cache (cache memory)
support. The cable support also contains the group and module ID labels and the rear
group service light-emitting diode (LED).
cache (cache memory). A small, fast memory holding recently accessed data designed to
speed up subsequent access to the same data. Cache memory is built from faster
memory chips than main memory, and it is most often used with process or main
memory but also used in network data transfer to maintain a local copy of data.
cached bindings. A copy in virtual memory of the data pages containing symbolic
references that were rebound when a loadfile was loaded. The cached bindings are
associated with a library import characterization that characterizes the set of loadfiles
to which the symbols were bound. If the same file is subsequently loaded in an
equivalent environment in the same processor, the cached bindings can be reused.

CAE. See common applications environment (CAE).
canonical input mode. For an Open System Services (OSS) process, a terminal input
mode in which data is not made available to the process until an entire logical line
(delimited by a newline, EOF, or EOL character) is entered. This mode is sometimes
called line mode or nontransparent mode. Contrast with noncanonical input mode
.
CAP. See cartridge access port (CAP).
Carbon Copy. A remote operations software application that enables a workstation in one
location to access, through a modem, a workstation in another location. Carbon Copy
is included with all system consoles, and service providers use it to dial in to system
consoles at customer sites. See also remote access
.
card cage. A structure made up of slots that hold components such as customer-
replaceable units (CRUs) and ServerNet adapters.
carrier. (1) A sheet-metal structure that allows a single-high ServerNet adapter to be
installed in a ServerNet adapter slot designed for a double-high ServerNet adapter.
(2) An electrical signal that carries data.
cartridge access port (CAP). The component on the tape libraries supported on HP
NonStop™ S-series systems where you insert cartridges into and remove cartridges
from the library.
caught signal. A programmatic signal that is delivered to a process that has a signal-
handling function for it. When the signal is caught, the process is interrupted, and the
signal-handling function executes.
CBB. See common base board (CBB).
CCITT. International Telegraph and Telephone Consultative Committee.
CCSA. See Common Communication ServerNet adapter (CCSA).
