Telecom is a shorthand term for telecommunications, which refers to the transmission of information over distances through electronic means such as telephones, internet, radio, or television. In everyday language, 'a telecom' often refers to a telecommunications company—a business that provides communication services like phone, internet, or television to customers. Examples include AT&T, Verizon, Vodafone, and BT. Therefore, while 'telecom' itself is not a company, the term is commonly used to describe companies operating in the telecommunications industry.
