operating system

The software that controls the allocation
and usage of hardware resources such as memory, central
processing unit (CPU) time, disk space, and peripheral

operational
range (for a product)
The date handling methods
within a software product are tailored to the needed
functionality. Various methods (algorithms) can be used
depending on the functions required, so each method may extend
normal functionality to a different date limit. Examples of
various date functionality include valid data ranges the
product will accept, valid dates for the file itself, and the
date ranges within which the product will initialize.
The operational range of a product indicates the
limits within which the product behaves as functionally
intended. Outside these limits the product may or may not
continue to function normally, depending of the specific
functions being used.
operational data
range
This term refers to the range of date
data that a software program will accept from the user. It
does not refer to data accuracy or the accuracy of
interpretations based on two-digit year shortcuts. (The latter
is handled by the "date window.")
Original
Equipment Manufacturer (OEM)
An OEM typically
purchases components from other manufacturers, integrates
these into its own product, and then sells that product to the
public.
OS/2
A protected mode,
virtual memory, multitasking operating system for personal
computers based on the Intel 80286, 80386, i486 and Pentium
processors. Important OS/2 subsystems include Presentation
