Wht is the 16bit compiler?

what does the term 16 bit stand for in a c compiler???

Wht is the 16bit compiler?
Intel CPUs were originally 16 bit machines. When 32-bit CPUs were released they ran in a new 32-bit mode, but were still able to switch to the original 16-bit mode so that they could still run all existing software. Programs that are written for 16-bit mode will run on machines with both 16-bit CPUs (i.e. the 80286 and earlier) and 32-bit CPUs. Applications compiled for 32-bit mode will only run on 32-bit architecture. 16-bit is now obsolete, so you should always compile for 32-bit; it's both faster and gives you access to a far greater memory address space.
