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.
Swap file
A space on a hard disk 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 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.
Virtual host
See Virtual site
Virtual memory

system, allows programmers to use a very large range of memory or
storage addresses for stored data.
