what i sthe difference between mmos and pmos transistors?

Answer 1

I think you mean NMOS and PMOS and they stand for 'N-channel metal oxide semiconductor' and P-channel metal oxide semiconductor'. The difference between them is that the conduction channel is either N-type silicon or P-type silicon.

Answer 2

Do you mean psychologist and psychiatrist? If so, A psychologist is a scientist and/or clinician who studies psychology, the systematic investigation of the human mind, including behavior and cognition. Psychologists are usually categorized under a number of different fields, the most well-recognized being clinical psychologists, who provide mental health care, and research psychologists, who collect, investigate and analyze aspects of human behavior. A psychiatrist is a medical doctor: Psychiatry is a medical specialty dealing with the prevention, assessment, diagnosis, treatment, and rehabilitation of mental illness – both in itself and in bodily illness ('psychiatry in medicine') – such as clinical depression, bipolar disorder, schizophrenia and anxiety disorders. Its primary goal is the relief of mental suffering and improvement of mental well-being. This is sometimes done by first doing a thorough diagnostic assessment of the person from a biological, psychological, and social/cultural perspective. An illness or problem can then be managed by medication or various forms of psychotherapy. The word 'psychiatry' derives from the Greek for "healer of the spirit".
