A fax machine is a physical device that sends and receives fax documents over a telephone line by scanning printed pages and converting them into electrical signals. These signals are transmitted to a receiving fax machine, which prints the document on paper.
While fax machines were once essential for business communications, they are increasingly being replaced by digital and online fax solutions. However, industries such as healthcare, legal, and government agencies still rely on fax machines due to regulatory requirements and security concerns.
