192-bit
The older version of IP has a ________ header of control information.
spikes
The primary source of error in data communications is:
which application layer process the packet is from.
The source port identifier of the received TCP segment tells the destination station _____________.
digital and analog
Two fundamentally different types of data are:
echo
When a signal is reflected back to the transmitting equipment, it is called a(n) _________.
