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 techniques are used to reduce the size of files and data for efficient storage and transmission. Common methods include lossless compression, which preserves all data accurately, and lossy compression, which sacrifices some data to achieve higher compression rates. Examples of compression algorithms include ZIP for general purpose compression, JPEG for image compression, and MP3 for audio compression.
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.
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.
It shouldn't. DATA Compression just mininalizes the space it's taking up
Data compression allows for encoding information by using fewer bits.
Compression in data transfer refers to the process of reducing the file size of data being transmitted, allowing for faster transfer speeds and reduced data usage. This is achieved by encoding the data in a more efficient way before sending it, and then decoding it at the receiving end.
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.
Limiting factors in data compression include the type of data being compressed (e.g., text, images, video), the compression algorithm used, and the desired level of compression (lossless or lossy). Additionally, the processing power and memory available can also impact the compression effectiveness.
The areas of compression are lossless compression and lossy compression. Lossless compression reduces the file size without sacrificing any data quality, while lossy compression reduces the file size by discarding some data, which may lead to a decrease in quality.
