If you're talking about "document retention", it depends on the type of information contained in the data. As a general rule, however, you should only keep business information for as long as it is required by law, or for some specific business reason.
It depends on how you define "company" and what type of "data". A prior employer can keep information for as long as they choose to. However most "companies" purge their files after seven years.
A data entry clerk is primarily responsible for 'computerising' written data. One example would be... Membership forms at a large gym - the clerk would take the written membership for, and enter the details into the database, so the company can keep in touch with its membership.
There are several types of storage depending on how long you want to keep data. 1 Hard disk, internal within the computer normally, you can get external drives as well, which is flexible storage but does not lose anything when the power is switched off. Hard disks can fail when old. 2 USB flash drives and memory cards, not disk but fixed memory, should never lose data, can be rewritten to any number of times. 3 CD / DVD Data can be backed up or written to Cd's and DVDs for long term storage. RW (rewritable) disks can be changed after first writing, normal disks are written once and keep the data as long as they are stored correctly.

CDs, DVDs, and hard drives are storage devices that can contain permanently written data. Once data is written onto these devices, it remains until it is intentionally deleted or overwritten.
