Computers have had a huge impact on the medical and military fields. In medicine, computers are used for cancer detection and running hospital functions. A new IBM computer called Watson can take a patient's history and create a personalized treatment plan, helping doctors with incorrect diagnoses. Watson gives doctors a new way to fight disease. The military also relies heavily on computers for intelligence gathering, data analysis, and weapon control like missiles and drones. A survey found that most people believe hospitals could not function without computers, while computers have most impacted the medical field. Computers will continue developing to assist in more ways.
