RAIN
Short for Redundant Array of Independent Nodes, RAIN is a data storage and protection system architecture. It uses an open architecture that combines standard computing and networking hardware with management software to create a system that is more distributed and scalable. RAIN is based on the idea of linking RAID nodes together into a larger storage mechanism. In a RAIN set-up there are multiple servers, each with disk drive and RAID functionality, all working together as a RAIN, or a parity or mirrored implementation. RAIN may also be called storage grid.

- Random Access Memory (RAM)
RAM (pronounced ramm) is an acronym for random access memory, a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is the most common type of memory found in computers and other devices, such as printers. Main Types of RAM […]
- RAM cache
(1) Same as L2 cache. (2) On Apple Macintosh computers, the term RAM cache refers to a disk cache.
- RAMDAC
Short for Random Access Memory Digital-to-Analog Converter, a single chip on video adapter cards. The RAMDAC’s role is to convert digitally encoded images into analog signals that can be displayed by a monitor. A RAMDAC actually consists of four different components – SRAM to store the color map and three digital-to-analog converters (DACs), one for […]
- RAM disk
Refers to RAM that has been configured to simulate a disk drive. You can access files on a RAM disk as you would access files on a real disk. RAM disks, however, are approximately a thousand times faster than hard disk drives. They are particularly useful, therefore, for applications that require frequent disk accesses. Because […]
- RAM latency
A delay in transmitting data between a computer’s RAM and its processor. Since RAM is not necessarily fast compared to the computer’s processor, RAM latency can occur, causing a delay between the time a computer’s hardware recognizes the need for a RAM access (initiates a request for data) and the time the data or instruction […]
