What was the first computer used for for?

Answer 1

In electronic form, or in programatic form? A sundial could be thought of as a computing (measurement) system. Most of the early computers were really nothing more than control devices, or: systems that were designed to perform a specific and unique task. Computers can be classified by three major types: 1. Measurement Devices 2. Control Devices. 3. Logic Devices. Modern computers are a combination of several hundred (or even millions) of these systems, and unlike early computers - rarely use all of their systems functions or capabilities at the same time. Measurement devices, such as the most early clocks (Think of a grandfather clock, with weight suspended above an axis that provides power for the internal gearworks), are considered computer/measurement/tabulation devices because they do in fact count and report accurate readings (of time or the cycle of the moon). Control devices, such as "go or no-go" systems will take measurements and then perform an action. The "action" activity is what makes it a control device. Something either happens or does not happen when a pre-calibrated register is reconciled against an unknown measurement. You will find these systems in many quality control stations on factory lines. Logic devices - probably the most commonly thought of computer, is less of a calibrated machine and more like a traditional computer. A logic controlled device can make decisions and/or perform more than just one function. Algebra: If a=2 and c=4 then b must = 3 if sequence graduation <2 (As an example) - Computers that use logic can make decisions based on their input and any combination of measurement and control devices that are integrated with their framework. Computers that use logic go back several thousand years. They were not electro-mechanical however. The biggest difference between a catapult in 300 B.C. and a modern artillery piece is the fact that guidance and trajectory was calulated by a person instead of a computer - same math however, just performed more quickly. Same adjustments - just performed by integrated mechanical systems instead of a bunch of men adjusting ropes and chassis direction.
