Digital
- Advantages
- exact reproducible results of calculation
- insensitive to drift, component aging, temperature, etc.
- Disadvantages
- all data encoded to nearest representable value
- slow and expensive when implemented with same technology as analog computer
Analog
- Advantages
- continuous representation of all data within the range of the machine
- fast and inexpensive when implemented with same technology as digital computer
- Disadvantages
- results of calculations may not be reproducible due to undetectable setup errors
- sensitive to drift, component aging, temperature, etc.

∙ 11y agoBecause analog computers do not have to encode and decode from binary, and instead use the physical properties of electricity directly, the functions they can perform are done at a substantial fraction of the speed of light, and are therefore dramatically faster than what even the most powerful supercomputer is capable of. Calculations that are very difficult for a digital computer can be done with great speed by an electric analog computer. == == The problems with analog computers stem from the same electrical phenomenon upon which the computer is based. Just as a digital computer is slower because it has to work in and out of binary code to accomplish anything, analog computers are subject to electrical problems and limitations such as the noise floor of its signals, the finite nature of an electron's charge, microelectronic parasitic effects, temperature issues and non-linearities. It is simplest to look at electric analog computing as an improvement on past analog forms, but still suffering from problems analogous to hydraulic and mechanical computing. Hence digital computers are useful over wider ranges of problem types.

Are most computers analog machines?
No, most computers today are digital machines. Digital computers operate using discrete binary data, represented as 0s and 1s. Analog computers, on the other hand, manipulate continuous physical quantities such as voltage, current, or mechanical motion. While analog computers were used in the past, the vast majority of computers in use today are digital.
How a digital computer work.how can we define a digital computer and analog cmputer?
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.
Which is faster an analog computer or a digital computer?
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.
What are the characteristics of digital analog and hybrid computers?
• 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.
When was computer made?
Analog computers were first made in the late 1920s, Digital computers were first made in the early 1940s.
What do electronic computer manufacturers produce?
Included in this industry are digital computers, analog computers, and hybrid digital/analog computers.
What are the disadvantages of having an analog watch?
The advantages of an analog watch over a digital watch are that analog watches can be more durable in some facets, than a digital one. Many watch enthusiasts also feel that analog watches are more aesthetically pleasing than digital watches.

What is the answer for a question 'how do you do'?
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.
What is the difference between digital computers and hybrid computers?
Digital computers are purely digital, i.e. they use digital(electronic) means to process data. Hybrid computers conversely use both digital and analog technologies.
How do you answer for the question What is a hybrid computer?
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.
What are basic elements of digital signal processing?
The basic elements in digital signal processing are an analog to digital converter, digital signal processor, and digital to analog converter. This process can take an analog input signal, convert it to digital for processing and offer an analog output.
