Cavity wall insulation. Cavity wall insulation is used to reduce heat loss through a cavity wall by filling the air space with material that inhibits heat transfer. This immobilises the air within the cavity (air is still the actual insulator), preventing convection, and can substantially reduce space heating costs.
âStandardâ wiring puts both grounds at one end of the socket. âCKâ wiring puts grounds on one side of the socket. This makes no difference to an incandescent bulb, because the filament is not sensitive to polarity. However, installing âStandardâ wired LEDs in âCKâ sockets may cause them to catch fire or blow fuses.
A network socket is one endpoint in a communication flow between two programs running over a network. Sockets are created and used with a set of programming requests or function calls sometimes called the sockets application programming interface (API). The most common sockets API is the Berkeley UNIX C interface for sockets. Sockets can also be used for communication between processes within the same computer. This is the typical sequence of sockets requests from a server application in the connectionless context of the Internet in which a server handles many client requests and does not maintain a connection longer than the serving of the immediate request:
