Internet Email

Electronic mail commonly known as email since 1993 A.D. Email is vital part of internet. Today email is popular than letter. Through email digital message can be exchange from one person to another person. Email is older than internet. Now days people sent their file and message through email. Letter take time to for delivery but email doesn't. Email is receive in minute or seconds. Internet email services reaches back to the early ARPANET. An email sent in the early 1970s looks quite similar to a basic text message sent on the Internet today. Email servers accept, forward, deliver, and store messages. Historically, the term electronic mail was used generically for any electronic document transmission. For example, several writers in the early 1970s used the term to describe fax document transmission. Originally a text-only (ASCII) communications medium, Internet email was extended to carry, e.g., text in other character sets, multimedia content attachments, a process standardized in RFC 2045 through 2049. Collectively, these RFCs have come to be called Multipurpose Internet Mail Extensions (MIME).

World Wide Web (WWW)

The World Wide Web commonly known as WWW or understand as web. WWW is a system of interlinked hypertext documents accessed via the Internet. WWW can be access through a program called browser. With a web browser, one can view web pages that may contain text, images, videos, and other multimedia, and navigate between them via hyperlinks. The web was developed between March 1989 and December 1990. The 1989 proposal was meant for a more effective CERN communication system but Berners-Lee eventually realised the concept could be implemented throughout the world. Using concepts from his earlier hypertext systems like ENQUIRE, British engineer, computer scientist and at that time employee of the CERN, Tim Berners-Lee, now Director of the World Wide Web Consortium (W3C), wrote a proposal in March 1989 for what would eventually become the World Wide Web. At CERN, a European research organisation near Geneva straddling the border between France and Switzerland, Berners-Lee and Belgian computer scientist Robert Cailliau proposed in 1990 to use hypertext "to link and access information of various kinds as a web of nodes in which the user can browse at will and Berners-Lee finished the first website in December that year. Berners-Lee posted the project on the alt.hypertext newsgroup on 7 August 1991.
