Based on the operating principles, computers are classified into types. They are
1. DIGITAL computers
2. ANALOG computers
3. HYBRID computers

1. Digital computers

2. Analog Computers 91AACATJSFC9CA9M781NCAF7O2LDCA9YN0TQCACITEEJCA4JU11ICA3UPK3KCAK9MPOHCAKQCGWOCAAXM0Y1CA04QLZ1CAC9L.jpg
            Analog computers operate by measuring rather than by counting. These are the computers, which work on discrete data or physical quantities like speed, pressure, temperature, voltage etc.

3. Hybrid Computers

Here it measures first and then it converts into numbers. It is used in scientific and medical applications.
