| There are two versions of RIP: version and version II. |

routing | Forwarding data between your network and the Internet on the most |
| efficient route, based on the data’s destination IP address and current |
| network conditions. A device that performs routing is called a router. |
rule | See filtering rule, NAT rule. |
SDNS | Secondary Domain Name System (server) A DNS server that can be |
| used if the primary DSN server is not available. See DNS. |
SNMP | Simple Network Management Protocol The TCP/IP protocol used |
| for network management. |
Splitter | A device that splits off the voice component of the DSL signal to a |
| separate line, so that data and telephone service each have their own |
| wiring and jacks. The splitter is installed by your telephone company |
| where the DSL line enters your home. The CO also contains splitters |
| that separate the voice and data signals, sending voice to the PSTN |
| and data on |
| splitterless, microfilter. |
splitterless | A type of DSL installation where no splitter is installed, saving the |
| cost of a service call by the telephone company. Instead, each jack |
| in the home carries both voice and data, requiring a microfilter for |
| each telephone to prevent interference from the data signal. ADSL |
| is usually splitterless; if you are unsure if your installation has a |
| splitter, ask your DSL provider. See also splitter, microfilter. |
STUN | Simple Traversal of UDP (User Datagram Protocol) through NAT |
| (Network Address Translation) |
subnet | A subnet is a portion of a network. The subnet is distinguished |
| from the larger network by a subnet mask which selects some of |
| the computers of the network and excludes all others. The subnet’s |
| computers remain physically connected to the rest of the parent |
| network, but they are treated as though they were on a separate |
| network. See also network mask. |
Subnet mask | A mask that defines a subnet. See also network mask. |
TCP | See TCP/IP. |
TCP/IP | Transmission Control Protocol/Internet Protocol The basic protocols |
| used on the Internet. TCP is responsible for dividing data up into |
| packets for delivery and reassembling them at the destination, |
