Another advantage is the speed and reliability of computers. Their components are design to minimize the failure of the unit. The consistency of the computer allows the user to access and transmit information with a minimum amount of interference or delay. Unfortunately computers pose a several problems. A users privacy can be violated by hackers or criminals, who use the world wide web to access personal information. Identity theft has become a big concern for law enforcement and cyber detectives. Other disadvantages are health risk, labor issues, and environmental concerns.
