In instant messaging, federated IM networks are those that allow communications across different IM clients and platforms, similar to the way e-mail allows people to communicate regardless of which e-mail client they choose to use. Federated IM networks are those which maintain an open directory that allows other IM networks to message their users.
Many federated IM networks communicate using an open standard, such as Jabber/XMPP. IM Networks using XMPP provide open communications with other XMPP-based networks. Some federated networks work on the basis of interoperability where the software from two or more vendors share data between the different proprietary platforms.

In telecommunications, a femtocell is a small cellular base station — or a wireless access point — that is typically used to improve indoor cellular reception inside a home or small business. A femtocell connects to the carrier’s network via broadband and can support up to five mobile phones. The main benefits to using femtocell […]
- ferrite core
A form of core memory for data storage. The core is made of tiny ferrite rings threaded with wires that are magnetized by electrical current. The two possible polarities of magnetization were used to represent the binary values zero and one. Data are stored by magnetizing an array of cores in a particular combination of […]
(n.) A fluid in which fine particles of iron, magnetite or cobalt are suspended, typically in an oil. A 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 […]
