hello
i need some help answering an IT related seen question for my exams relating to the OS and database's
- field validation check appropriate for Item Number, Customer Number and Item Quantity?
two distince types of resource managed by the OS on a stand alone pc, - i think memory and cpu but i could be wrong?
plus one other role - i say file management but again i could be wrong.
one task a network os will have as opposed to a stand alone, - i was gonna say managing application resources or user access but don't know if this is enough or too obvious
any help greatly appreciated
Kaz
