SOAP
Short form for "Simple Object Access Protocol". XML is a standard for
Meta data, the access on the XML objects takes place via SOAP.The
standard defines, how transactions via internet and XML can be done and
how dynamic Web services over distributed networks can be used.
Socket
Is a software interface introduced with BSD-UNIX for inter-process
communication. Sockets are also possible in the network via TCP/IP. As
from Windows 3.11, they are also available in Microsoft operating systems.
STP
With the STP cable (Shielded twisted pair) it acts around a symmetrical
cable with in pairs stranded and protected veins. The classical STP cable is a
multi-core cable, whose stranded conductors are isolated. The conductors of
the STP cable are individually protected. It has no total screen.
S-STP
Beside the STP cables there is cable, which has total shielding from foil or
network shielding additionally to the single shielding of the conductors still
another. These cables are called S/STP cables: Screened/Shielded twisted
pair.
Structured cabling
This specifies the maximum permissible cable lengths (EIA/TIA 568, IS
11801) and gives recommendations for the different types topology for
ground area, building and floor cabling.
Subnet
A portion of a network that shares the same network address as the other
portions. These subnets are distinguished through the subnet mask.
Subnet mask
The subnet mask can be used to manipulate the address areas in the IP
address room with reference to the number of subnets and subscribers. A
standard subnet mask is, for example, 255.255.255.0.
S-UTP
Screened unshielded twisted pair cable which only has one external shield.
However, the twisted pair cables are not shielded from each other.
