Question

Digital or binary logic has fascinated many people over the years. The very idea that a two-valued number system can possibly be the basis for the most powerful and sophisticated computers seems astounding, to say the least.

One essential reason for basing logical operations on the binary number system is that it is easy to design simple, stable electronic circuits that can switch back and forth between two clearly-defined states, with no ambiguity attached. It is also readily possible to design and build circuits that will remain indefinitely in one state unless and until they are deliberately switched to the other state. This makes it possible to construct a machine (the computer) which can remember sequences of events and adjust its behavior accordingly.

Digital logic may be divided into two classes: combinational logic, in which the logical outputs are determined by the logical function being performed and the logical input states at that particular moment; and sequential logic, in which the outputs also depend on the prior states of those outputs. Both classes of logic are used extensively in all digital computers.

Since both types of logic circuits begin with logic gates to combine logical input signals in various ways to produce the desired outputs, we will begin on this chapter by seeing how the basic logic gates work.

Explanation / Answer

Advantages of Binary System

1) It is very easy to implement. We can easily encode and decode.

2) It is the lowest number system available and hence any number system can be easily encoded into it.

3) We can construct circuits consisting of higher level variables with simple and or and not gates.

4) It is robust since we have only two values. so adding another value becomes difficult like noise.

5) It can be used as Universal Representation of data.
