What is beeper communication?

Beeper communication refers to the use of a beeper or pager, a small electronic device that receives and displays messages, often in the form of numeric codes or short text. Historically popular in the 1980s and 1990s, beepers allowed users to receive alerts about calls or messages when they were away from a landline phone. While largely replaced by mobile phones, beepers are still used in certain professional settings, such as healthcare, for their reliability and simplicity in emergency communication.
