Data compression is needed because it allows the data to be stored in an area without taking up an unnecessary amount of space. Data compression uses a series of algorithms to reduce the amount of real space that the data would normally take up.

Data compression: Data compression, the process of reducing the amount of data needed for the storage or transmission of a given piece of information, typically by the use of encoding techniques. Compression predates digital technology, having been used in Morse Code, which assigned the shortest codes to the most

en.wikipedia.org/wiki/Data_compression

Thus, one can consider data compression as data differencing with empty source data, the compressed file corresponding to a "difference from nothing." This is the same as considering absolute entropy (corresponding to data compression) as a special case of relative entropy (corresponding to data differencing) with no initial data.

File compression includes methods of reducing the space necessary to store a file on a computer system. Compressed files require significantly less storage space than uncompressed files, although compression may lead to the loss of some data. File compression is intended to reduce the storage requirements of data that ...

Data compression is an approach (there are several strategies) by which the physical storage actually required is able to be less than the designed size, when the data actually stored does not require all of the space. Typically, the DBMS handles this compression during writes to the table.

Why do we need compression? ... would have to be very low before it would be feasible to use it for the staggering amounts of data required by HDTV. Finally, even if the storage and transportation problems of digital video were overcome, the processing power needed to manage such volumes of data would make the receiver hardware very expensive. ...

Data compression is a process by which the file size is reduced by re-encoding the file data to use fewer bits of storage than the original file. The original file can then be recreated from the compressed representation using a reverse process called decompression. There are several different algorithms and implementations that allow you to compress your files, some of which perform better ...

You’d need several of them together before you could even hope to store a single movie. What’s more is that things like networks cannot send that amount of data through fast ...

With lossy compression we get rid of data, which is why we need to distinguish data from information. Lossless compression allows the reinstatement of a file to its original state, without the loss of a single bit of data, when the file is uncompressed. Lossless compression is the usual approach with executables, as well as text and spreadsheet ...

Data Compression; Out of these, when we think of video compression we always tend to think of data compression, and forget every other type. Data compression is the power of algorithms to find ‘patterns’ in the video to ‘reduce’ duplicates. To know more about data compression, check out Lossy vs Lossless compression.
