Classification of Computer in sense of Technology  

1.        Analog Computer  (more Detail)
2.        Digital Computer
3.        Hybrid Computer
4.       Optical Computer

Qus -What is Analog?

It is a Current who go gic-jac way

Alternate Current, Analog Computer uses by Whether Science- tist(मौसम वैज्ञानिक) for measure Temperature(तापमान) & Pressure(दाब) etc.

Qus - What is Digital computer?

It works only on bit means (0 or 1).

Mostly computer are digital Computer

They are classified in sense of size

1.        Very Large (Super Computer)
2.        Large (Main Frame Computer)
3.        Medium (Mini Computer)
4.        Small (Micro Computer or PC)

Diode Work

Wheat stone Bridge

Note –

1. Convert analog signal to digital are called Modulation(modem)
2. Convert digital signal to analog are called D-Modulation(modem)
3. AC current boost by Transformer.
4. DC current boost by Booster or Amplifier.

Hybrid(मिक्स) Computer – It  is a mixture of Analog & Digital computer it uses in Nuclear fission(परमाणु शोध).

Optical Computer – It is Super high speed computer.

It is base on Light and quardru (sisa, lead, fiber)

Light speed = 3X10⁸ meter/sec =3X10⁵ Km/sec

Sun to earth light speed = 499sec

Light Year                       = Light speed in one year

                                                = 365X24X60X60X3X10⁵  Km/sec

                                                =9.46X10¹²  Km/sec
