Volume (compression)
Encyclopedia
A volume is a term in data compression
for a file that has been compressed and split into different parts.
There are many advantages in having a compression utility with the ability for compression into volumes. First, it allows an individual to download the file in segments at his or her own pace. As well if there is a corruption only one volume is affected instead of the whole—which can be corrected using parity file
s. Second, it allows compression to a volume size compatible with removable media. For example, compressing a backup into 700MB chunks for easy storage on CDs.

Parity file
Parity files are files that are created to accompany data files, and are used to preserve data integrity and assist in data recovery. They are useful when data files are transmitted or stored on less-than-perfect media such as newsgroup messages, satellite transmission, or optical disk...
