(1) Acronym for Standard Performance Evaluation Corporation, a nonprofit corporation set up by many computer and microprocessor vendors to create a standard set of benchmark tests. The most widely used set of tests, known as SPEC CPU2000 contains two benchmark suites: CINT2000 for measuring and comparing compute-intensive integer performance, and CFP2000 for measuring and comparing compute-intensive floating point performance. The SPEC CPU2000 benchmark tests are also called CPU2000 tests.
SPEC CPU95 preceded SPEC CPU2000 which will be followed by CPU2006.
(2) Short for specification, as in a functional specification.
Short for Sender Policy Framework, an extension of SMTP that stops e-mail spammers from forging the “From” fields in an e-mail. As SMTP itself does not carry an authenticating mechanism, the SPF extension provides the authentication scheme by specifying which computers are authorized to send email from a specific domain. In order to use SPF, […]
Acronym for Service Profile Identifier, a number that identifies a specific ISDN line. When you obtain ISDN service, your telephone company assigns a SPID to your line. Part of the initialization procedure is to configure your ISDN terminal adapter to use this SPID. Most telephone companies in the U.S. use the Generic SPID Format, which […]
Short for single point of failure, a generic phrase for any component of a system that upon failure will cause a malfunction in the entire system. A SPOF can be a hardware or electrical component or a software component. Each time a system expands (e.g., adding a workstation to a network or adding a new […]
SPN, short for service principal name, is the name by which a client uniquely identifies an instance of a service. If you install multiple instances of a service on computers throughout a forest, each instance must have its own SPN. A given service instance can have multiple SPNs if there are multiple names that clients […]
Short for Sequenced Packet Exchange, a transport layer protocol (layer 4 of the OSI Model) used in Novell Netware networks. The SPX layer sits on top of the IPX layer (layer 3) and provides connection-oriented services between two nodes on the network. SPX is used primarily by client/server applications. Whereas the IPX protocol is similar […]
