E-Mail
E-mail or electronic mail has been a part of the Internet's early uses by its developers since the 1960's. Timesharing computers across the early networks implemented a form of primitive email in which programs along the same system passed text only messages. Surprisingly, these programs also supported real-time messaging, something what we refer to today as instant messaging over the Internet.
SNDMSG & READMAIL:
Since the 1970’s, a team of programmers and developers under the guidance of Ray Tomlinson worked on a new operating system known as TENEX. The system supported a form of local email programs dubbed SNDMSG and READMAIL. A year later, Tomlinson developed ARPANET’s standard email application, which was based off the original SNDMSG. An additional feature known as CPYNET was added, allowing for the first time, files to be transferred over a network.
E-mail Addresses:
To further expand the range of e-mail addresses, he added the “@” symbol in combination with user and host names, establishing the standard of email addresses today “USER@HOST”.
Sendmail:
In the early 1980’s, Eric Allman developed the Sendmail program, which in essence paved together varying email transport services, creating a “switch” instead of an obsolete store-and-forward capability. Sendmail is still today, one of the most commonly used systems for delivering and controlling email to this day.
Conclusion:
E-mail has revolutionized communications on a global level. People can pass messages; transfer photos, and keep in touch with others around the world. Electronic mail is fast, convenient, cheep, and assessable to anyone with an Internet connection. Without a doubt, e-mail has played the crucial role for modernizing today’s means of communication and infrastructure.
