20 14 I want to take an examination of graduate students majoring in information security and countermeasures in the School of Information and Electronics of your university. I hope my brothers and sisters can give me some guidance. What does this major study? Employment prospect of communication and information system, signal and information processing. The development of information industry in the past two years has also met the needs of many people. Future research institutions and enterprises have two choices, each with its own long-term summary. With the high salaries of some foreign companies, it is relatively easy for some people in state-owned enterprises to study better in the future.
