Email, a widely used communication medium, has been a crucial part of daily life since its inception in 1975. It is a system that operates across computer^[1] networks and the internet^[2], allowing messages to be sent and received globally. The term ‘email’ is preferred in style guides, but variations like ‘E-mail’ are sometimes used, particularly in American and British English writing. This system’s operation involves a sender formatting a message using a Mail User Agent (MUA), which is then forwarded to the recipient’s mail exchange server. The recipient’s MUA retrieves the message. With the help of the Multipurpose Internet Mail Extension (MIME), emails can now carry multimedia content. For security^[3], email systems use a store-and-forward model, where email servers accept, forward, deliver, and store messages. This allows users to exchange emails without the need for simultaneous online presence.

Terms definitions

1. ↑ computer. A computer is a sophisticated device that manipulates data or information according to a set of instructions, known as programs. By design, computers can perform a wide range of tasks, from simple arithmetic calculations to complex data processing and analysis. They have evolved over the years, starting from primitive counting tools like abacus to modern digital machines. The heart of a computer is its central processing unit (CPU), which includes an arithmetic logic unit (ALU) for performing mathematical operations and registers for storing data. Computers also have memory units, like ROM and RAM, for storing information. Other components include input/output (I/O) devices that allow interaction with the machine and integrated circuits that enhance the computer's functionality. Key historical innovations, like the invention of the first programmable computer by Charles Babbage and the development of the first automatic electronic digital computer, the Atanasoff-Berry Computer (ABC), have greatly contributed to their evolution. Today, computers power the Internet, linking billions of users worldwide and have become an essential tool in almost every industry.

2. ↑ internet. The Internet is a global system of interconnected computer networks that use standardized communication protocols, primarily the TCP/IP, to link devices worldwide. Originating from the term 'internetted' used in 1849, the term 'Internet' was later used by the US War Department in 1945. Its development began with computer scientists creating time-sharing systems in the 1960s and further progressed with the establishment of ARPANET in 1969. The Internet is self-governed, without a central authority, and its principal name spaces are administered by the Internet Corporation for Assigned Names and Numbers (ICANN). It has significantly transformed traditional communication media and has grown exponentially over the years, with internet users increasing 20% to 50% annually. In 2019, over half of the world population used the Internet. The Internet protocol suite, which includes TCP/IP and four conceptual layers, guides internet packets to their destinations. Essential services like email and Internet telephony operate on the Internet. The World Wide Web, a global collection of interconnected documents, is a key component of the Internet.

Email (Wikipedia)

Electronic mail (email or e-mail) is a method of transmitting and receiving messages using electronic devices. It was conceived in the late–20th century as the digital version of, or counterpart to, mail (hence e- + mail). Email is a ubiquitous and very widely used communication medium; in current use, an email address is often treated as a basic and necessary part of many processes in business, commerce, government, education, entertainment, and other spheres of daily life in most countries.

Email operates across computer networks, primarily the Internet, and also local area networks. Today's email systems are based on a store-and-forward model. Email servers accept, forward, deliver, and store messages. Neither the users nor their computers are required to be online simultaneously; they need to connect, typically to a mail server or a webmail interface to send or receive messages or download it.

Originally an ASCII text-only communications medium, Internet email was extended by Multipurpose Internet Mail Extensions (MIME) to carry text in other character sets and multimedia content attachments. International email, with internationalized email addresses using UTF-8, is standardized but not widely adopted.
