  • Analog Computer
  • Digital Computer
  • Hybrid Computer

Analog Computer:

Analogue computers Are used mostly medical sciences. this very kind of computers Work on continuous Data value e.g.If you have to calculate the pressure or something similar Then kind of technology having will be useful.

Digital Computer:

Digital Computer is the most commonly Used Computer digital technique Which is widely Used and preferred Nowadays. this kind of computer microprocessor technology which is quite digital able to calculate and execute millions of instructions within a second. this also comes under kind of category as we can see downwards:

  4. Super Computer: The processor is biggest than other computers and processing capacity is highest than any other devices. it is a multiuser fastest calculating device, generally used in nuclear science for calculating purpose. CRAY-I is the first supercomputer India’s First Super Computer is PARAM-10000.

Hybrid Computer:

The kind of computer comes with both characteristics (digital and analogue) are called a hybrid. This is used there where it needs to calculate both the digital and analogue data for e.g. in hospitals.
