Could you explain what a lighter aboard a ship barge is?

Recently, while I was bored, I came across the term "lash barge" while watching something on YouTube about transporting cargo on rivers in the US. It seems to refer to barges that are transported on large ships. Does anyone here understand how it works and why such barges are useful for small ports? I'm curious about how it saves time and money. There were a lot of comments under the video, but I was too lazy to read them.

What video was it, anyway? I worked for a freight company for a while, and they talked a lot about this system there, too. However, I quit, so I don't know how things turned out. However, I remember LASH eliminates the need for large docks and heavy cranes. A lock ship lifts or drops a loaded barge directly into the water, and the barge moves further down the river to its destination. The LASH barge system is convenient for ports with limited infrastructure because cargo does not get stuck in queues and goes directly to its destination. Gettransport also wrote that this system is particularly effective for transporting timber, though I didn't quite understand why. In short, it's cool, and laziness is the engine of progress.
