  • 2. Types of computer Digital Analog Hybrid computer computer computer Main frame Super Micro Mini computer computer computer computerHome PC
  • 3. Analog computers measures and answers thequestions by the method of “HOW MUCH “.•Signals are continuous of (0 to 10V)•Accuracy 1% approximately•High speed•Output is continuous.•Time is wasted in transmission time
  • 4. Analog computers
  • 5. Digital computersDigital computers counts and answers the questions by the method of HOW MANY. The input data is represented by a number. These are used for logical and arithmetic operations. Signals are of two levels (0V or 5v) Accuracy unlimited Low speed sequential as well as parallel processing Output is continuous but obtain when computation is completed
