Glossary
Random Access Memory
The temporary storage device for programs and data for a computer’s central processing unit.
CFN System devices use battery-backed-up RAM, so the contents of the memory are
preserved even during a power failure.
Read Only Memory
Computer memory that stores information permanently and that cannot be altered by normal
operation of the computer.
Record
A collection of related information treated as a unit. For example, all the information about a
completed transaction makes one transaction record.
Remote
A remote command means the Site Controller is accessed through its remote port by a remote
host. Remote verification means transactions are authorized by a host system.
Return Key
The key that on a typewriter would actually return the carriage. On the Site Controller data
terminal it signals the end of a line or the entry of a command. Also known on some terminals
as the Enter key.
ROM
Refer to “Read Only Memory” .
RS-232
An industry-standard serial interface used to attach devices such as modems, printers, to your
Site Controller. A type of cable.
RS-422/485
An industry-standard serial interface used to attach reader terminals, pump control units, and
other CFN System devices to the Site Controller. A type of cable. The 422 is a single device,
the 485 a multiple device.
Run
When the Site Controller is running, it is allowing transactions. You can also run—that is,
execute—a program or command file.
SCSI
Abbreviation of small computer system interface. Pronounced scuzzy, SCSI is a parallel
interface standard used by Macintosh
® computers, some PCs, and many UNIX ® systems for
attaching peripheral devices to computers. SCSI interfaces provide for faster data
transmission rates (up to 40 megabytes per second) than standard serial and parallel ports. In
addition, you can attach many devices to a single SCSI port, so that SCSI is really an I/O bus
rather than simply an interface.
