IOG is an acronym for Input Output Group and it is using these drives that we would perform such tasks as loading the exchange data from OD (a.k.a MO) into the CPUs memory banks or transferring a backup of the exchange data out to portable media.
In recent years these drives have become further redundant as backup files and correction packages are increasingly transferred using the File Transfer Protocol (FTP).
