What is analog computer?
An analog computer refers to a computer that uses the continuously changeable aspects of physical phenomena such as electrical, mechanical, or hydraulic quantities to model the problem being solved. In contrast, digital computers represent varying quantities symbolically, as their numerical values change.

An analog computer is any computer that represents its data in theform of continuously variable signals instead of the discontinuous encoded symbols used by digital computers.
I wont go into much detail but there is no such thing as an analogue computer per se; the only analog computer types are physical calculating devices not requiring electricity I.e an abacus. You could mean analog and digital connections the former using a fluid stream and the latter transfering in i…ndividual steps. Bottom line: if you want a computer, don't go looking for an analog one ( Full Answer )
There are many demerits of analogue computers. The main consinclude lack of versatility, and the fact that they are notabsolutely accurate among others.
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. ( Full Answer )

The first known analog computer is believed to have been built before 100 BC, it is unknown when it was invented.
Analog computers do not have memory like digital computers do, so this question has no answer as written. Analog computers have widely varying architectures, unlike modern digital computers which are all some variant of the stored program architecture first developed in the late 1940s. The most… common analog computing architecture from the 1920s through early 1980s and implemented both mechanically and electronically was the Integrating Analog Computer. On such computers the capacity was specified by the number of Integrators . A small computer might have 8 integrators while a large one might have 50 integrators. ( Full Answer )
A digital computer processes discrete data, an analog computer processes continuous data. . Discrete data (integers, character codes, boolean values, encoded floating point numbers, etc.) represent information with sharp discontinuities between represented values. Any data value not exactly e…ncoded must be approximated by one of the nearest encoded values. Operations on discrete values are more reliable and consistent, but usually slower with identical technologies. . Continuous data (voltages, currents, fluid pressure, fluid flow, shaft position, shaft rotation rate, etc.) represent information by analogy. All data values (within the limits of the machine) have an equivalent representation. Operations on continuous values are less reliable and less consistent, but usually faster with identical technologies. Analog computers are typically harder to program: they are either designed for one special purpose with the program permanently built in, or they must be "rewired" to reprogram them. ( Full Answer )
An analog computer does not use discrete steps, but smoothly models whatever is being calculated. Most are specialized devices, but the (good old) slide rule was a general purpose analog computer. It's one great advantage is speed, and high speed digital computers have mainly taken over.

The first analogue computing device was the human mind. Yes, it'strue; the human mind is an analog device.
A computer is considered digital because of the way that it stores information. The bit, which is a single "on" or "off" in a computer system, is a single digit. An example of a difference between digital and analogue is thus: If you have a voltage, from 0 to 5 volts, you could represent 2.5 volt…s in an analogue system as 2.5 volts. However, in a digital system, that voltage would need to be converted. The resolution refers to how many "steps" there are between 0 and 5 volts. Let's say that we were going to represent our voltage with 8 bits (or 8 on and off states). That gives us a potential for 256 combinations, with 0 being 0 volts, and 255 being 5 volts. Therefore, 2.5 volts would be represented by 128. That is a DIGITAL representation of an ANALOG value. ( Full Answer )
In principle, a computer could be either - analog computers have been made. But pretty much all computers in use today are digital.
A computer or computational device in which the problem variables are represented as continuous, varying physical quantities. An analog computer implements a model of the system being studied. The physical form of the analog may be functionally similar to that of the system, but more often the analo…gy is based solely upon the mathematical equivalence of the interdependence of the computer variables and the variables in the physical system.

An analogy for an animal cell with a computer might include thecomparison of the cell and a laptop. The case of the laptop wouldbe the cell walls, the Golgi body might be the programminglanguage, and the CPU could be the nucleus.
Some are, but most have been made obsolete by modern inexpensive high speed digital computers. The few that remain now are in specialized applications where speed and smooth transitions are more important than very accurate results. Even in those places digital computers called DSPs (Digital Signa…l Processors) are rapidly encroaching. ( Full Answer )
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.
Analog computers are also called continuous computers , as their representation of variables varies smoothly with no discontinuities during the computation. However they have less accuracy and a tendency to drift over time and with temperature. Digital computers represent their variables using co…ded symbols (typically but not always binary) and change values in a computation in discrete discontinuous jumps. However they can compute to high accuracy, don't drift, and can often detect and correct their own errors before they would affect a computation. ( Full Answer )

The Antikythera mechanism (pronounced /ËÃ¦ntÉªkÉªËÎ¸ÉªÉrÉ/ AN-ti-ki-THEER-É ), is conjectured to be an ancient mechanical computer   designed to calculate astronomical positions. It was recovered in 1900-01 from the Antikythera wreck,  but its complexity and s…ignificance were not understood until decades later. It is now thought to have been built about 150-100 BC. Technological artifacts of similar complexity did not reappear until the 14th century, when mechanical astronomical clocks appeared in Europe. ( Full Answer )

it can be small, it can be large. The critical question is how many integrators does your problem need?
None. Analog computers are "programmed" by wiring them up with cables and jumper wires. On some the program is even built in at design and cannot be changed.
The majority of modern computing devices are digital. That means they work by using many on and off type electrical signals. Analog computers work by using vary ranges of constantly-changing signals in real-time without converting them to digital sequences first.
The first known analog computer is the antikythera mechanism. It was found underwater in 1900. It is believed to have been made prior to 100BC. Inventor unknown.
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.

It not analog , its digital. Analog devices are continuous , digital devices have discontinuous states . As the only valid states of an abacus have each bead either up or down (never in the middle) it has discontinuous states and is digital.
depends, it can be as small as a Nordon bombsight or as large as one wall of a room. some have been smaller or bigger than that range.
Mechanical ones were built as far back as 100BC. The Bush Differential Analyzer was a large programmable electromechanical analog computer built starting in 1929. The famous Norden Bombsight of WW2 was an electromechanical analog computer designed in the 1930s and built through much of the 1950s, w…hen electronic analog computer bombsights replaced it. Electronic ones were built from the 1930s through the 1970s. ( Full Answer )
Mechanical and many electronic analog computers saved their output data as pen plots on paper. Some high speed electronic analog computers could read/write data as waveforms on multichannel wide magnetic tape (similar to the master recording tapes used in music studios). Such analog computers were… sometimes used as controllers and data collection devices on wind tunnels or in industrial process control before digital computers became affordable and reliable enough. These special tapes could be played back later off line at slow speed if pen plots on paper were desired. Other high speed electronic analog computers drew their output on CRTs which were then photographed to save it. There are other ways too. ( Full Answer )
The Antikythera mechanism is believed to be the earliest known mechanical analog "computer" by Derek J. de Solla Price. It was designed to calculate astronomical positions. It was discovered in 1901 in the Antikythera wreck off the Greek island of Antikythera, between Kythera and Crete, and has be…en dated to circa 100 BC. Devices of a level of complexity comparable to that of the Antikythera mechanism would not reappear until a thousand years later. ( Full Answer )

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.

He didn't. Charles Babbage designed and built the first analog computer in 1822, but the British government withdrew funding before the build was complete. Nevertheless, working models based upon Babbage's improved designs first appeared in 1855, a full 36 years before Vannevar Bush was born. A wo…rking model of Difference Engine No. 2 was built and completed in 1991, proving Babbage's original designs would have worked. Thus he is credited as the father of the computer. ( Full Answer )
It works on a constant supply of varying signals (and not necessarily even electrical). For instance, an automatic transmission in a car is pretty much an analog computer. As the pressure of the pump and the signals on the governor and modulator valve vary, the fluid goes through different valves in… the control body and controls which transmission bands are applied at what particular time. The more sophisticated of the mechanical clocks are also analog computers, as well as the old adding machines. Gears and tumblers had to make up for a lack of circuitry. ( Full Answer )
Because our brains lack the capability to de-code digital signals. Therefore, any digital sound must be converted to analogue (and be within a specific frequency range) for us to hear it.
Computers are discrete, finite machines. Analog information is continuous and infinite. Thus, computers cannot represent analog information directly; the analog information must be converted into a digitalform.
It is generally believed by scholars that Archimedes designed the first analogcomputer circa 100BC, an example of which was found over 100 yearsago. The device found, called the Antikythera Mechanism ,is a box of hand cut bronze gears that was used to performastronomical calculations.
The first official analog computer was created in 1912 by Arthur Pollen. The computer was designed for use with fire-control systems and ran off electricity.
Analog Computers use physical things such as mechanical, electrical and hydraulic aspects to model the real world. These include slide rules and nomographs.
No, a laptop is a kind of digital computer. Analogue computers used operational amplifiers in feedback loops tosimulate dynamic systems such as aircraft. They began to bereplaced by digital computers in the 1960s
Analog computers represent values as continuously variablesignals . This allows them to use any value within the rangepossible on the specific machine exactly, within the limits of themachine's component tolerances; however these signals are alsosusceptible to drift, temperature variation, componen…t aging,noise, etc. Once such errors occur there is no way to detect themand they continue to accumulate in the calculations. . Digital computers represent values as discrete encodedsymbols . This limits the values to those having valid codes, no value between two adjacent codes can be represented ;these codes are exact and if necessary there are ways to designsuch computers so that if a value does get corrupted duringprocessing or transfer between computers, the error can be detectedand the code corrected, restoring the correct value. Assuming that an analog computer and a digital computer are builtusing identical technology, the analog computer will always befaster than the digital computer. However current digital computersuse far more advanced technology than is now available for analogcomputers, as improvements on analog computer technologyeffectively stalled in the 1980s or early 1990s due mostly to thedevelopment of specialized microprocessors called digitalsignal processors (DSPs) a type of digital computer optimizedto perform digitally the kinds of tasks for which analog computershad previously been used. Both DSPs and standard general purposemicroprocessors are far easier to program (and if necessaryreprogram) than any analog computer (which often has to be entirelytaken apart and rebuilt to reprogram).
