The local network is a virtual domain, broadcast separate network switch.
every Switch by default, a domain is broadcast, but to prevent a storm of broadcast packets or reducing broadcast packets on Layer 2, you can create a local area network Virtual, a switch to two-or multi-domain plays a distinct breakdown.
the two computers to a switch are connected, if every A in a local area network virtual be different to be able to communicate at Layer 2 will not be....
Couples twisted (UTP), a form of wiring in which a wire conductor, two to two together have twisted up the electromagnetic disturbances resulting from external sources to neutralize the formation.
in the string, twisted rings, wire, causes the conversion tube, the magnetic signal can be.In stranded wire, balanced, etc., usually two-strand wire signals equal and opposite in a separate data transfer, and in the end combined together.It is these two strands of wire, the amount of electromagnetic disturbances (EMI) similar but with a phase difference of 180 degree are, it would reduce the power of the signal, disturbing the Pointer of the magnetic in this compound.
UTP cable is one of the most common cable used in telecommunication networks and computer. six types of UTP cable different there that can be used according to the type of network and desired goals of their use . CAT5 cable, etc. the most common type of UTP cable should be considered....
Di Slam (DSLAM), which is an acronym combining Digital Subscriber Line Access Multiplexer. from the series of network that the phone lines allow it to more quickly connect to the internet. Di Slam usually, in telecommunication centers installed and the signals from several subscriber lines, DSL, receive. Then the signals for the combination (re-multiplexing), and carried on a line of super-fast ATM that the backbone can be puts....
Interface, CNN type of common interface AR F, which is the head, cable can be closed. From the interface, CNN, for communications, signals, RSS, PDF, etc. signals,. MOV, amateur radio, systems, radio stations, airlines, etc. and a large variety of test machine, electronic used....
