COMPRESSION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
____ is a data compression algorithm that allows the original data to be perfectly reconstructed from the compressed data.
A
lossy compression
B
lossless compression
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Lossless compression is a class of data compression algorithms that allows the original data to be perfectly reconstructed from the compressed data. Lossless compression methods are reversible.

Detailed explanation-2: -The algorithms used in lossless compression are: Run Length Encoding. Lempel-Ziv-Welch (LZW) Huffman Coding.

Detailed explanation-3: -The Lempel-Ziv-Welch (LZW) algorithm is a data compression algorithm that is used to reduce the size of data files. It works by replacing repeated patterns of data with a single code. This reduces the amount of data that needs to be stored and transferred, making it more efficient and cost-effective.

Detailed explanation-4: -Lossless compression is a data compression algorithm that allows the original data to be perfectly reconstructed from the compressed data.
