Multimedia files are usually very large in size. Therefore for the purpose of the storage and transfer of large-sized multimedia files, the file sizes need to be reduced. Files which contain text and other files may also sometimes need to be encoded or compressed for the purpose of sending e-mail and also for other multimedia applications.
In the field of computer science, the term data compression is also known as source coding. The term data compression or source coding is defined as the process by which information is encoded using fewer bits (or other units which bear information) that a more obvious representation would use. This is due to the fact that the process of compression of data uses specific schemes for the encoding of the information.
The phrase data compression is also defined as the process by which data is converted from one format to another format which is physically smaller in size. The same logical information is stored using less physical information.
