Paper documents are physical pieces of paper that contain written or printed information. They can include various types of content, such as letters, reports, contracts, and forms. These documents are often used for communication, record-keeping, and legal purposes. Despite the rise of digital technology, paper documents remain important in many settings, including businesses, schools, and government offices. They can be easily shared, signed, and stored, making them a reliable option for preserving information. However, they can also be susceptible to damage, loss, or deterioration over time.
