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.
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 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.

Included in this industry are digital computers, analog computers, and hybrid digital/analog computers.
Computers are designed according to the data they are supposed to process. In this regard there are three types of computers Analogue, Digital and Hybrid.
That is it. All known computers can be put in one of those categories. Some may argue that a neural net computer (like the human brain) defines a fourth type of computer, but even that really is a hybrid.
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.
The unique name for the combination of analog and digital computers is "hybrid computer." Hybrid computers leverage the advantages of both types, using analog components for real-time processing and digital components for data storage and complex calculations. This combination allows for enhanced performance in specific applications, such as simulations and control systems.

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.
