Different between Analog and Digital computers:

    

      The different between analog and Digital computers is as follow:

                            Analog computers:

1.      It provides us continuous value.
2.      It represents physical quantities in the form of waves or in a continuous form.
3.      It has no state.
4.      It is difficult to use.
5.      It has low memory.
6.      It has slow speed.
7.      It is used in engineering and science.
8.      It is less reliable.

                          Digital computers:

1.      It provides us discrete value.
2.      It represents physical quantities with the help of symbols or number.
3.      It has two states ON (1) OFF (0).
4.      These computers are easy to use.
5.      These computers have big memory.
6.      These computers have fast speed.
7.      It is used in all field of life.

      8.         It is more reliable.
