Transmission delay is when it takes time for information to travel from one place to another. Imagine you have a toy car that you want to send to your friend who lives far away. You have to place the car in a big box, write your friend’s address on the box, and send it through the post office. It will take a few days for the box to travel all the way to your friend’s house, and during that time, your friend won’t be able to play with the toy car.
Just like the toy car, data also needs to travel from one place to another, and it can take time for it to arrive. The speed at which data can travel depends on a lot of factors, like how far it needs to go, how much data there is, and how fast the internet connection is.
Sometimes, when you’re watching a video or playing an online game, you might notice that there’s a delay between when you push a button and when the action happens on your screen. That delay is caused by transmission delay – the data is taking some time to travel from your computer to the server where the game or video is hosted, and then back to your computer again.
Transmission delay is something that happens all the time when we use technology, and it’s just a part of how things work. But sometimes, we can try to make things faster by using faster internet connections or sending data in smaller pieces.
