compress, compactar:
Reduzir o tamanho de um conjunto de dados, como um arquivo ou mensagem de comunicação, de modo que seja possível armazená-lo com menos espaço ou transmiti-lo com uma largura de banda menor. Os dados podem ser compactados removendo-se sequências de bits repetidas e substituindo-as pela forma resumida que consome menos espaço; a restauração das sequências repetidas descompacta os dados. É necessário usar métodos de compactação sem perdas com arquivos de texto, códigos e dados numéricos; a compactação com perdas pode ser usada para arquivos de vídeo e de som. Pesquise também lossless compression (compactação sem perdas); lossy compression (compactação com perdas).
