Longitudinal redundancy check
Okay kiddo, let's talk about something called Longitudinal Redundancy Check or LRC. Have you ever played with LEGO blocks and tried to build a tower that won't fall down? LRC is kind of like building a tower with LEGO blocks, but with computer data instead.
When we send data from one computer to another, we want to make sure that the data arrives safely and completely. LRC helps us do that by adding extra blocks of information to the data we send. These blocks are like LEGO blocks that help hold our data together and make sure it gets to its destination without falling apart.
Now, let's say we have a bunch of data we want to send, like a group of pictures or videos. We line up all the data in a row, like we're stacking LEGO blocks. Then we add a special LRC block at the end, which is like the top of our tower. This LRC block contains some additional information about the data we're sending.
Before we send this tower of data to another computer, we count all the blocks and make sure everything is correct. We also check the LRC block to make sure it matches the data we're sending. If everything checks out, we know that our tower of data is safe and sound and we can send it off to its destination.
But let's say something goes wrong and one of the blocks in our tower of data gets mixed up or lost on the way. When we check the LRC block, it won't match the data we're sending, and we'll know that something went wrong. We can then fix the problem and try sending the data again until everything matches up.
So you see, LRC is like building a tower with LEGO blocks to make sure our data arrives safely and completely. And just like with LEGO towers, if something goes wrong, we can fix it and try again.
