Data compression - Data compression

Japanese: データ圧縮 - データあっしゅく(英語表記)data compression
Data compression - Data compression
A process of reducing the length of data so that it can be reproduced. Data compression can reduce transmission time and the amount of storage media used. Data compression is a type of encoding, and is also called source encoding or high-efficiency encoding. Data compression is broadly classified into two types: lossless compression, which compresses data so that the original data (bit string) can be reproduced perfectly when restored, and lossy compression, which compresses data so that only the necessary information can be restored.

Japanese:
再現できる形でデータ長を小さくする処理。データ圧縮を行うことで伝送時間や記憶媒体の使用量を削減することができる。データ圧縮は符号化の一種であり,情報源符号化や高能率符号化と呼ばれることもある。 データ圧縮は復元したときに元のデータ(ビット列)を完全に再現できるように圧縮する無歪み圧縮(可逆符号化,lossless compression)と必要な情報だけを復元できるように圧縮する歪みありの圧縮(非可逆符号化,lossy compression)の二つに大きく分類される。
