ISO/IEC 27041:
ühtainsat ülesannet täitev:
- meetod kõigi kustutamata failide taasteks seadmelt saab olla atomaarne ainult siis, kui ta toetub ainult failisüsteemi metaandmete kasutamisele
- kõigi kustutatud failide taaste meetod ei ole tõenäoliselt atomaarne, sest nõuab alammeetodeid failistruktuuride tuvastuseks ja ekstraktimiseks andmete hulgast faili sisu (.jpg, .png, .odt, XML vm) teadmise põhjal
= performing a single function only
Note. A method for recovery of all live files from a device can be atomic if it relies solely on the use of filesystem meta-data. A method for recovery of all deleted files is unlikely to be atomic as it will require sub-methods which identify and extract particular file structures from the data on the storage device based on knowledge of file contents (e.g. .jpg, .png, .odt, XML, etc.).

atomic resource -- atomaarne ressurss
atomic type -- atomaartüüp
