S
server | In a client/server architecture, a dedicated computer that supplies files or services such as file transfer, |
| remote login, or printing to clients. |
scope | The set of IP addresses that a DHCP server can lease to clients. |
service provider | A company providing cable data services to subscribers. |
SID | A service ID is a unique |
| identifies the traffic type it carries (for example, data or voice). The SID provides the basis for the |
| CMTS to allocate bandwidth to the cable modem and implement CoS. |
SDU | service data unit |
SME | small and medium enterprise |
SMTP | Simple Mail Transfer Protocol is a standard Internet protocol for transferring |
SNMP | Simple Network Management Protocol is a standard to monitor and manage networks and network |
| devices. Data is exchanged using PDU messages. |
SOHO | small office home office |
spectrum | A specified range of frequencies used for transmission of electromagnetic signals. |
spectrum | An allocation of portions of the available electromagnetic spectrum for specific services, such as AM, |
allocation | FM, or personal communications. |
splitter | A device that divides the signal from an input cable between two or more cables. |
stateful | A type of firewall that tracks each connection traversing all firewall interfaces to ensure validity. In |
inspection | addition to examining the source and destination in the packet header based on static rules, a stateful |
| inspection firewall: |
| • Examines packet headers on context established by previous packets that traversed the firewall |
| • Monitors the connection state and saves it in a table |
| • Closes ports until a connection to a specific port is requested |
| • May examine the packet contents up through the application layer to determine more than just the |
| source and destination |
| A |
static filter | A type of firewall that examines the source and destination in the packet header based on |
| |
static IP | An IP address that is permanently assigned to a host. Normally, a static IP address must be assigned |
address | manually. The opposite of dynamic IP address. |
static route | A |
station | IEEE 802.11b term for wireless client. |
subscriber | A home or office user who accesses television, data, or other services from a cable provider. |
subnet mask | A bit mask that is logically ANDed with the destination IP address of a packet to determine the network |
| address. A router routes packets using the network address. |
subnetwork | A part of a network; commonly abbreviated “subnet.” When subnetting is used, the host portion of the |
| IP address is divided into a subnet and host number. Hosts and routers use the subnet mask to |
| identify the bits used for the network and subnet number. |
