What are Encoders and Decoders?

- Encoders are logic circuits which change a set of signals into a code using a certain logic. It has a set of input signals of which only one line is active at a certain instant of time.

- Decoders are logic circuits which accept a set of inputs that represent a binary number and activate only the output that corresponds to the input number. It produces only one output as high for an input set.

- Encoding and Decoding is done for the safe transmission of data.
Now a days, data is encrypted using 128-bit encryption. It may have 2 to the power of 128 possible combinations. This is widely regarded as immune to brutal force attacks from hackers simply because it would take too long to crack.
