Network interface Card (NIC)
A NIC is a device that handles
communication between a device and other devices on a network.
NVRAM
Non-Volatile Random Access Memory is a type of
memory that retains its contents when power is turned off. One
type of NVRAM is SRAM that is made non-volatile by connecting
it to a constant power source such as a battery. Another type of
NVRAM uses EEPROM chips to save its contents when power is
turned off. In this case, NVRAM is composed of a combination of
SRAM and EEPROM chips.
P PCI
The PCI bus typically runs at speeds of 33 MHZ or 66 MHZ
and is usually 32 bits wide. This means that it passes 32 bits of data
simultaneously as if down 32 separate wires. Some of the most
recent computers include "wider" 64-bit PCI buses, and already
certain very high end video capture cards offer improved
performance if connected to a 64-bit PCI bus.
Prism Storage Architecture
TM
Accommodates a wide range of
needs from large data centers to work groups to remote sites and is
based on the PCI bus. Scalable Prism options provide "plug and
play" serviceability, eliminating expensive upgrades and library
obsolescence. It improves manageability with library partitioning,
SNMP integration, e-mail notification, and Web-based
management features.
R RAID
Redundant Array of Independent Disks is a technology
through which several physical storage disks are grouped into an
array that appears to an operating system as one or more physical
devices.
Reports
Refers to the report options on the touch screen GUI’s
Service screen.
Robotics
As used in the context of ATL automated tape libraries;
the X-axis, Y-axis, and Z-axis mechanical assemblies inside the
library used to move tape cartridges.
RS-232C
Short for Recommended Standard-232C, a standard
interface approved by the Electronic Industries Association (EIA)
for connecting serial devices. This standard is for ASYNCHRO-
NOUS TRANSFER between computer equipment and accessories.
