A smart phone is a mobile phone that incorporates personal digital assistant (PDA) functionality. It allows users to make calls, send emails, access the internet, and edit office documents. Smart phones run operating systems like BlackBerry OS and have features such as touch screens, keyboards, web access, and messaging capabilities. While smart phones provide benefits like access to educational resources and the ability to work remotely, they can also distract students and enable cheating. The effects of smart phones on productivity, education, and social engagement depend on how each individual user chooses to utilize their device.
