Imagine you have a really cool toy car that you want to make a copy of for your friend. You grab a blank piece of paper and a crayon, and start drawing the car onto the paper. The faster you move the crayon, the quicker you can finish drawing the car. This is kind of like CD and DVD writing speed.
When you write something onto a CD or DVD, you need to burn the information onto the disc. The faster the drive can burn the information, the quicker it can finish writing the whole CD or DVD. This is why CDs and DVDs have different writing speeds, so that you can choose how quickly you want to write the information onto them.
Just like how you need to move the crayon quickly to finish drawing the car faster, CD and DVD drives that have higher writing speeds can write information onto the disc more quickly. This means that you can create a copy of your favourite movie, for example, in a shorter amount of time with a faster writing speed.
However, it's important to note that not all CD and DVD drives can handle the same writing speeds. Just like how some people can run faster than others, some CD and DVD drives are better at writing at higher speeds than others. If you try to write something too quickly on a CD or DVD drive that can't handle the higher speed, it might not work properly or you might get errors. This is why it's important to make sure you use the correct writing speed for your CD or DVD drive, so that you get the best results.
