- Quick and real-time communication delivery

- Can simultaneously deliver messages to several recipients
- Accessible via the internet from any location
- Allows communications to be stored and documented.
History
Email (Electronic Mail) was first introduced in the early 1970s as a way to send messages between users on the same computer system. Ray Tomlinson is credited with sending the first networked email and introducing the “@” symbol to separate the user name and domain. Over time, email evolved with the growth of the internet and became a standard communication tool worldwide.
Working
Working of email involves a system of servers and communication protocols that handle sending and receiving messages. When a user sends an email, it is first delivered to a mail server, which then forwards it to the recipient’s mail server. The receiver can access the message using a mail client or a web-based service.
- Uses SMTP (Simple Mail Transfer Protocol) to send emails
- Uses POP3 or IMAP to receive emails
- Mail servers store and forward messages between users
Although email works efficiently through servers and protocols, its practical use also depends on its advantages and disadvantages.
