Computers DO use analogue methods to transfer information.
Modems, for example (short for "Modulator/DEModulator") use either frequency shift or phase shift to transmit information.
Your monitor, even if it is a digital monitor, is using light to transmit information to your eyes, which is an analogue medium.
Even your wireless connection uses frequencies (analogue) representing ones and zeros to your computer; where the frequencies are converted back to ones and zeros by the wireless card.
analog computers,continuous quantities are used. computation are carried out physical quantities such as voltage,length,current,temperature etc. the devices that measure such quantities are analog devices example voltmeter,ammeter.hybrid computer the best qualities of both the digital and analog computer. hybrid computers are best used in hospital. hybrid computers are also used in wheather forecasting.
Ans. Difference between a digital and hybrid computer:Digital Computers:These are general purpose computers. They accept data in the form of discrete digits (0 and 1). They have large storage capacity. They come in many sizes and shapes. They are generally used in every field of life. They are slow but accurate as compared to analog computers.Hybrid Computers:Hybrid computers combine best features of analog and digital computers i.e. speed, accuracy reliability etc. They are special purpose computers, which are fast and accurate. Hybrid computers help the user to handle both analog and digital type of data.SHOAIBBILALShoaibbilal64@yahoo.com
Digital quantized information and analog is just information. Like the letter "i" on your screen is digital and made up of a few pixels= quantized. The letter "i" drawn on a piece of paper is not quantized = analog.
No. Just like an analog (wired, non-powered) phone, the ECG or Electrocardiograph simply amplifies the electrical impulses it receives from sensors (electrodes on the skin), which are polarized when the heart beats. It is analog because it never converts information into ones and zeroes. However, it is not a computer because it doesn't compute, or process the information, it just displays or prints it. Now, however, many ECGs are attached to computers which analyze the data it receives, though the computer is attached to the analog ECG input and has to convert that to digital data to process it.
All computers are digital. *Analogue
Included in this industry are digital computers, analog computers, and hybrid digital/analog computers.
At this time, no, most computers are digital. However from the 1930s through the 1960s analog computers probably did outnumber digital computers as they were generally smaller and less expensive than digital computers.

Hybrid computers are computers that exhibit features of analog computers and digital computers. The digital component normally serves as the controller and provides logical operations, while the analog component normally serves as a solver of differential equations.
built with the same level of technology, analog computers are always faster but less accurate than digital computers. however as little significant work on analog computers has been done since the 1980s, they currently significantly lag behind digital computers in speed.
abacus old-fashioned cash register (with gears and handle) gear-driven clocks/watches ---- Actually the above are examples of mechanical computers, not analog computers. Analog computers use continually variable quantities. An abacus uses discrete units of measurement and is digital, though not binary. A slide rule is an example of a simple mechanical analog computer. Another example is the Norden Bomb Sight. An ancient example is the astrolabe. More complex analog computers are programmable and can use fluid, mechanical, or electronically set values. There is a link below to an article on analog computers.
