Appendix F: Glossary
Small Computer System Interface (SCSI)
A parallel interface standard used by PCs, some Apple Macintosh computers
and many Unix systems for attaching peripheral devices to computers. SCSI
interfaces provide for faster data transmission rates (up to 160 Mb/s) than
standard serial and parallel ports. In addition, you can attach many devices to
a single SCSI port, so that SCSI is really an input/output bus rather than
simply an interface.
SMB
See Server Message Block (SMB).
SMTP
See Simple Mail Transfer Protocol (SMTP).
SNMP
See Simple Network Management Protocol (SNMP).
SSL
See Secure Sockets Layer (SSL).
Subnet mask
A number that, in conjunction with an IP address, defines the set of
IP addresses that are considered "local." For example, if your IP address is
192.168.25.77 and your subnet mask is 255.255.255.0, then addresses
between 192.168.25.1 and 192.168.25.255 are considered local. Also known
as netmask.
Swap file
A space on a hard disk drive used as the virtual memory extension of a
computer's random access memory (RAM). Having a swap file allows the
computer's operating system to pretend that it has more RAM than it
actually does. The least-recently-used files in RAM are "swapped out" to
your hard disk drive until they are needed later; in their place, new program
segments or data can be "swapped in" to RAM.
Transmission Control Protocol (TCP)
A connection-oriented transport-layer protocol that provides reliable
full-duplex data transmission. TCP is part of the TCP/IP protocol stack.
Transmission Control Protocol/Internet Protocol (TCP/IP)
A common name for the suite of protocols developed in the 1970s to support
the construction of worldwide internetworks. TCP and IP are the two
best-known protocols in the suite. The TCP/IP protocols enable computers
and networks to connect to an intranet or Internet.
