Modems are peripheral devices that enable PCs to communicate over long distances. ...
Data transmitted using modems is usually sent by asynchronous data transmission
using serial port connectors. ...
One of the key factors surrounding modems is how fast they are able to send signals.
The speed that modems transmit data is expressed in terms of the baud rate, which
represents the number of signal changes per second.
For very slow modems, the baud rate may equal the bits per second (bps) transmitted. ...
When youre comparing different modems, its more important to examine the bit rate
than the baud rate. ... 8 kbps modems. ...
Modems use data-compression methods to enable a greater number of bits to be transferred
at a given time.
As modems work in tandem with each other by modulating and demodulating signals,
having standards for data communication is essential. ...
Modems should be backward compatible. ... 90 bis, for 2x modems at 56 kbps, the V. ... 8 kbps modems. ...
Modems must also be able to provide error correction, and the V. ...
Modems can be external or internal to your PC.
External modems are standalone units that are powered separately.
Internal modems are installed as cards that are fitted into expansion slots, and
they are powered by the PC. ...
Then you take the phone cord and plug it into the modems TELCO jack, accessible
from the back of the PC. ...
You can change your modem settings by double-clicking the Modems icon in the Control
Panel.
