Structured Cabling
With structured cabling, maximum permissible cable lengths are defined
(EIA/TIA 568, IS 11801) for site, building and floor cabling, with recom-
mendations for topologies also indicated.
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
Subnet masks can be used to manipulate the address ranges in the IP address
area in reference to the number of subnets and hosts. A standard subnet
mask, for example, is 255.255.255.0.
S-UTP (Screened Unshielded Twisted-Pair)
Screened twisted pair cable, which only has one external shield. However,
the twisted pair cables are not shielded from each other.
Switch
Switches are comparable to bridges, but with several outputs. Each output
uses the full ETHERNET bandwidth. Each output uses the full ETHERNET
bandwidth. Switches learn which nodes are connected and filter the informa-
tion transmitted over the network accordingly. Switches learn which nodes
are connected and filter the information transmitted over the network ac-
cordingly.
Switched ETHERNET
ETHERNET network set up using switches. There are a multitude of appli-
cations for switching technologies. ETHERNET switching is becoming in-
creasingly popular in local networks as it allows deterministic ETHERNET.
