Remote Wake Up

A standard of WfM that provides the ability either to remotely wake a computer from a low-power sleep state or to remotely start a computer that is turned off but connected to a power source. Remote Wake Up, typically used to conserve power in large network organizations and to remotely perform maintenance/configuration operations, must be supported by an ACPI-compatible computer. Additionally, to start by a network connection, the network adapter must support WOL. To start by a telephone connection, the modem must support WOR.

RIMM

Rambus in-line memory module. A slim circuit board containing RDRAM chips. RIMMs are plugged into sockets on the computer's system board to add memory to the computer. They typically must be installed in matched pairs, meaning two sockets forming a pair must contain RIMMs of identical capacity, number of RDRAM chips, and speed. See also SIMM and DIMM.

RJ45

A form of connector resembling a standard telephone jack that is typically used to connect Ethernet and Token Ring network adapters and cables. Unlike a telephone jack, an RJ45 connector has eight wires instead of two, four, or six.

ROM

Read-only memory. Memory that stores data and programs that cannot be deleted or written to by the computer. ROM, unlike RAM, retains its contents even after you turn off your computer. Some programs essential to the operation of your computer reside in ROM.

RS-232

A long-established standard describing the interface for serial data communication between computers and related devices. See also DCE and DTE.

RTC

Real-time clock. Battery-powered clock circuitry on the system board that keeps the date and time after you turn off the computer.

RTCRST

Real-time clock reset. A jumper on the system board that can often be used for troubleshooting problems.
