The basic difference between analog and digital computers lies in the different approaches they take to handling data. Analog computers are able to deal with continuously varying inputs for complex phenomena such as voltage changes and temperature fluctuations. Digital computers must have their inputs reduced to a simple binary language in order to accurately model the world.Know More
Analog systems were once favored by engineers who lacked modern digital technology to run calculations on. As digital technology advanced, however, it came to be preferred for its higher precision and the flexibility of the programs that could be run on digital machines. Modern electronic computers are virtually all digital and express their models in terms of 1s and 0s.
Analog computers haven't died out, however. Oscilloscopes, of the kind used by electrical and sound engineers, are examples of analog computer technology. Slide rules are another example of a computation device that runs essentially on an analog input and output system. Perhaps the most ubiquitous example of an analog computer in the world is the brain itself. Brains are actually a combination of digital and analog systems. While the firing of a single neuron can be regarded as a simple on/off function, the communication between neurons is accomplished chemically by means of neurotransmitters that vary in concentration and intensity.Learn more about Computers & Hardware
According to the University of Mexico, serial ports transmit data one bit at a time, whereas parallel ports transmit 8 bits of data at a time. The location of the port depends on the age and type of the device.Full Answer >
Analog computers only work with continuous numerical data in analog quantities, digital computers can process both non-numerical and numerical data and a hybrid computer is a combination of both analog and digital. A hybrid computer has the accuracy of a digital computer paired with speed of an analog one.Full Answer >
The difference between analog and digital signals is that an analog signal is a continuous electrical message while digital is a series of values that represent information. Analog is conveyed by electrical current variations. Digital signals are relayed as a series of values that a device can read, such as a digital television.Full Answer >
The basic difference between coal and coke is that coal is the natural source and coke is the derivative product produced by destructive distillation. Both are used as fuel, but coke contains a higher carbon content and few impurities. Coke is also used during iron ore smelting as a reducing agent.Full Answer >
