It means: cannot be changed or altered (by some internal variable setting or
function or new algorithm).
A software programme can be loaded into a RAM or onto a disk. In the RAM, or
disk, you can change it with patches or other means. You can also load it on to
a CD oder DVD or into a ROM/PROM. These all are read-only devices, although
some of them can be one-time written. The programme on these devices is
hard-wired, its functions are interconnected with a kind of hardware or real
wires as if you had an experimentation board in which you insert (instead of
software function blocks) ICs, transistors, resistors, capacitors and
"programme" them by soldering wires to the components to make the board
(programme) work as something, as some electric or electronic circuit. When you
load the software into a CPU's RAM you can re-wire the function blocks any
time, because their interconnects are not that "hard".
