Analog Computer - Real Computers
... Computer theorists often refer to idealized analog computers as real computers (because they operate on the set of real numbers) ... Digital computers, by contrast, must first quantize the signal into a finite number of values, and so can only work with the rational number set (or, with an approximation of irrational numbers) ... These idealized analog computers may in theory solve problems that are intractable on digital computers however as mentioned, in reality, analog computers are far from ...
History Of Computing - Early Computation
... This was the first known computer and most advanced system of calculation known to date - preceding Greek methods by 2,000 years ... gear, which was later used in analog computers ... mechanism is believed to be the earliest known mechanical analog computer ...
Hybrid Computer
... Hybrid computers are computers that exhibit features of analog computers and digital computers ... component normally serves as the controller and provides logical operations, while the analog component normally serves as a solver of differential equations ... In general, analog computers are extraordinarily fast, since they can solve most complex equations at the rate at which a signal traverses the circuit, which is ...
Packet Switch Stream
... After a period of pre-operational testing with customers (mainly UK universities and computer manufacturers at this early phase) the service was launched as a commercial service on 20 August 1981 ... X.25 interface, via a dedicated four-wire telephone circuit using a PSS analog modem and later on, when problems of 10-100ms transmission failures with the PCM Voice based transmission equipment used by. 1980s era installation lead times for suitable 4-wire analog lines could be more than 6 months in the UK ...
Pascal's Calculator - History - Precursors - Analog Computers, Automatons
... They belong to a group of mechanical analog computers which, once set, are only modified by the continuous and repeated action of their actuators (crank handle, weight ...
