Nagware: Software or programming that routinely issues a pop-up window or other form of visual interface asking the user to register a product, purchase an application or take another form of action. Nagware is typically used in reference to shareware, which typically offers a free-trial period of use for the application and then requests that the user purchase the rights to use the software indefinitely. The term gets its name from the idea that the reminders "nag" the user into taking some particular action, as they will keep appearing until the desired action has been performed. DID: Short for direct inward dialing (also known as direct dialing inward), a service of an LEC or local phone company that allows an organisation to have numerous individual phone numbers for each person or workstation in its PBX system that run off of a small block of dedicated telephone numbers. DID allows the multiple lines to be connected to the PBX all at once without requiring each to have a physical line connecting to the PBX. Ferrofluid: A fluid in which fine particles of iron, magnetite or cobalt are suspended, typically in oil. Ferrofluid is superparamagnetic and can create liquid seals held in position by magnetic fields. One application of ferrofluids is to keep dust off of the drive shafts of magnetic disk drives. Ferrofluids were invented by NASA as a way to control the flow of liquid fuels in space. A+:
