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 […]
- RAMbo drive
A DVD-RAM drive that can read and write CD-R and CD-RW media.
- RARP
Short for Reverse Address Resolution Protocol, a TCP/IP protocol that permits a physical address, such as an Ethernet address, to be translated into an IP address. Hosts such as diskless workstations often only know their hardware interface addresses, or MAC address, when booted but not their IP addresses. They must discover their IP addresses from […]
