Glossary
SLA Service Level Agreement. A contract between a service provider and the end
user, which stipulates and commits the service provider to a required level
of service. An SLA relates to issues such as specified level of service,
support options, enforcement or penalty provisions for services not
provided, a guaranteed level of system performance as relates to downtime
or uptime, a specified level of customer support and what software or
hardware will be provided and for what fee.
SME Small and Medium-sized Enterprises. SMEs are small-scale entrepreneurial
private enterprises: they are usually defined as having less than 250
employees, but most have far fewer.
SNAP Sub Network Access Protocol
SNMP Simple Network Management Protocol. A network management protocol
that provides a means to monitor and control network devices, and to
manage configurations, statistics collection, performance, and security.
SNMP works by sending messages, called protocol data units (PDUs), to
different parts of a network. SNMP-compliant devices, called agents, store
data about themselves in Management Information Bases (MIBs) and return
this data to the SNMP requesters.
SNR Signal to Noise Ratio. The ratio of the amplitude of a desired analog or
digital data signal to the amplitude of noise in a transmission channel at a
specific point in time. SNR is typically expressed logarithmically in decibels
(dB). SNR measures the quality of a transmission channel or a signal over a
network channel. The greater the ratio, the easier it is to identify and
subsequently isolate and eliminate the effects of noise. SNR also is
abbreviated as S/N.
SOHO Small Office Home Office. A term that refers to the small or home office
environment and the business culture that surrounds it. Typically it refers
to an office or business with ten or fewer computers and/or employees.
SRC Source
SU Subscriber Unit
TCP Transmission Control Protocol. Connection-oriented transport layer protocol
that provides reliable full-duplex data transmission. TCP is the part of the
TCP/IP suite of protocols that is responsible for forming data connections
between nodes that are reliable, as opposed to IP, which is connectionless
and unreliable.
