Can you explain the functionality of icon maps (or charts)?

As I was exploring the source code of various websites, I noticed a common pattern - all the icons were stored in one image map. Upon further investigation, I discovered that each icon is referenced individually when needed. I came across a helpful article about image mapping on W3Schools which provided me with the basic concept, but I'm still curious about how it actually works. Can anyone point me towards more resources or articles to dig deeper into this topic? Thanks in advance!
