EMCElectromagnetic CompatibilityEMIelectromagnetic interferenceEMMexpanded memory manager. A utility that uses extended memory to emulate expanded memory on computers with an Intel386™ or highermicroprocessor.EMSExpanded Memory SpecificationEPROMerasable programmable read-only memoryESDelectrostatic dischargeexpanded memoryA technique for accessing RAM above 1 MB. To enable expanded memory on your computer, you must use an EMM. You should configure yoursystem to support expanded memory only if you run application programs that can use (or require) expanded memory.expansion busYour computer contains an expansion bus that allows the microprocessor to communicate with controllers for peripheral devices, such as anetwork card or an internal modem.expansion-card connectorA connector on the computer's system board for plugging in an expansion card.extended memoryRAM above 1 MB. Most software that can use it, such as the Windows operating system, requires that extended memory be under the control of anXMM.external cache memoryA RAM cache using SRAM chips. Because SRAM chips operate at several times the speed of DRAM chips, the microprocessor can retrieve dataand instructions faster from external cache memory than from RAM.FFFahrenheitFATfile allocation table. The file system structure used by MS-DOS to organize and keep track of file storage. The Microsoft Windows NT® and IBM®OS/2® operating systems can optionally use a FAT file system structure.FCCFederal Communications Commissionflash memoryA type of EEPROM chip that can be reprogrammed from a utility on diskette while still installed in a computer; most EEPROM chips can only berewritten with special programming equipment.formatTo prepare a hard-disk drive or diskette for storing files.
