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 causes packet delay?
Packet delay is caused by several factors, including propagation delay, transmission delay, queuing delay, and processing delay. Propagation delay occurs as packets travel through the medium, while transmission delay is the time taken to push all packet bits onto the network. Queuing delay happens when packets wait in line at routers or switches due to network congestion, and processing delay is the time taken by devices to process the packet headers and make forwarding decisions. Each of these factors can contribute to the overall delay experienced in data transmission.
What are the 4 main types of delays occured in packet switching?
Processing delay Queuing delay Transmission delay Propagation delay
How resistance and propagation delay related each other in TTL logic family?
In TTL (Transistor-Transistor Logic) circuits, resistance and propagation delay are inversely related. Higher resistance in the circuit can lead to increased propagation delay, as it affects the charging and discharging times of capacitive loads. This delay is primarily due to the time it takes for the output to transition from one state to another, which is influenced by the RC time constant (where R is resistance and C is capacitance). Thus, optimizing resistance is crucial for improving speed in TTL logic applications.
Which has a shorter propagation delay TTL or CMOS?
TTL
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 is the condition for minimum size of the token ring?
propagation delay in the ring/transmission delay of the packet<1
What is value of propagation delay of TTL logic?
it is in micro seconds
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 is the Formula to calculate time delay?
The formula to calculate time delay is typically expressed as ( \text{Time Delay} = \frac{\text{Distance}}{\text{Speed}} ). This formula determines how long it takes for a signal or wave to travel a certain distance at a given speed. In various contexts, such as telecommunications or physics, time delay can also be influenced by factors like processing time or propagation delays.
What are two types of fixed network delays?
Two types of fixed network delays are transmission delay and propagation delay. Transmission delay is the time it takes to push all the packet's bits into the wire, determined by the packet's size and the bandwidth of the link. Propagation delay, on the other hand, is the time it takes for a signal to travel from the sender to the receiver, which depends on the distance between them and the speed of the signal in the medium. Both delays are constant for a given network configuration.
