What is Decoder ? | Decoder with Example?

A decoder is like a special kind of puzzle solver that turns secrets into meanings, just like how you turn a jumbled up message back into something you can read.

Imagine you have a box full of different colored blocks, and each color stands for a letter. If someone gives you a coded message made from those colors, the decoder is what helps you figure out which letters go with which colors, turning the secret code into real words.

Think of it like this: You have a friend who sends you notes using only shapes. A triangle means “cat,” a circle means “dog,” and a square means “tree.” The decoder is like your brain when you see those shapes and know what they mean, it helps you turn the shapes back into words.

Without a decoder, you’d just have a bunch of strange symbols, like trying to read a book written in a language you don’t understand. But with it, everything clicks together, and you can read the message clearly!
