Analog computers are also called continuous computers, as there are no discontinuities in their computations. A mechanical analog computer might represent variables by rotation rate of shafts, any given shaft can rotate at any speed and will smoothly accelerate or decelerate its rotation as the calculation proceeds. An electronic analog computer might represent variables by voltages, say any voltage between -20VDC and +20VDC with voltages smoothly varying as the calculation proceeds.
Digital computers on the other hand have discontinuous states that they jump from one to another.
Hybrid computers are simply computer systems that combine both analog and digital computers together. Usually the digital computer controls the analog computer, reconfiguring it and entering new data each time the analog computer completes one problem, to have it solve a different one.
Because the first, second, and third generation computers were also digital 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.
Digital computers work with exact discretely coded representations of numbers.Analog computers work with approximate continuous representations of numbers.Hybrid computers are computers that are part digital part analog.I have used all three types, each has advantages.
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.
• digital computers work on discrete data representing quantities by encoding (e.g. integers, coded alphanumeric characters, coded floatingpoint numbers). • analog computers work on continuous data representing quantities by analogy (e.g. voltages, currents, shaft rotation rate, shaft position). • hybrid computers are a combination of digital & analog computers connected together to work as one machine.
Digital computers are purely digital, i.e. they use digital(electronic) means to process data. Hybrid computers conversely use both digital and analog technologies.

what is the difference between digital sound and digitized sound
The difference between computer engineering and digital electronics is that digital electronics represents signals. Computer engineering integrates several fields of computer science and electrical engineering to make computer systems. Digital electronics is the field of computers and computer controlled devices including the ones with analog inputs and outputs.
A digital screen is a liquid crystal display (LCD) type that exhibits characters such as numbers or letters. Portable computers and digital watches are examples of this.
what is difference between compact discs and digital versalite discs
d. Modem It modulates digital signals to analogue signals and demodulates analogue signals back to digital signals.
The difference between digital boxes and digital adapters is that digital boxes can offer extra services such as Pay Per View, On Demand and Premium Channels such as HBO.
All computers are digital. *Analogue
The capacity is the difference between a laptop and a personal digital assistant. Personal digital assistance can't carry out all the functions that a laptop can do.
There is no such difference. All digital computers have elements that basically work with two different states; these are commonly called 1s and 0s, sometimes "true"and "false". But there is no difference in this sense between IBM and Apple.
