital computers data is transmitted with the help of discrete signals that are generally in the form of binary numbers. The difference can be further explained because analog computers are less accurate compared to digital computers. Results from analog computers can have some percentage error, while results from computers can be up to 100% accurate. Analog computers are used for quantities for which exact values are not always necessary, such as temperature and speed, while digital computers are used for numbers that require exact values, for example calculations that are performed during construction of a bridge and other operations. The best example of an analog device will be the oscilloscope, which engineers still use to take measurements. While the best case of digital devices will be a pedometer that gives the exact number of steps. Analog computers are slower and less reliable, while digital computers are high-speed devices that can be trusted. Digital computers are used all over the world, while analog computers have been restricted to specific fields such as medicine and engineering. A more detailed explanation of both types of PC is provided in the following paragraphs.

What are analog computers?
Analog computers can be a very broad field to define. In simple words, a computer that uses the continuous signal for its operation is called an analog computer. Due to this type of indicator, they can receive inputs and produce results regularly, and this helps to solve complicated processes. No matter how strong the signal is and even if it is in electrical or mechanical form, analog computers are capable of handling it. The emphasis in this type of computer is on getting a fix, however it can be error prone. Analog computers began in the 19th century.century and have advanced over the years. Before the origin of digital computers, they were considered the best forms of devices. An example of an analog computer would be a mercury thermometer that calculates the temperature of the human body and then displays it as a mercury range. Because you have noise in your system that also affects the results, while the storage process in analog devices is complicated, as they can contain values, but that is only possible for a certain period of time.
What are digital computers?
Digital computers are defined as devices that use the discrete signal for their processes that are in binary form. In digital computers, input is encoded as zeros and ones for a more accurate result. An example of a digital computer will be a calculator in which all the coding is already done, and you get a correct result that is not possible in the case of analog devices. This is also because e is the minimum noise in the system because the incoming electrical noise is in the form of an analog signal. The calculations, in this case, take less time because all the coding is already done and the scrolling results can be as accurate as possible. Digital devices have taken over the analog ones in recent times due to their effectiveness. It is more reliable, has more space and can store data for longer, although its cost is higher. The most advantageous factor is that there are no observatory errors since all calculations are performed by the computer and the values are displayed correctly.
