Decode, Encode, Decompress, Compress?


The Decode and Encode, or encoding and decoding or known as Compress Unzip (decompress)!



Encode = Compress = Code:



Also called: to code, to encode, to cipher

Data is merged (smaller)

Decode = decompress = deflate



also called: to decipher, to decode, to decrypt, to uncode

The data is read and reset to the original state!

A simple example of the number: 0000011112222222

Compressed (Encoded)
00000111112222222 = 5x0,4x1,7x2

Decompress
5x0 = 00000
4x1 = 1111
7x2 = 2222222
00000 & 1111 & 2222222 = 00000111112222222

PS: Even if you know it, you always will have a thought-turner at these words!

This is a good explanation of encoding and decoding, also known as compressing and unpacking.

Encoding or compression is the process of representing data in a specific form that requires less storage space than the original representation. The goal is to store or transmit the data more efficiently by removing redundant information or replacing it with more efficient representations. This can be done through various techniques, such as replacing frequently occurring patterns with shorter symbols or removing unnecessary information.

Decoding or unpacking is the process of returning the compressed data to its original form by using the encoding information to restore the original data. The goal is to return the data to a state identical to the original so that it can be read or used correctly.

Your example with the numbers illustrates this process very well. Compression reduced the repeated numbers and replaced them with a more compact representation. Decompression then returned the compressed data to its original form by using the compression information to restore the original data.

In computing, encoding and decoding are used in a variety of applications, including data compression, encrypting data for security, and converting data between different formats or protocols.
