Computer literacy provides many benefits, but can also have costs if not used properly. There are three main costs discussed:
1. Social implications - overuse of social media and computers can negatively impact relationships as people spend less time with family and friends. It can also expose people to bad influences online from strangers.
2. Communication implications - common texting shorthand and online gaming language can negatively influence people's communication skills and perceptions from others. This may especially impact children.
3. Cyber crime - some with advanced computer skills may use them for illegal hacking, spreading viruses, or stealing sensitive information, which harms individuals, communities and national security. Proper precautions need to be taken to reduce such criminal behavior
