computer output microfilm (COM),
n a system that allows a computer user to produce microfilm copies of computer output. The COM unit operates independently of the CPU and is therefore called an
off-line device. Output from computer processing is recorded on generic media and later recorded on microfilm.
computer simulation,

Patient discussion about computer

Q. Where can i get the little computer for kids who have autism? I don't know what its called but its like a little computer or something that reads allowed what the person is writing.
