Digital literacy refers to the ability to read, write, and understand information in a digital environment. It involves the skills needed to operate in a technology-driven world, including reading online content, communicating digitally, and using computers for tasks like exams. While computers can enhance digital literacy, they also enable issues like plagiarism, as some students inappropriately copy others' work online. Teachers must educate students on these issues and discourage cheating to help students develop their skills and knowledge through ethical means.
