A digital device is an electronic device which uses discrete, numerable data and processes for all its operations. The alternative type of device is analog, which uses continuous data and processes for any operations. Any device which uses a computer of any sort in its operations is at least partially digital.Know More
An ever-growing number of devices use digital technology, despite the fact that the world itself is largely analog in nature. For instance, if a dog jumps, it could jump a yard, just a foot, or literally any fraction of the distance between. If the world were digital, there would be some minimal unit, say, a sixteenth of an inch, which would be the minimum amount moved, and any movement would be some multiple of a sixteenth of an inch. In the same way, any product of a digital device will fall into one of a set number of possibilities, although these possibilities are often so numerous a human could not tell the difference.
Another example is the vinyl record compared to the compact disc. A vinyl record is an analog recording device. It records sound at exactly the time it is detected. A CD, on the other hand, records sound at the best approximation of the time it's detected that's allowed by its discrete storage units. While in some ways less precise, such recording is far more compact and, in most cases, is undetectable by humans.Learn more about Inventions
For human beings, true flight is possible only with the aid of mechanical devices. These include balloons, airships, airplanes and helicopters. Human-powered flying machines are possible but difficult to make practical because of the high power-to-weight ratio required to make powered flight possible.Full Answer >
Labor-saving devices are inventions that reduce the time and effort needed to perform or complete a task. Farm equipment, home appliances and construction equipment are examples of mechanical inventions that save time and physical labor.Full Answer >
While devices to measure time have existed for thousands of years, the first mechanical clock was created in 725 by Yi Xing and Liang Lingzan in China. This was the first clock to use an escapement mechanism rather than relying on the flow of water to measure time.Full Answer >
