All are essential for connecting networks successfully
■ Media: This is the physical structure on which the signal will transmit (in wireless networks, this is
The open air). ■ Interface: This is the means by which the computer can access the media. ■ Signal: This is the means of transmission of information, such as electrical signals on copper wire. ■ Pattern: This is the established format for the signals to be interpreted by the computing device; a
Protocol is a more complex pattern that houses the individual bit patterns. ■ Timing: This is the established synchronization between the communicating devices so that each
Knows precisely when a pattern starts and ends.
