ROM Read Only Memory devices. ROMs provide
nonvolatile memory, have a limited number of
write cycles, and include EPROMs,
EEPROMs, and flash memory.
ROM–DOS DOS operating system included in Micro PC
ROM.
Solid–State Disk A simulated disk using a high speed solid–
(SSD) state memory device, for example flash
memory, EEPROM, or static RAM.
Static RAM Static Random Access Memory device. Static
RAMs provide volatile memory with unlim-
ited read and write cycles. They may be used
with a battery back–up module.
TTL Compatible Transistor transistor logic compatible; 0–5V
logic levels.
Virtual Drive A disk created in DOS or extended memory
which emulates an actual disk. Provides
temporary storage for files. When power to
the computer is turned off the virtual drive
disappears.
XMODEM A communications protocol which allows
transfer of files between two computers.
XON/XOFF A communications protocol for asynchronous
connections. The receiver can pace the sender
by sending the XOFF and XON characters to
stop and continue the data flow.
H The suffix “H” denotes a hexadecimal num-
ber. A decimal number has no prefix or
suffix. For example, 1000H and 4096 are
equivalent.
