It's the time it takes a radio signal to travel from one place to another, the time it
takes a light beam to travel from one end of the fiberoptic cable to the other end,
the time it takes an electrical signal to travel from one side of a circuit board to the
other side, etc., things like that.
If you're listening to the Baseball game on the radio, it doesn't much matter how
long it took the signal to reach you from the transmitting tower. But if the radio
signal is being used to control a high-speed passenger train, or a drone aircraft
on a counter-insurgency mission, or a robotic rover digging in the dirt on Mars,
then the time it takes the radio signal to get there does make a difference.

What best defines propagation delay?
Propagation delay is the time it takes for electronic devices to switch from one logic state to another.
What is another name for propagation delay?
Another name for propagation delay is latency.
What are the 4 main types of delays occured in packet switching?
Processing delay Queuing delay Transmission delay Propagation delay
Which has a shorter propagation delay TTL or CMOS?
TTL
What is value of propagation delay of TTL logic?
it is in micro seconds
What is the condition for minimum size of the token ring?
propagation delay in the ring/transmission delay of the packet<1
What is propogation delay in satellite?
A propagation delay is the amount of time it takes radio waves to travel from the surface of the Earth to the satellite and then back down to the Earth. The calculation of the delay is based upon the altitude and position of the satellite systems.
What types of delay are significant in assessing the performance of a packet-switching network?
Propagation delay: The time it takes a signal to propagate from one node to the next. Transmission Time: The time it takes for a transmitter to send out a block of data. Node Delay: The time it takes for a node to perform the necessary processing as it switches the data.
What are the characteristics of Diode transistor logic?
relatively large propagation delay.
What is propagation delay in flip flops?
Propagation Delay In digital logic, every gate has got some finite amount of delay because of which the change in the output is not instantaneous to the change in the input. In simple terms, the times it takes for an input to appear at the output is called the propagation delay. In Figure 6, tPHL, describes the time it takes for an input to cause the output to change from logic-level-high to logic-level-low. Similarly, tPLH, refers to the delay associated when an input change causes the output to change from logic-level-low to logic-level-high. The overall delay is average of these two delays.
How can Propagation delay be avoided in a parallel adder?
The parallel adder which we use in the digital circuits ,the carry output of each full adder stage is connected to the carry input of the next higher order stage.therefore,the sum and carry outputs of any stage cannot be produced until the input carry occurs; This leads to a time delay in the addition process.This delay is known as carry propagation delay. to the second question the propagation delay can be avoided in the binary parallel adder with the help of look ahead carry generator .............................................................................................................................
Explain how propagation delay affects the speed of modern PCs?
A: I wouldn't call propagation delay that applies to other media. for a PC delay are parasitic in nature mostly layout. But the real and actual delay is inherited from the I/O which is the soul of PC speed. No matter how fast a PC is internally it must service those interrupts and that is really the delay actually
