XIII Networking Challenges
As was pointed out before, 90% of
all network challenges are cable related. In a bus network, not terminating
the ends of the cable results in signal reflection or bounce, which
can be the cause of all sorts of havoc. If a terminator is defective,
which could happen easily if moisture got into the resistor, it could
look just like no termination.
 VOM Testing
If a network is not behaving test the cable and terminator with a VOM (Voltage Ohm Meter).

Somewhat more rare, but still quite
vexing is not all Ethernet networks are created equal. In fact there
are different types of Ethernet! This happened because Ethernet has
been around quite a while.
