What system allows transferring messages from one computer to another?

The correct answer, E-mail: Electronic Mail, is a system specifically designed for sending and receiving messages between computers over the Internet. It allows users to compose messages, attach files, and send them to specific email addresses, all of which facilitates effective communication in a digital format. E-mail operates through a structured system of servers which manage the sending, receiving, and storing of messages, making it highly reliable for both personal and professional correspondence.

Other methods of communication, such as chat rooms and SMS messaging, serve different purposes. Chat rooms allow for real-time conversations among multiple users but are not primarily designed for message transfer between computers in a traditional sense. Telecommunication encompasses various forms of communication technologies including phone calls and data transmission but does not specifically refer to the structured messaging system that e-mail embodies.
