OCS

(1) (Office Communications Server) Software from Microsoft that provides the infrastructure for instant messaging (IM), audio, video and Web conferencing and voice over IP (VoIP). Supporting the SIP and SIMPLE protocols, OCS evolved from the previous Live Communications Server 2006 and the instant messaging function in Exchange 2000. The client components for OCS 2007 are Microsoft Office Communicator 2007 and LiveMeeting. See SIP and SIMPLE.

(2) (Open Computer and Software Inventory) Software that automatically collects data about the hardware and software in the network for asset management and inventory purposes. OCS software agents gather the data by residing within the Windows, Linux, Mac, Solaris and AIX machines themselves. For more information, visit www.ocsinventory-ng.org.

(3) (Occupant Classification System) An automobile safety system that uses dual-stage airbags and pressure sensors to determine the size and weight of the person in the front passenger seat. If an accident occurs that sets off the airbags, they would deploy fully for an adult, but only partially or not at all for a child. Based on how a person sat in the seat, earlier systems were not always able to differentiate adults from children, but they have greatly improved.
