difference between 8bit and 16bit microcontroller

Dear all,
What is the difference bitween 8, 16 and 32 bit UC in point of view of Data processing, speed, code, performance.

I have gon thru lot of theory. but need actual practical experiences.

Thank you

Advantages: in a word, throughput. Disadvantages: More complications, board layout, more connections, greater cost, etc. Probably not a lot of difference in programming though. For general purpose use, eight bit is fine for most apps. Sixteen bit tends to be used in things like automotive real time ignition processing and other things at the same time. 32 bit, used for things like image processing etc. Check what you need, and read the specs. No point going overboard, you are generally just wasting power and money.
