When we upgrade our very outdated phones or laptops, sometimes, they cannot be upgraded directly to the latest version. First, We need to upgrade them to the one, in between the current one and the up-to-date one.
Could someone explain me in simple way? Thank you in advance.

instead of each update being a complete copy of a working system, which would let you install them regardless of the software already present, they only contain the bits that are different from the previous version. it reduces their size, but makes it a pain to update anything that hasn’t been online for a while. it’s usually not hard to help people who have skipped several updates by combining all the changed bits of those updates into 1 package, but there’s little incentive to do so
