A   computer USES the binary number system is counting way is determined by the logic devices used by the computer . This kind of logic devices is a  trigger circuit with two states  benefit is simple algorithms and implementation Convenient  system has the stability of the two states. The number in the computer can only be expressed in binary  hexadecimal Suitable for read-write convenience. 2. What is the development status of the MCU? And what are the application  try an example. A  microprocessors successfully developed in 1971. Fairchild  the United States in 1974 the company developed the worlds first single chip Microcomputer F8. This machine is composed of two integrated circuit chips  instruction systems with different  deep Welcome and attention in the field of civil electrical appliances and instruments. The beginning of a single chip microcomputer development  applications quickly Its expanding. Currently  microcontroller is developing in the direction o
