Stock Roms/Custom ROMs
A Stock ROM is the version of the phone’s operating system that comes with your phone when you buy it.
A Custom ROM is a fully standalone version of the OS, including the kernel (which makes everything run), apps, services, etc – everything you need to operate the device, except it’s customized by someone in some way.
So what does the “customized” part mean? Since Android is open-source, developers are free to take stock ROMs, modify them, strip them of garbage, optimize them, add things, and pretty much do whatever their imagination and skills allow.
