What is Huffman coding explain?

Huffman coding is a method of data compression that is independent of the data type, that is, the data could represent an image, audio or spreadsheet. This compression scheme is used in JPEG and MPEG-2. Huffman coding works by looking at the data stream that makes up the file to be compressed.

Where is Huffman coding used?

In computer science and information theory, a Huffman code is a particular type of optimal prefix code that is commonly used for lossless data compression.

How do you write Huffman code?

Huffman code is obtained from the Huffman tree. Huffman code is a = 000, b = 001, c = 010, d = 011, e = 1. This is the optimum (minimum-cost) prefix code for this distribution. Given an alphabet A with frequency distribution f(a) : a ∈ A.

Is Huffman coding lossy or lossless?

Huffman Coding is a method of lossless compression. Lossless compression is valuable because it can reduce the amount of information (or in your computer, memory) needed to communicate the exact same message. That means that the process is perfectly invertible. Lossy compression on the otherhand will lose information.
