Acronym for random-access memory. The computer's primary temporary storage area for program instructions and data. Each location in RAM is identified by a number called a memory address. Any information stored in RAM is lost when you turn off your computer. The higher the refresh rate, the less video flicker can be seen by the human eye. The higher refresh rates are also noninterlaced. Abbreviation for radio frequency interference. Acronym for random-access memory digital-to-analog converter. Abbreviation for red/green/blue. A read-only file is one that you are prohibited from editing or deleting. A file can have read-only status if: Its read-only attribute is enabled. It resides on a physically writeprotected diskette or on a diskette in a write-protected drive. It is located on a network in a directory to which the system administrator has assigned readonly rights to you. A text file included with a software package or hardware product that contains information supplementing or updating the documentation for the software or hardware. Typically, readme files provide installation information, describe new product enhancements or corrections that have not yet been documented, and list known problems or other things you need to be aware of as you use the software or hardware. An operating mode supported by 80286 or higher processors, real mode imitates the architecture of an 8086 processor. The rate at which the monitor redraws the video image on the monitor screen. More precisely, the refresh rate is the frequency, measured in Hz, at which the screen's horizontal lines are recharged (sometimes also referred to as its vertical frequency). Acronym for read-only memory. Your computer contains some programs essential to its operation in ROM code. Unlike RAM, a ROM chip retains its contents even after you turn off your computer. Examples of code in ROM include the program that initiates your computer's boot routine and the POST. Abbreviation for revolutions per minute. Abbreviation for real-time clock. Batterypowered clock circuitry inside the computer that keeps the date and time after you turn off the computer. Acronym for small computer system interface. An I/O bus interface with faster data transmission rates than standard ports. You can connect up to seven devices (15 for some newer SCSI types) to one SCSI interface. Abbreviation for SCSI device management system. Abbreviation for synchronous dynamic random-access memory. SDRAM is a memory technology that improves the performance of your system's memory subsystem by reducing the need for wait states. SDRAM devices have a synchronous interface to the devices to which they are connected and are governed by the system clock. These features reduce the need for wait states often required for 12 Dell Precision 610 Mini Tower Systems User's Guide
