Analog computer : Numerical data are represented by measurable physical variables such as electrical voltage. E.g. Thermometer measures temperature of body like 38 degree celcius.(Numerical value) Digital computer : Digital computer accepts and process data in the form of numbers and all the character are converted into binary code. Binary code means 0 (zero) & 1 (one)“0” indicates “OFF”“1” indicates “ON” Hybrid computer : Hybrid computer used the combined feature of analog and digital machine. Hybrid Computer = Analog + Digital Hybrid computer used in geological departments. Microcomputer : Micro…
