When compressed data that is subsequently decompressed does not exactly match the original, yet it is considered close enough to the original to be usable, that algorithm is called a lossy compression. Contrast that with lossless compression, where the decompressed version exactly matches the original. Lossy compression is useful in audio and video, where exactness is not critical, while lossless compression is useful in data streams that must be preserved exactly. The lossy compression algorithm often results in more compact compressed results.
Yes, there are several algorithms for data compression, that is, store data in less space than it usually needs. However, not all data can be encrypted. Encryption basically takes advantage of some sort of repetition in data; once all repetition has been eliminated, data can be encrypted no more.Yes, there are several algorithms for data compression, that is, store data in less space than it usually needs.

mean does not mean the center of the data
what do you mean by data assembly?
The mean of a set of data is the sum of that data divided by the number of items of data.
Data Compression is a technique to minimize the space used by data in storing. So when we do compression of data, no data is loss.

There are some basic principles of data compression. They include advantages, disadvantages, and the history of compression. Types of compression include BZip2 and LZMA.
It shouldn't. DATA Compression just mininalizes the space it's taking up
Data de duplication is a process that eliminates duplicate copies of repeating data. The compression technique that it uses to function is called intelligent data compression.
Data compression allows for encoding information by using fewer bits.
Lossy= Is generally more effective but when opening file it loses some data. This is most noticeable in compressed pictures Lossless= Is the most common method of compression and loses none of the data
Data compression is basically used for communications as it enables devices to transmit or store the same amount of data in fewer bits. CCITT standard data compression technique for transmitting faxes, ARC and ZIP are the file compression formats and there is also data communication through modem.
Bandwidth compression is a term used in telecommunication, and it has two meanings. The first meaning of the term states that bandwidth compression is the reduction of bandwidth needed to forward a specific amount of data in a specific amount of time. The second meaning states that bandwidth compression is the reduction of time needed to forward a specific amount of data in a given bandwidth.

There is no straightforward conversion. An image that has (for example) 800 x 600 pixels needs to represent that many picture points. Without data compression, each picture element needs about three bytes (depending on the color depth); however, formats such as JPEG do use data compression, more precisely, lossy data compression - and the factor by which data is reduced with data compressed varies, depending on the image quality. That is, in lossy data compression, more compression means less quality.
