Modem An artificial word concatenated from modulator and demodulator. A modem translates the
digital signals received from its local DTE to analog signals that are transmitted via a
telephone line. At the other end, the analog signals are demodulated and sent to the DTE as
digital signals again.
Modulation Translating digital states to analog waveforms.

Architecture Allows the system to be connected easily to devices and programs made by other
manufacturers. Open architectures use off-the-shelf components and conform to approved

answer mode.
Packed Data Data from which redundant information has been removed. Some file extensions denote
packed files. Standard extensions are .ZIP, .ARC, .LZH, .TAR, .ZOO and others. If you

transfer. Usual settings are even parity and odd parity. In a connection, the modems at both
ends must use the same parity settings.
