Technology has had a major impact on education by allowing access to vast amounts of shared information and enabling distance learning. It also supports roles in universities, schools, and other education systems through tools like projectors and whiteboards. However, social media in particular has both positive and negative effects by helping people connect but also enabling inappropriate behavior and negative situations. New communication technologies beyond phones now allow video chatting on computers and laptops. Healthcare has benefited from new information available online but must be carefully researched, as some seek to take advantage of those without knowledge. Relationships are also impacted as online dating sites help people meet but also enable deception.
