Hidden nodes in a wireless network are nodes that are out of range of other nodes or a collection of nodes. Consider a physical star topology with an access point with many nodes surrounding it in a circular fashion: each node is within communication range of the AP, but the nodes cannot communicate with each other.
Source: [1] Node D is unaware of the ongoing data transfer between node A and node B. Node D has data to send to node C, which is in the transmission range of node B. D initiates the process by sending an RTS frame to node C. Node C has already deferred its transmission until the completion of the current data transfer between node A and node B (to avoid co-channel interference at node B).
A swage terminal is a product used to terminate wire. A swaging machine is used to terminate the wire. The wire is passed into a deep hole in the swage terminal which is then pressed onto the terminal by applying force. This type of product is used in the architectural and marine industries.
The yellow P+N+E, 4h (120°) plug is a single phase connector that is in widespread use on the British Isles for 110 V building site and fairground applications. A popular model of this socket type is marketed under the brand name MK Commando [12] which leads some users to refer to all IEC 60309 sockets by the generic trademark Commando sockets.
A can wrench is a wrench made to open a telephone distribution terminal also called a telco can or demarcation point box. One end of the can wrench is a 7/16 inch hex socket used for recessed fasteners on closures, and the other end is a 3/8 inch hex socket for use on binding posts.
A Prontor-Compur connection (also known as a PC connector, PC terminal, or PC socket) is a standard 3.5 mm (1/8") electrical connector (as defined in ISO 519 [1]) used in photography to synchronize the shutter to the flash.
Terminal blocks (also called terminal boards or strips) provide a convenient means of connecting individual electrical wires without a splice or physically joining the ends. Since terminal blocks are readily available for a wide range of wire sizes and terminal quantity, they are one of the most flexible types of electrical connector available.
The most common form of HTTP tunneling is the standardized HTTP CONNECT method. [1] [2] In this mechanism, the client asks an HTTP proxy server to forward the TCP connection to the desired destination.
