ference.
RAM (J?cndom Access Memory):
within the computer circuitry itself.
RD (Receive Data):
between the computer and the printer.
RFI (Radio Frequency Interference):
ates radio frequency signals. The FCC regulates the amount of RFI a
computing device can 'leak' past its shielding. A Class A device is suf­
ficient for office use. Class B is a more stringent classification for
home equipment use. The TllOO complies with Class B computing
device regulations.
ROM (Read Only Memory):

RS232C:
ard that describes control, data and status signals for cable connectors
mating with computers, printers, communications and other periph­
eral devices.
RTS (Request to Send):
data between the computer and the printer.
s
SD (Send Data):
between the computer and the printer.
serial interface: An interface between systems or system components
in which information is transmitted sequentially , one unit at a time. In
computer systems with serial interface the transmission rate is one bit
at a time. Contrast: Parallel interface.
